2015-03-10soft-fp: Use multiple-include guards.Joseph Myers
This patch makes soft-fp headers consistently use multiple-include guards, something previously done mainly only in the Linux kernel version. The guard macros aren't the same as those used in the Linux kernel, but there seems to be enough variation in such guards in Linux kernel code that hopefully this version will be acceptable there. Tested for powerpc-nofpu that installed stripped shared libraries are unchanged by this patch. * soft-fp/double.h [SOFT_FP_DOUBLE_H]: New multiple-include guard. * soft-fp/extended.h [SOFT_FP_EXTENDED_H]: Likewise. * soft-fp/op-1.h [SOFT_FP_OP_1_H]: Likewise. * soft-fp/op-2.h [SOFT_FP_OP_2_H]: Likewise. * soft-fp/op-4.h [SOFT_FP_OP_4_H]: Likewise. * soft-fp/op-8.h [SOFT_FP_OP_8_H]: Likewise. * soft-fp/op-common.h [SOFT_FP_OP_COMMON_H]: Likewise. * soft-fp/quad.h [SOFT_FP_QUAD_H]: Likewise. * soft-fp/single.h [SOFT_FP_SINGLE_H]: Likewise. * soft-fp/soft-fp.h (SOFT_FP_H): Define to 1 rather than empty.

2014-11-04soft-fp: Add _FP_TO_INT_ROUND.Joseph Myers
Continuing the series of patches adding soft-fp features from the kernel version of soft-fp to glibc so that glibc's version is able to replace the old fork of soft-fp in the kernel, this patch adds the last major such feature: _FP_TO_INT_ROUND, converting a floating-point number to an integer with rounding according to the current rounding direction (as opposed to truncating towards zero, which _FP_TO_INT does). The general structure of the implementation follows that of _FP_TO_INT, but of course is more complicated. As with glibc's _FP_TO_INT it works with raw input (the kernel versions of these macros predate the conversion of _FP_TO_INT and many other macros to raw or semi-raw input). I have not tried to work out what bugs there might be in the kernel version that this might fix; it's a from-scratch implementation based on _FP_TO_INT. Tested for powerpc (soft-float) that there is no change to the installed shared libraries; also tested with the libm tests with lrint / lrintf / llrint / llrintf made to use _FP_TO_INT_ROUND, to provide some test of the functionality. As we don't have benchmarks for those functions, I haven't actually included the soft-fp versions of them, although I expect them to be faster than the existing code (given that the existing code involves adding and subtracting numbers such as 0x1p52 to achieve the desired rounding, which is not particularly efficient when the underlying floating point is software floating point). 2014-11-04 Joseph Myers <joseph@codesourcery.com> * soft-fp/op-common.h (_FP_TO_INT_ROUND): New macro. * soft-fp/double.h [_FP_W_TYPE_SIZE < 64] (FP_TO_INT_ROUND_D): New macro.

2014-10-09soft-fp: Use parentheses around macro arguments.Joseph Myers
This patch cleans up the soft-fp code to use parentheses around macro arguments (where possible; many macro arguments are identifiers used with ## rather than arbitrary expressions, so cannot be put in parentheses). (I'm not aware of any bugs caused by the lack of parentheses, but this is generally good practice. The patch is not exhaustive regarding internal macros where the arguments always come directly from the mantissa of a floating-point number, although probably those should be cleaned up in this regard as well.) Tested for powerpc-nofpu that the installed shared libraries are unchanged by this patch. * soft-fp/double.h [_FP_W_TYPE_SIZE < 64] (FP_UNPACK_RAW_D): Use parentheses around macro arguments.

2014-10-09soft-fp: Refactor exception handling for comparisons.Joseph Myers
This patch refactors how soft-fp comparisons handle setting exceptions for NaN operands, so that exceptions are set through the FP_CMP macros rather than directly in the C files calling them. The _FP_CMP* and FP_CMP* macros gain an extra argument to specify when exceptions should be set, 0 for no exception setting (I'm not sure this is actually needed - at least it's not needed for IEEE operations in glibc / libgcc, but might be relevant in some cases for kernel use), 1 for exceptions only for signaling NaNs and 2 for exceptions for all NaNs. This argument is handled through _FP_CMP_CHECK_NAN, newly called by the _FP_CMP* macros when a NaN is encountered. Calls to these macros are updated, which eliminates all the existing checking and exception setting in soft-fp *.c files in glibc. Tested for powerpc-nofpu. (The __unord* functions have no code changes; the __eq* / __ge* / __le* functions get slightly larger, but I don't think that's significant.) * soft-fp/op-common.h (_FP_CMP_CHECK_NAN): New macro.
