2020-05-06semaphore: consolidate arch headers into a generic oneVineet Gupta
This consolidates the copy-pasted arch specific semaphore header into single version (based on s390) which suffices 32-bit and and 64-bit arch/ABI based on the canonical WORDSIZE. For now I've left out arches which use alternate defines to choose for 32 vs 64-bit builds (aarch64, mips) which in theory can also use the same header.

2020-04-24Remove most gmp-mparam.h headers.Joseph Myers
Most gmp-mparam.h headers in glibc define various macros to the same values they would be defined to by the generic version of that header, plus macros IEEE_DOUBLE_BIG_ENDIAN or IEEE_DOUBLE_MIXED_ENDIAN related to the representation of double. The latter macros are in turn only used in gmp-impl.h to define union ieee_double_extract, which is not used in glibc. Thus all of these headers, except for the generic one and those that define _LONG_LONG_LIMB for ILP32 configurations with 64-bit registers, are redundant, and this patch removes them. Tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by this patch.

2020-03-19math: Remove inline math testsAdhemerval Zanella
With mathinline removal there is no need to keep building and testing inline math tests. The gen-libm-tests.py support to generate ULP_I_* is removed and all libm-test-ulps files are updated to longer have the i{float,double,ldouble} entries. The support for no-test-inline is also removed from both gen-auto-libm-tests and the auto-libm-test-out-* were regenerated. Checked on x86_64-linux-gnu and i686-linux-gnu.

2020-02-18Introduce <elf-initfini.h> and ELF_INITFINI for all architecturesFlorian Weimer
This supersedes the init_array sysdeps directory. It allows us to check for ELF_INITFINI in both C and assembler code, and skip DT_INIT and DT_FINI processing completely on newer architectures. A new header file is needed because <dl-machine.h> is incompatible with assembler code. <sysdep.h> is compatible with assembler code, but it cannot be included in all assembler files because on some architectures, it redefines register names, and some assembler files conflict with that. <elf-initfini.h> is replicated for legacy architectures which need DT_INIT/DT_FINI support. New architectures follow the generic default and disable it.
2020-01-03Add libm_alias_finite for _finite symbolsWilco Dijkstra
This patch adds a new macro, libm_alias_finite, to define all _finite symbol. It sets all _finite symbol as compat symbol based on its first version (obtained from the definition at built generated first-versions.h). The <fn>f128_finite symbols were introduced in GLIBC 2.26 and so need special treatment in code that is shared between long double and float128. It is done by adding a list, similar to internal symbol redifinition, on sysdeps/ieee754/float128/float128_private.h. Alpha also needs some tricky changes to ensure we still emit 2 compat symbols for sqrt(f). Passes buildmanyglibc.

2019-11-26nptl: Add default pthreadtypes-arch.hAdhemerval Zanella
This patch adds a default pthreadtypes-arch.h, the idea is to simpify new ports inclusion and an override is required only if the architecture adds some arch-specific extensions or requirement. The default values on the new generic header are based on current architecture define value and they are not optimal compared to current code requirements as below. - On 64 bits __SIZEOF_PTHREAD_BARRIER_T is defined as 32 while is sizeof (struct pthread_barrier) is 20 bytes. - On 32 bits __SIZEOF_PTHREAD_ATTR_T is defined as 36 while sizeof (struct pthread_attr) is 32. The default values are not changed so the generic header could be used by some architectures. Checked with a build on affected abis. Change-Id: Ie0cd586258a2650f715c1af0c9fe4e7063b0409a
2019-11-26nptl: Add struct_rwlock.hAdhemerval Zanella
This patch adds a new generic __pthread_rwlock_arch_t definition meant to be used by new ports. Its layout mimics the current usage on some 64 bits ports and it allows some ports to use the generic definition. The arch __pthread_rwlock_arch_t definition is moved from pthreadtypes-arch.h to another arch-specific header (struct_rwlock.h). Also the static intialization macro for pthread_rwlock_t is set to use an arch defined on (__PTHREAD_RWLOCK_INITIALIZER) which simplifies its implementation. The default pthread_rwlock_t layout differs from current ports with: 1. Internal layout is the same for 32 bits and 64 bits. 2. Internal flag is an unsigned short so it should not required additional padding to align for word boundary (if it is the case for the ABI). Checked with a build on affected abis.

