b2969efa - Use a builtin where possible in msun

Tue, 02 Nov 2021 11:31:17 +0000

Use a builtin where possible in msunSome of the functions in msun can be implemented using a compilerbuiltin function to generate a small number of instructions. Implementthis support in fma, fmax, fmin, and sqrt on arm64.Care must be taken as the builtin can be implemented as a functioncall on some architectures that lack direct support. In these caseswe need to use the original code path.As we don't set errno on failure build with -fno-math-errno so thetoolchain doesn't convert a builtin into a function call when itdetects a failure, e.g. gcc will add a call to sqrt when the inputis negative leading to an infinite loop.Sponsored by: The FreeBSD FoundationDifferential Revision: https://reviews.freebsd.org/D32801(cherry picked from commit b2e843161dc3b79777e873183447c92ed9c3703a) List of files: /freebsd-13.1/lib/msun/Makefile

lib/msun: Exclude ignored-pragmas from -WerrorThis avoids build failures due to the clang 12 warning: '#pragma FENV_ACCESS' is not supported on this target - ignoredClang 12 currently emits this warning for all non-x86 architectures.While this can result in incorrect code generation (e.g. on AArch64 someexceptions are not raised as expected), this is a pre-existing issue andwe should not fail the build due to this warning.Reviewed By: dim, emasteMFC after: 1 weekDifferential Revision: https://reviews.freebsd.org/D29743(cherry picked from commit 168234fa67c38f898b784b3265dd77ace0b0a2f9) List of files: /freebsd-13.1/lib/msun/Makefile

bda3bf09 - Avoid raising unexpected floating point exceptions in libm

Fri, 09 Apr 2021 23:07:54 +0000

Avoid raising unexpected floating point exceptions in libmWhen using clang with x86_64 CPUs that support AVX, some floating pointtransformations may raise exceptions that would not have been raised bythe original code. To avoid this, use the -fp-exception-behavior=maytrapflag, introduced in clang 10.0.0.In particular, this fixes a number of test failures with ctanhf(3) andctanf(3), when libm is compiled with -mavx. An unexpected FE_INVALIDexception is then raised, because clang emits vdivps instructions toperform certain divides. (The vdivps instruction operates on multiplesingle-precision float operands simultaneously, but the exceptions maybe influenced by unused parts of the XMM registers. In this particularcase, it was calculating 0 / 0, which results in FE_INVALID.)If -fp-exception-behavior=maytrap is specified however, clang usesvdivss instructions instead, which work on one operand, and should notraise unexpected exceptions.Reported by: olivierReviewed by: arichardsonPR: 254911Differential Revision: https://reviews.freebsd.org/D29686(cherry picked from commit 3b00222f156dca5700c839d73e36daf479fa640c)Only use -fp-exception-behavior=maytrap on x86, for nowAfter 3b00222f156d, it turns out that clang only supports strictfloating point semantics for SystemZ and x86 at the moment, while forother architectures it is still experimental.Therefore, only use -fp-exception-behavior=maytrap on x86 for now,otherwise this option results in "error: overriding currentlyunsupported use of floating point exceptions on this target[-Werror,-Wunsupported-floating-point-opt]" on other architectures.Fixes: 3b00222f156dPR: 254911(cherry picked from commit bae9fd0b33462e9506c3ac3400089c6dbc4aee8f) List of files: /freebsd-13.1/lib/msun/Makefile
