2021-09-15Redirect fma calls to __fma in libmJoseph Myers
include/math.h has a mechanism to redirect internal calls to various libm functions, that can often be inlined by the compiler, to call non-exported __* names for those functions in the case when the calls aren't inlined, with the redirection being disabled when NO_MATH_REDIRECT. Add fma to the functions to which this mechanism is applied. At present, libm-internal fma calls (generally to __builtin_fma* functions) are only done when it's known the call will be inlined, with alternative code not relying on an fma operation being used in the caller otherwise. This patch is in preparation for adding the TS 18661 / C2X narrowing fma functions to glibc; it will be natural for the narrowing function implementations to call the underlying fma functions unconditionally, with this either being inlined or resulting in an __fma* call. (Using two levels of round-to-odd computation like that, in the case where there isn't an fma hardware instruction, isn't optimal but is certainly a lot simpler for the initial implementation than writing different narrowing fma implementations for all the various pairs of formats.) Tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by the patch (using <https://sourceware.org/pipermail/libc-alpha/2021-September/130991.html> to fix installed library stripping in build-many-glibcs.py). Also tested for x86_64.

2020-02-28ldbl-128ibm-compat: Redirect long double functions to f128/ieee128 functionsTulio Magno Quites Machado Filho
Modify the headers to redirect long double functions to global __*f128 symbols or to __*ieee128 otherwise. Most of the functions in math.h benefit from the infrastructure already available for __LDBL_COMPAT. The only exceptions are nexttowardf and nexttoward that need especial treatment. Both math/bits/mathcalls-helper-functions.h and math/bits/mathcalls.h were modified in order to provide alternative redirection destinations that are essential to support functions that should not be redirected to the same name pattern of the rest of the functions, i.e.: __fpclassify, __signbit, __iseqsig, __issignaling, isinf, finite and isnan, which will be redirected to __*f128 instead of __*ieee128 used for the rest.

Continuing the move to use, within libm, public names for libm functions that can be inlined as built-in functions on many architectures, this patch moves calls to __copysign functions to call the corresponding copysign names instead, with asm redirection to __copysign when the calls are not inlined (all cases are inlined except for IBM long double for powerpc soft-float / e500v1).

2018-09-27Use round functions not __round functions in glibc libm.Joseph Myers
Continuing the move to use, within libm, public names for libm functions that can be inlined as built-in functions on many architectures, this patch moves calls to __round functions to call the corresponding round names instead, with asm redirection to __round when the calls are not inlined. An additional complication arises in sysdeps/ieee754/ldbl-128ibm/e_expl.c, where a call to roundl, with the result converted to int, gets converted by the compiler to call lroundl in the case of 32-bit long, so resulting in localplt test failures. It's logically correct to let the compiler make such an optimization; an appropriate asm redirection of lroundl to __lroundl is thus added to that file (it's not needed anywhere else).

2018-09-14Use floor functions not __floor functions in glibc libm.Joseph Myers
Similar to the changes that were made to call sqrt functions directly in glibc, instead of __ieee754_sqrt variants, so that the compiler could inline them automatically without needing special inline definitions in lots of math_private.h headers, this patch makes libm code call floor functions directly instead of __floor variants, removing the inlines / macros for x86_64 (SSE4.1) and powerpc (POWER5). The redirection used to ensure that __ieee754_sqrt does still get called when the compiler doesn't inline a built-in function expansion is refactored so it can be applied to other functions; the refactoring is arranged so it's not limited to unary functions either (it would be reasonable to use this mechanism for copysign - removing the inline in math_private_calls.h but also eliminating unnecessary local PLT entry use in the cases (powerpc soft-float and e500v1, for IBM long double) where copysign calls don't get inlined). The point of this change is that more architectures can get floor calls inlined where they weren't previously (AArch64, for example), without needing special inline definitions in their math_private.h, and existing such definitions in math_private.h headers can be removed. Note that it's possible that in some cases an inline may be used where an IFUNC call was previously used - this is the case on x86_64, for example. I think the direct calls to floor are still appropriate; if there's any significant performance cost from inline SSE2 floor instead of an IFUNC call ending up with SSE4.1 floor, that indicates that either the function should be doing something else that's faster than using floor at all, or it should itself have IFUNC variants, or that the compiler choice of inlining for generic tuning should change to allow for the possibility that, by not inlining, an SSE4.1 IFUNC might be called at runtime - but not that glibc should avoid calling floor internally. (After all, all the same considerations would apply to any user program calling floor, where it might either be inlined or left as an out-of-line call allowing for a possible IFUNC.)