2019-11-26nptl: Add struct_mutex.hAdhemerval Zanella
The current way of defining the common mutex definition for POSIX and C11 on pthreadtypes-arch.h (added by commit 06be6368da16104be5) is not really the best options for newer ports. It requires define some misleading flags that should be always defined as 0 (__PTHREAD_COMPAT_PADDING_MID and __PTHREAD_COMPAT_PADDING_END), it exposes options used solely for linuxthreads compat mode (__PTHREAD_MUTEX_USE_UNION and __PTHREAD_MUTEX_NUSERS_AFTER_KIND), and requires newer ports to explicit define them (adding more boilerplate code). This patch adds a new default __pthread_mutex_s definition meant to be used by newer ports. Its layout mimics the current usage on both 32 and 64 bits ports and it allows most ports to use the generic definition. Only ports that use some arch-specific definition (such as hardware lock-elision or linuxthreads compat) requires specific headers. For 32 bit, the generic definitions mimic the other 32-bit ports of using an union to define the fields uses on adaptive and robust mutexes (thus not allowing both usage at same time) and by using a single linked-list for robust mutexes. Both decisions seemed to follow what recent ports have done and make the resulting pthread_mutex_t/mtx_t object smaller. Also the static intialization macro for pthread_mutex_t is set to use a macro __PTHREAD_MUTEX_INITIALIZER where the architecture can redefine in its struct_mutex.h if it requires additional fields to be initialized.

2019-11-25arm: Fix armv7 selection after 'Split BE/LE abilist'Adhemerval Zanella
It adds the missing Implies for armv7, armv6, armv6t2 after the commit 1673ba87fefe019c. Without the Implies a build with the compiler targeting the aforementioned architecture does not select the arch-specific optimization including the ifunc selectors. I checked with a build against armv5, armv6, armv6t2, armv7, and armv7-neon for both LE and BE. For armv6 and armv7 I also checked that both sysdeps selection and the resulting implementation built is the expected ones.
2019-10-01Split up endian.h to minimize exposure of BYTE_ORDER.Alistair Francis
With only two exceptions (sys/types.h and sys/param.h, both of which historically might have defined BYTE_ORDER) the public headers that include <endian.h> only want to be able to test __BYTE_ORDER against __*_ENDIAN. This patch creates a new bits/endian.h that can be included by any header that wants to be able to test __BYTE_ORDER and/or __FLOAT_WORD_ORDER against the __*_ENDIAN constants, or needs __LONG_LONG_PAIR. It only defines macros in the implementation namespace. The existing bits/endian.h (which could not be included independently of endian.h, and only defines __BYTE_ORDER and maybe __FLOAT_WORD_ORDER) is renamed to bits/endianness.h. I also took the opportunity to canonicalize the form of this header, which we are stuck with having one copy of per architecture. Since they are so short, this means git doesn’t understand that they were renamed from existing headers, sigh. endian.h itself is a nonstandard header and its only remaining use from a standard header is guarded by __USE_MISC, so I dropped the __USE_MISC conditionals from around all of the public-namespace things it defines. (This means, an application that requests strict library conformance but includes endian.h will still see the definition of BYTE_ORDER.) A few changes to specific bits/endian(ness).h variants deserve mention: - sysdeps/unix/sysv/linux/ia64/bits/endian.h is moved to sysdeps/ia64/bits/endianness.h. If I remember correctly, ia64 did have selectable endianness, but we have assembly code in sysdeps/ia64 that assumes it’s little-endian, so there is no reason to treat the ia64 endianness.h as linux-specific. - The C-SKY port does not fully support big-endian mode, the compile will error out if __CSKYBE__ is defined. - The PowerPC port had extra logic in its bits/endian.h to detect a broken compiler, which strikes me as unnecessary, so I removed it. - The only files that defined __FLOAT_WORD_ORDER always defined it to the same value as __BYTE_ORDER, so I removed those definitions. The SH bits/endian(ness).h had comments inconsistent with the actual setting of __FLOAT_WORD_ORDER, which I also removed. - I *removed* copyright boilerplate from the few bits/endian(ness).h headers that had it; these files record a single fact in a fashion dictated by an external spec, so I do not think they are copyrightable. As long as I was changing every copy of ieee754.h in the tree, I noticed that only the MIPS variant includes float.h, because it uses LDBL_MANT_DIG to decide among three different versions of ieee854_long_double. This patch makes it not include float.h when GCC’s intrinsic __LDBL_MANT_DIG__ is available. * string/endian.h: Unconditionally define LITTLE_ENDIAN, BIG_ENDIAN, PDP_ENDIAN, and BYTE_ORDER.