2018-09-05Move float128 inlines from sysdeps/generic/math_private.h to include/math.h.Joseph Myers
Continuing the cleanup of math_private.h, with a view to it becoming the header for the APIs defined therein and not also a header with inline variants of math.h APIs, this patch moves inline definitions of __isinff128 and fabsf128 to include/math.h, so that any users of math.h in glibc automatically get the optimized functions rather than quietly missing them if they do not also include math_private.h. Tested for x86_64 and x86, and with build-many-glibcs.py with GCC 6. There are changes to installed stripped libc.so on configurations with distinct _Float128, because of __printf_fp_l code that now gets the __isinff128 inline where previously it called the out-of-line function because of the lack of a math_private.h call. It seems appropriate that this code does get the inline (as it would automatically with GCC 7 and later when the built-in function is used) rather than being the only place in glibc that does not. * sysdeps/generic/math_private.h [__HAVE_DISTINCT_FLOAT128 && !__GNUC_PREREQ (7, 0)] (__isinff128): Move this inline function .... [__HAVE_DISTINCT_FLOAT128] (fabsf128): And this one .... * include/math.h [!_ISOMAC]: To here....
2018-03-15Add support for sqrt asm redirectsWilco Dijkstra
This patch series cleans up the many uses of __ieee754_sqrt(f/l) in GLIBC. The goal is to enable GCC to do the inlining, and if this fails call the __ieee754_sqrt function. This is done by internally declaring sqrt with asm redirects. The compat symbols and sqrt wrappers need to disable the redirect. The redirect is also disabled if there are already redirects defined when using -ffinite-math-only. All math functions (but not math tests, non-library code and libnldbl) are built with -fno-math-errno which means GCC will typically inline sqrt as a single instruction. This means targets are no longer forced to add a special inline for sqrt. * include/math.h (sqrt): Declare with asm redirect. (sqrtf): Likewise. (sqrtl): Likewise. (sqrtf128): Likewise. * Makeconfig: Add -fno-math-errno for libc/libm, but build testsuite, nonlib and libnldbl with -fmath-errno. * math/w_sqrt_compat.c: Define NO_MATH_REDIRECT. * math/w_sqrt_template.c: Likewise. * math/w_sqrtf_compat.c: Likewise. * math/w_sqrtl_compat.c: Likewise. * sysdeps/i386/fpu/w_sqrt.c: Likewise. * sysdeps/i386/fpu/w_sqrt_compat.c: Likewise. * sysdeps/generic/math-type-macros-float128.h: Remove math.h and complex.h.
2017-10-30Remove _Mlong_double_ etc. macros.Joseph Myers
math.h has a macro _Mlong_double_ for the type to use when declaring long double functions, and similar macros for other types. math/Makefile uses -D_Mlong_double_=double in the case of long double having the same ABI as double. This originates with: Mon Jul 8 13:37:40 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu> * math/math.h (_Mfloat_, _Mlong_double_): New macros, defined iff not already defined to float, long double. Use those macros for _Mdouble_ defns when including mathcalls.h. * math/Makefile [$(long-double-fcts) != yes] (CPPFLAGS): Append -D_Mlong_double_=double. However, math.h stopped declaring long double functions in the case of long double having the same ABI as double (and thus probably stopped actually needing the Makefile definition of _Mlong_double_) with: 1998-11-05 Ulrich Drepper <drepper@cygnus.com> * math/math.h: Unconditionally include bits/mathdef.h. Declare long double functions only if __NO_LONG_DOUBLE_MATH is not defined. * sysdeps/generic/bits/mathdef.h: Define only if __USE_ISOC9X. Define __NO_LONG_DOUBLE_MATH. * sysdeps/m68k/fpu/bits/mathdef.h: Define only if __USE_ISOC9X. * sysdeps/i386/fpu/bits/mathdef.h: Likewise. The declarations were since restored for compiling user code, but remain absent when _LIBC is defined, which is sufficient to avoid problems declaring function aliases of incompatible types. Thus the indirection through the _Mlong_double_ macro is not needed (probably since that 1998 patch), and this patch removes _Mlong_double_ and associated macros for other types, leaving only the macro _Mdouble_ which is actually used as the type for which a given inclusion of <bits/mathcalls.h> should declared functions. Tested for x86_64, and tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by this patch. * math/math.h [!_Mfloat_] (_Mfloat_): Do not define.

2017-09-14Make more libm functions into weak aliases.Joseph Myers
Many libm functions define the function as __<func> and then define <func> as a weak alias. This is not at all limited to cases where there is an internal call that has namespace reasons to need to call __<func> instead of <func>. The common macros for creating libm function aliases work on the basis of public function names all being aliases; that is, they define aliases for functions using the above pattern. Thus, where a function just defines the public name <func> directly, changing that to be a weak alias enables a subsequent conversion to the common macros to retain the exact existing symbols (and so be testable by comparison of stripped binaries). This patch converts many existing functions to use the weak alias pattern, as preparation for subsequent conversions to common macros. I do expect that _FloatN/_FloatNx function aliases will end up needing new variants of the common macros that do *not* create the original float / double / long double name of a function - for cases where that name is created specially to give it a particular symbol version, for example - but for functions that can use the most common macros to create all the public names as aliases, it makes sense for them to do so. Regarding the Bessel function wrappers in this patch: only float and double wrappers are changed because the long double wrappers already used the weak alias pattern.

2017-08-21Obsolete matherr, _LIB_VERSION, libieee.a.Joseph Myers
This patch obsoletes support for SVID libm error handling (the system where a user-defined function matherr is called on a libm function error; only enabled if you also set _LIB_VERSION = _SVID_ or _LIB_VERSION = _XOPEN_) and the use of the _LIB_VERSION global variable to control libm error handling. matherr and _LIB_VERSION are made into compat symbols, not supported for new ports or for static linking. The libieee.a object file (which sets _LIB_VERSION = _IEEE_, so disabling errno setting for some functions) is also removed, and all the related definitions are removed from math.h. The manual already recommends against using matherr, and it's already not supported for _Float128 functions (those use new wrappers that don't support matherr, only errno) - this patch means that it becomes possible to e.g. add sinf32 as an alias to sinf without that resulting in undesired matherr support in sinf32 for existing glibc ports. matherr support is not part of any standard supported by glibc (it was removed in XPG4). Because matherr is a function to be defined by the user, of course user programs defining such a function will still continue to link; it just quietly won't be used. If they try to write to the library's copy of _LIB_VERSION to enable SVID error handling, however, they will get a link error (but if they define their own _LIB_VERSION variable, they won't). I expect the most likely case of build failures from this patch to be programs with unconditional cargo-culted uses of -lieee (based on a notion of "I want IEEE floating point", not any actual requirement for that library). Ideally, the new-port-or-static-linking case would use the new wrappers used for _Float128. This is not implemented in this patch, because of the complication of architecture-specific (powerpc32 and sparc) sqrt wrappers that use _LIB_VERSION and __kernel_standard directly. Thus, the old wrappers and __kernel_standard are still built unconditionally, and _LIB_VERSION still exists in static libm. But when the old wrappers and __kernel_standard are built in the non-compat case, _LIB_VERSION and matherr are defined as macros so code to support those features isn't actually built into static libm or new ports' shared libm after this patch. I intend to move to the new wrappers for static libm and new ports in followup patches. I believe the sqrt wrappers for powerpc32 and sparc can reasonably be removed. GCC already optimizes the normal case of sqrt by generating code that uses a hardware instruction and only calls the sqrt function if the argument was negative (if -fno-math-errno, of course, it just uses the hardware instruction without any check for negative argument being needed). Thus those wrappers will only actually get called in the case of negative arguments, which is not a case it makes sense to optimize for. But even without removing the powerpc32 and sparc wrappers it should still be possible to move to the new wrappers for static libm and new ports, just without having those dubious architecture-specific optimizations in static libm. Everything said about matherr equally applies to matherrf and matherrl (IA64-specific, undocumented), except that the structure of IA64 libm means it won't be converted to using the new wrappers (it doesn't use the old ones either, but its own error-handling code instead). As with other tests of compat symbols, I expect test-matherr and test-matherr-2 to need to become appropriately conditional once we have a system for disabling such tests for ports too new to have the relevant symbols.