2019-02-05arm: Use "nr" constraint for Systemtap probes [BZ #24164]Florian Weimer
With the default "nor" constraint, current GCC will use the "o" constraint for constants, after emitting the constant to memory. That results in unparseable Systemtap probe notes such as "-4@.L1052". Removing the "o" alternative and using "nr" instead avoids this.

2018-11-12Fix armv7 build with GCC 9.Joseph Myers
Similar to the x86_64 build issues, glibc fails to build for armv7 with current mainline GCC because of aliases declared in the course of defining IFUNCs, which copy their attributes from a header declaration, ending up with fewer attributes than the (built-in) string function they alias: the relevant attributes (nonnull, leaf) are present on the header declaration, but elided therefrom when glibc itself if being built (whatever the reasons are for disabling the nonnull and leaf attributes in that case, and whether or not those reasons are actually still valid). This patch fixes the issue similarly to the x86_64 fix, by adding an addition __attribute_copy__ use (in this case, on the definition of arm_libc_ifunc_hidden_def). Tested with build-many-glibcs.py build for armeb-linux-gnueabi-be8. * sysdeps/arm/arm-ifunc.h [SHARED] (arm_libc_ifunc_hidden_def): Use __attribute_copy__ to copy attributes from name.
2018-09-05Add new exp and exp2 implementationsSzabolcs Nagy
Optimized exp and exp2 implementations using a lookup table for fractional powers of 2. There are several variants, see e_exp_data.c, they can be selected by modifying math_config.h allowing different tradeoffs. The default selection should be acceptable as generic libm code. Worst case error is 0.509 ULP for exp and 0.507 ULP for exp2, on aarch64 the rodata size is 2160 bytes, shared between exp and exp2. On aarch64 .text + .rodata size decreased by 24912 bytes. The non-nearest rounding error is less than 1 ULP even on targets without efficient round implementation (although the error rate is higher in that case). Targets with single instruction, rounding mode independent, to nearest integer rounding and conversion can use them by setting TOINT_INTRINSICS and adding the necessary code to their math_private.h. The __exp1 code uses the same algorithm, so the error bound of pow increased a bit. New double precision error handling code was added following the style of the single precision error handling code. Improvements on Cortex-A72 compared to current glibc master: exp thruput: 1.61x in [-9.9 9.9] exp latency: 1.53x in [-9.9 9.9] exp thruput: 1.13x in [0.5 1] exp latency: 1.30x in [0.5 1] exp2 thruput: 2.03x in [-9.9 9.9] exp2 latency: 1.64x in [-9.9 9.9] For small (< 1) inputs the current exp code uses a separate algorithm so the speed up there is less. Was tested on aarch64-linux-gnu (TOINT_INTRINSICS, fma contraction) and arm-linux-gnueabihf (!TOINT_INTRINSICS, no fma contraction) and x86_64-linux-gnu (!TOINT_INTRINSICS, no fma contraction) and powerpc64le-linux-gnu (!TOINT_INTRINSICS, fma contraction) targets, only non-nearest rounding ulp errors increase and they are within acceptable bounds (ulp updates are in separate patches). * NEWS: Mention exp and exp2 improvements. * math/Makefile (libm-support): Remove t_exp.

2018-08-31[BZ #20271] Add newlines in __libc_fatal calls.Paul Pluzhnikov
2018-08-28Split fenv_private.h out of math_private.h more consistently.Joseph Myers
On some architectures, the parts of math_private.h relating to the floating-point environment are in a separate file fenv_private.h included from math_private.h. As this is purely an architecture-specific convention used by several architectures, however, all such architectures still need their own math_private.h, even if it has nothing to do beyond #include <fenv_private.h> and peculiarity of including the i386 file directly instead of having a shared file in sysdeps/x86. This patch makes the fenv_private.h name an architecture-independent convention in glibc. The include of fenv_private.h from math_private.h becomes architecture-independent (until callers are updated to include fenv_private.h directly so the include from math_private.h is no longer needed). Some architecture math_private.h headers are removed if no longer needed, or renamed to fenv_private.h if all they define belongs in that header; architecture fenv_private.h headers now do require #include_next <fenv_private.h>. The i386 fenv_private.h file moves to sysdeps/x86/fpu/ to reflect how it is actually shared with x86_64. The generic math_private.h gets a new include of <stdbool.h>, as needed for bool in some prototypes in that header (previously that was indirectly included via include/fenv.h, which now only gets included too late in math_private.h, after those prototypes). Tested for x86_64 and x86, and tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by the patch. * sysdeps/aarch64/fpu/fenv_private.h: New file.

Continuing moving macros out of math-tests.h to smaller headers following typo-proof conventions instead of using #ifndef, this patch moves the EXCEPTION_TESTS_* macros for individual types out to their own sysdeps header. As with ROUNDING_TESTS_*, there is no need to define these macros if FE_ALL_EXCEPT == 0 and the individual exception macros are undefined; thus, math-tests-exceptions.h headers are only needed for soft-float ARM and RISC-V, while the other cases that defined these macros do not need to do so (and the associated math-tests.h headers are thus removed without needing replacement by math-tests-exceptions.h headers).

2018-08-22Move ROUNDING_TESTS_* out of math-tests.h.Joseph Myers
Continuing moving macros out of math-tests.h to smaller headers following typo-proof conventions instead of using #ifndef, this patch moves the ROUNDING_TESTS_* macros for individual types out to their own sysdeps header. In the soft-float case where FE_TONEAREST is the only rounding mode macro defined, there is no need to define ROUNDING_TESTS_*; it is only necessary when rounding modes macros are defined that may not be supported at runtime. Thus, the ROUNDING_TESTS_* definitions for some configurations are just removed, not moved to new math-tests-rounding.h headers; the only architectures needing math-tests-rounding.h are those where the macros are defined in bits/fenv.h because of the possibility of a soft-float compilation using a hard-float glibc with the same ABI (i.e., ARM and RISC-V). The test-*-vlen*.h headers, by using #undef, do not yet follow typo-proof conventions (but they no longer implicitly rely on being included before math-tests.h, and this area can always be cleaned up further in future). Tested with build-many-glibcs.py. * sysdeps/generic/math-tests-rounding.h: New file. * sysdeps/generic/math-tests.h: Include <math-tests-rounding.h>. (ROUNDING_TESTS_float): Do not define here.

2018-04-04elf: Unify symbol address run-time calculation [BZ #19818]Maciej W. Rozycki
Wrap symbol address run-time calculation into a macro and use it throughout, replacing inline calculations. There are a couple of variants, most of them different in a functionally insignificant way. Most calculations are right following RESOLVE_MAP, at which point either the map or the symbol returned can be checked for validity as the macro sets either both or neither. In some places both the symbol and the map has to be checked however. My initial implementation therefore always checked both, however that resulted in code larger by as much as 0.3%, as many places know from elsewhere that no check is needed. I have decided the size growth was unacceptable. Having looked closer I realized that it's the map that is the culprit. Therefore I have modified LOOKUP_VALUE_ADDRESS to accept an additional boolean argument telling it to access the map without checking it for validity. This in turn has brought quite nice results, with new code actually being smaller for i686, and MIPS o32, n32 and little-endian n64 targets, unchanged in size for x86-64 and, unusually, marginally larger for big-endian MIPS n64, as follows: i686: text data bss dec hex filename 152255 4052 192 156499 26353 ld-2.27.9000-base.so 152159 4052 192 156403 262f3 ld-2.27.9000-elf-symbol-value.so MIPS/o32/el: text data bss dec hex filename 142906 4396 260 147562 2406a ld-2.27.9000-base.so 142890 4396 260 147546 2405a ld-2.27.9000-elf-symbol-value.so MIPS/n32/el: text data bss dec hex filename 142267 4404 260 146931 23df3 ld-2.27.9000-base.so 142171 4404 260 146835 23d93 ld-2.27.9000-elf-symbol-value.so MIPS/n64/el: text data bss dec hex filename 149835 7376 408 157619 267b3 ld-2.27.9000-base.so 149787 7376 408 157571 26783 ld-2.27.9000-elf-symbol-value.so MIPS/o32/eb: text data bss dec hex filename 142870 4396 260 147526 24046 ld-2.27.9000-base.so 142854 4396 260 147510 24036 ld-2.27.9000-elf-symbol-value.so MIPS/n32/eb: text data bss dec hex filename 142019 4404 260 146683 23cfb ld-2.27.9000-base.so 141923 4404 260 146587 23c9b ld-2.27.9000-elf-symbol-value.so MIPS/n64/eb: text data bss dec hex filename 149763 7376 408 157547 2676b ld-2.27.9000-base.so 149779 7376 408 157563 2677b ld-2.27.9000-elf-symbol-value.so x86-64: text data bss dec hex filename 148462 6452 400 155314 25eb2 ld-2.27.9000-base.so 148462 6452 400 155314 25eb2 ld-2.27.9000-elf-symbol-value.so [BZ #19818] * sysdeps/generic/ldsodefs.h (LOOKUP_VALUE_ADDRESS): Add `set' parameter.