2017-06-30float128: Add signbit alternative for old compilersGabriel F. T. Gomes
In math/math.h, __MATH_TG will expand signbit to __builtin_signbit*, e.g.: __builtin_signbitf128, before GCC 6. However, there has never been a __builtin_signbitf128 in GCC and the type-generic builtin is only available since GCC 6. For older GCC, this patch defines __builtin_signbitf128 to __signbitf128, so that the internal function is used instead of the non-existent builtin. This patch also changes the implementation of __signbitf128, because it was reusing the implementation of __signbitl from ldbl-128, which calls __builtin_signbitl. Using the long double version of the builtin is not correct on machines where _Float128 is ABI-distinct from long double (i.e.: ia64, powerpc64le, x86, x86_84). The new implementation does not rely on builtins when being built with GCC versions older than 6.0. The new code does not currently affect powerpc64le builds, because only GCC 6.2 fulfills the requirements from configure. It might affect powerpc64le builds if those requirements are backported to older versions of the compiler. The new code affects x86_64 builds, since glibc is supposed to build correctly with older versions of GCC. Tested for powerpc64le and x86_64. * include/math.h (__signbitf128): Define as hidden. * sysdeps/ieee754/float128/s_signbitf128.c (__signbitf128): Reimplement without builtins. * sysdeps/ia64/bits/floatn.h [!__GNUC_PREREQ (6, 0)] (__builtin_signbitf128): Define to __signbitf128. * sysdeps/powerpc/bits/floatn.h: Likewise. * sysdeps/x86/bits/floatn.h: Likewise.

2017-05-11Suppress internal declarations for most of the testsuite.Zack Weinberg
This patch adds a new build module called 'testsuite'. IS_IN (testsuite) implies _ISOMAC, as do IS_IN_build and __cplusplus (which means several ad-hoc tests for __cplusplus can go away). libc-symbols.h now suppresses almost all of *itself* when _ISOMAC is defined; in particular, _ISOMAC mode does not get config.h automatically anymore. There are still quite a few tests that need to see internal gunk of one variety or another. For them, we now have 'tests-internal' and 'test-internal-extras'; files in this category will still be compiled with MODULE_NAME=nonlib, and everything proceeds as it always has. The bulk of this patch is moving tests from 'tests' to 'tests-internal'. There is also 'tests-static-internal', which has the same effect on files in 'tests-static', and 'modules-names-tests', which has the *inverse* effect on files in 'modules-names' (it's inverted because most of the things in modules-names are *not* tests). For both of these, the file must appear in *both* the new variable and the old one. There is also now a special case for when libc-symbols.h is included without MODULE_NAME being defined at all. (This happens during the creation of libc-modules.h, and also when preprocessing Versions files.) When this happens, IS_IN is set to be always false and _ISOMAC is *not* defined, which was the status quo, but now it's explicit. The remaining changes to C source files in this patch seemed likely to cause problems in the absence of the main change. They should be relatively self-explanatory. In a few cases I duplicated a definition from an internal header rather than move the test to tests-internal; this was a judgement call each time and I'm happy to change those however reviewers feel is more appropriate. * Makerules: New subdir configuration variables 'tests-internal' and 'test-internal-extras'. Test files in these categories will still be compiled with MODULE_NAME=nonlib. Test files in the existing categories (tests, xtests, test-srcs, test-extras) are now compiled with MODULE_NAME=testsuite. New subdir configuration variable 'modules-names-tests'. Files which are in both 'modules-names' and 'modules-names-tests' will be compiled with MODULE_NAME=testsuite instead of MODULE_NAME=extramodules. (gen-as-const-headers): Move to tests-internal. (do-tests-clean, common-mostlyclean): Support tests-internal. * Makeconfig (built-modules): Add testsuite. * Makefile: Change libof-check-installed-headers-c and libof-check-installed-headers-cxx to 'testsuite'. * Rules: Likewise. Support tests-internal. * benchtests/strcoll-inputs/filelist#en_US.UTF-8: Remove extra-modules.mk. * config.h.in: Don't check for __OPTIMIZE__ or __FAST_MATH__ here. * include/libc-symbols.h: Move definitions of _GNU_SOURCE, PASTE_NAME, PASTE_NAME1, IN_MODULE, IS_IN, and IS_IN_LIB to the very top of the file and rationalize their order. If MODULE_NAME is not defined at all, define IS_IN to always be false, and don't define _ISOMAC. If any of IS_IN (testsuite), IS_IN_build, or __cplusplus are true, define _ISOMAC and suppress everything else in this file, starting with the inclusion of config.h. Do check for inappropriate definitions of __OPTIMIZE__ and __FAST_MATH__ here, but only if _ISOMAC is not defined. Correct some out-of-date commentary. * include/math.h: If _ISOMAC is defined, undefine NO_LONG_DOUBLE and _Mlong_double_ before including math.h. * include/string.h: If _ISOMAC is defined, don't expose _STRING_ARCH_unaligned.