2018-03-22Remove unused frame.h header, sigcontextinfo.h macros.Joseph Myers
The glibc-internal header frame.h was used in the old debug/backtrace.c but is now unused. Similarly, there are some sigcontextinfo.h macros that are used nowhere in glibc - ADVANCE_STACK_FRAME and FIRST_FRAME_POINTER were used in the old debug/backtrace.c, while SIGCONTEXT_EXTRA_ARGS, GET_FRAME, GET_STACK and CALL_SIGHANDLER were unused even before the removal of that old implementation (beyond uses of SIGCONTEXT_EXTRA_ARGS in definitions of CALL_SIGHANDLER).

2018-02-01Move LDBL_CLASSIFY_COMPAT to its own header.Joseph Myers
The general rule in glibc is that it's better for a macro to be always defined, and tested with #if, than for it to be tested with #ifdef, because the latter is prone to typos in the macro name as well as to the header with the macro accidentally not being included in a file testing it. (Testing with an "if" statement is even better, in those cases where it's possible to do things that way, as it then means both cases in the code get checked for syntax in glibc builds with either value of the condition.) math_private.h has several different groups of macros, meaning that architectures wanting to override some of them need to define those then include the generic version, which then defines macros if not already defined. It's hard to avoid that arrangement completely, but various cases can be improved by splitting out macros or groups of macros into separate files. This patch splits out the LDBL_CLASSIFY_COMPAT macro into a separate ldbl-classify-compat.h header. This macro is tested with #ifdef; this patch changes it to testing with #if, with a default definition to 0 in the generic header and then architecture-specific headers defining it to 1.

2017-12-12Add sysdeps/ieee754/soft-fp.Joseph Myers
The default sysdeps/ieee754 fma implementations rely on exceptions and rounding modes to achieve correct results through internal use of round-to-odd. Thus, glibc configurations without support for exceptions and rounding modes instead need to use implementations of fma based on soft-fp. At present, this is achieved via having implementation files in soft-fp/ that are #included by sysdeps files for each glibc configuration that needs them. In general this means such a configuration has its own s_fma.c and s_fmaf.c. TS 18661-1 adds functions that do an operation (+ - * / sqrt fma) on arguments wider than the return type, with a single rounding of the infinite-precision result to that return type. These are also naturally implemented using round-to-odd on platforms with hardware support for rounding modes and exceptions but lacking hardware support for these narrowing operations themselves. (Platforms that have direct hardware support for such narrowing operations include at least ia64, and Power ISA 2.07 or later, which I think means POWER8 or later.) So adding the remaining TS 18661-1 functions would mean at least six narrowing function implementations (fadd fsub fmul fdiv ffma fsqrt), with aliases for other types and further implementations in some configurations, that need to be overridden for configurations lacking hardware exceptions and rounding modes. Requiring all such configurations (currently seven of them) to have their own source files for all those functions seems undesirable. Thus, this patch adds a directory sysdeps/ieee754/soft-fp to contain libm function implementations based on soft-fp. This directory is then used via Implies from all the configurations that need it, so no more files need adding to every such configuration when adding more functions with soft-fp implementations. A configuration can still selectively #include a particular file from this directory if desired; thus, the MIPS #include of the fmal implementation is retained, since that's appropriate even for hard float (because long double is always implementated in software for MIPS64, so the soft-fp implementation of fmal is better than the ldbl-128 one). This also provides additional motivation for my recent patch removing --with-fp / --without-fp: previously there was no need for correct use of --without-fp for no-FPU ARM or SH3, and now we have autodetection nofpu/ sysdeps directories can be used by this patch for those configurations without imposing any new requirements on how glibc is configured. (The mips64/*/fpu/s_fma.c files added by this patch are needed to keep the dbl-64 version of fma for double, rather than the ldbl-128 one, used in that case.)

2017-11-07nptl: Define __PTHREAD_MUTEX_{NUSERS_AFTER_KIND,USE_UNION}Adhemerval Zanella
This patch adds two new internal defines to set the internal pthread_mutex_t layout required by the supported ABIS: 1. __PTHREAD_MUTEX_NUSERS_AFTER_KIND which control whether to define __nusers fields before or after __kind. The preferred value for is 0 for new ports and it sets __nusers before __kind. 2. __PTHREAD_MUTEX_USE_UNION which control whether internal __spins and __list members will be place inside an union for linuxthreads compatibility. The preferred value is 0 for ports and it sets to not use an union to define both fields. It fixes the wrong offsets value for __kind value on x86_64-linux-gnu-x32.