2016-12-21Add roundeven, roundevenf, roundevenl.Joseph Myers
TS 18661-1 defines roundeven functions that round a floating-point number to the nearest integer, in that floating-point type, with ties rounding to even (whereas the round functions round ties away from zero). As with other such functions, they raise no exceptions apart from "invalid" for signaling NaNs. There was a previous user request for this functionality in glibc in <https://sourceware.org/ml/libc-help/2015-02/msg00005.html>. This patch implements these functions for glibc. The implementations use integer bit-manipulation (or roundeven on the high and low parts, in the IBM long double case). It's possible that there may be faster approaches on some architectures (in particular, on AArch64 the frintn instruction should do exactly what's required); I'll leave it to architecture maintainers or others interested to implement such architecture-specific versions if desired. (Where architectures have instructions to round to nearest integer in the current rounding mode, implementations saving and restoring the rounding mode - and dealing with exceptions if those instructions generate "inexact" - are also possible, though their performance depends on the cost of manipulating exceptions / rounding mode state.)

2015-11-20Fix lgamma setting signgam for ISO C (bug 15421).Joseph Myers
The lgamma (and likewise lgammaf, lgammal) function wrongly sets the signgam variable even when building for strict ISO C conformance (-std=c99 / -std=c11), although the user may define such a variable and it's only in the implementation namespace for POSIX with XSI extensions enabled. Following discussions starting at <https://sourceware.org/ml/libc-alpha/2013-04/msg00767.html> and <https://sourceware.org/ml/libc-alpha/2015-10/msg00844.html>, it seems that the safest approach for fixing this particular issue is for signgam to become a weak alias for a newly exported symbol __signgam, with the library functions only setting __signgam, at which point static linker magic will preserve the alias for newly linked binaries that refer to the library's signgam rather than defining their own, while breaking the alias for programs that define their own signgam, with new symbol versions for lgamma functions and with compat symbols for existing binaries that set both signgam and __signgam. This patch implements that approach for the fix. signgam is made into a weak alias. The four symbols __signgam, lgamma, lgammaf, lgammal get new symbol versions at version GLIBC_2.23, with the existing versions of lgamma, lgammaf and lgammal becoming compat symbols. When the compat versions are built, gamma, gammaf and gammal are aliases for the compat versions (i.e. always set signgam); this is OK as they are not ISO C functions, and avoids adding new symbol versions for them unnecessarily. When the compat versions are not built (i.e. for static linking and for future glibc ports), gamma, gammaf and gammal are aliases for the new versions that set __signgam. The ldbl-opt versions are updated accordingly. The lgamma wrappers are adjusted so that the same source files, included from different files with different definitions of USE_AS_COMPAT, can build either the new versions or the compat versions. Similar changes are made to the ia64 versions (untested). Tests are added that the lgamma functions do not interfere with a user variable called signgam for ISO C, with various choices for the size of that variable, whether it is initialized, and for static and dynamic linking. The conformtest whitelist entry is removed as well. Tested for x86_64, x86, mips64 and powerpc, including looking at objdump --dynamic-syms output to make sure the expected sets of symbols were aliases. Also spot-tested that a binary built with old glibc works properly (i.e. gets signgam set) when run with new glibc.
