From: Szabolcs Nagy Date: Wed, 27 Jun 2018 15:33:16 +0000 (+0100) Subject: Remove the error handling wrapper from pow X-Git-Tag: upstream/2.30~700 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a502c5294b46109827c970a989ee10d1a9dcb176;p=platform%2Fupstream%2Fglibc.git Remove the error handling wrapper from pow Introduce new pow symbol version that doesn't do SVID compatible error handling. The standard errno and fp exception based error handling is inline in the new code and does not have significant overhead. The wrapper is disabled for sysdeps/ieee754/dbl-64 by using empty w_pow.c and enabled for targets with their own pow implementation or ifunc dispatch on __ieee754_pow by including math/w_pow.c. The compatibility symbol version still uses the wrapper with SVID error handling around the new code. There is no new symbol version nor compatibility code on !LIBM_SVID_COMPAT targets (e.g. riscv). On targets where previously powl was an alias of pow, now it points to the compatibility symbol with the wrapper, because it still need the SVID compatible error handling. This affects NO_LONG_DOUBLE (e.g. arm) and LONG_DOUBLE_COMPAT (e.g. alpha) targets as well. The __pow_finite symbol is now an alias of pow. Both __pow_finite and pow set errno and thus not const functions. The ia64 asm is changed so the compat and new symbol versions map to the same address. On x86_64 #include was added before macro definitions that may affect that header. Tested with build-many-glibcs.py. * math/Versions (GLIBC_2.29): Add pow. * math/w_pow_compat.c (__pow_compat): Change to versioned compat symbol. * math/w_pow.c: New file. * sysdeps/i386/fpu/w_pow.c: New file. * sysdeps/ia64/fpu/e_pow.S: Add versioned symbols. * sysdeps/ieee754/dbl-64/e_pow.c (__ieee754_pow): Rename to __pow and add necessary aliases. * sysdeps/ieee754/dbl-64/w_pow.c: New file. * sysdeps/m68k/m680x0/fpu/w_pow.c: New file. * sysdeps/mach/hurd/i386/libm.abilist: Update. * sysdeps/unix/sysv/linux/aarch64/libm.abilist: Update. * sysdeps/unix/sysv/linux/alpha/libm.abilist: Update. * sysdeps/unix/sysv/linux/arm/libm.abilist: Update. * sysdeps/unix/sysv/linux/hppa/libm.abilist: Update. * sysdeps/unix/sysv/linux/i386/libm.abilist: Update. * sysdeps/unix/sysv/linux/ia64/libm.abilist: Update. * sysdeps/unix/sysv/linux/m68k/coldfire/libm.abilist: Update. * sysdeps/unix/sysv/linux/m68k/m680x0/libm.abilist: Update. * sysdeps/unix/sysv/linux/microblaze/libm.abilist: Update. * sysdeps/unix/sysv/linux/mips/mips32/libm.abilist: Update. * sysdeps/unix/sysv/linux/mips/mips64/libm.abilist: Update. * sysdeps/unix/sysv/linux/nios2/libm.abilist: Update. * sysdeps/unix/sysv/linux/powerpc/powerpc32/fpu/libm.abilist: Update. * sysdeps/unix/sysv/linux/powerpc/powerpc32/nofpu/libm.abilist: Update. * sysdeps/unix/sysv/linux/powerpc/powerpc64/libm-le.abilist: Update. * sysdeps/unix/sysv/linux/powerpc/powerpc64/libm.abilist: Update. * sysdeps/unix/sysv/linux/s390/s390-32/libm.abilist: Update. * sysdeps/unix/sysv/linux/s390/s390-64/libm.abilist: Update. * sysdeps/unix/sysv/linux/sh/libm.abilist: Update. * sysdeps/unix/sysv/linux/sparc/sparc32/libm.abilist: Update. * sysdeps/unix/sysv/linux/sparc/sparc64/libm.abilist: Update. * sysdeps/unix/sysv/linux/x86_64/64/libm.abilist: Update. * sysdeps/unix/sysv/linux/x86_64/x32/libm.abilist: Update. * sysdeps/x86_64/fpu/multiarch/e_pow-fma.c (__ieee754_pow): Rename to __pow. * sysdeps/x86_64/fpu/multiarch/e_pow-fma4.c (__ieee754_pow): Likewise. * sysdeps/x86_64/fpu/multiarch/e_pow.c (__ieee754_pow): Likewise. * sysdeps/x86_64/fpu/multiarch/w_pow.c: New file. --- diff --git a/ChangeLog b/ChangeLog index 94d0b97..f1db5d3 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,5 +1,47 @@ 2018-11-21 Szabolcs Nagy + * math/Versions (GLIBC_2.29): Add pow. + * math/w_pow_compat.c (__pow_compat): Change to versioned compat + symbol. + * math/w_pow.c: New file. + * sysdeps/i386/fpu/w_pow.c: New file. + * sysdeps/ia64/fpu/e_pow.S: Add versioned symbols. + * sysdeps/ieee754/dbl-64/e_pow.c (__ieee754_pow): Rename to __pow + and add necessary aliases. + * sysdeps/ieee754/dbl-64/w_pow.c: New file. + * sysdeps/m68k/m680x0/fpu/w_pow.c: New file. + * sysdeps/mach/hurd/i386/libm.abilist: Update. + * sysdeps/unix/sysv/linux/aarch64/libm.abilist: Update. + * sysdeps/unix/sysv/linux/alpha/libm.abilist: Update. + * sysdeps/unix/sysv/linux/arm/libm.abilist: Update. + * sysdeps/unix/sysv/linux/hppa/libm.abilist: Update. + * sysdeps/unix/sysv/linux/i386/libm.abilist: Update. + * sysdeps/unix/sysv/linux/ia64/libm.abilist: Update. + * sysdeps/unix/sysv/linux/m68k/coldfire/libm.abilist: Update. + * sysdeps/unix/sysv/linux/m68k/m680x0/libm.abilist: Update. + * sysdeps/unix/sysv/linux/microblaze/libm.abilist: Update. + * sysdeps/unix/sysv/linux/mips/mips32/libm.abilist: Update. + * sysdeps/unix/sysv/linux/mips/mips64/libm.abilist: Update. + * sysdeps/unix/sysv/linux/nios2/libm.abilist: Update. + * sysdeps/unix/sysv/linux/powerpc/powerpc32/fpu/libm.abilist: Update. + * sysdeps/unix/sysv/linux/powerpc/powerpc32/nofpu/libm.abilist: Update. + * sysdeps/unix/sysv/linux/powerpc/powerpc64/libm-le.abilist: Update. + * sysdeps/unix/sysv/linux/powerpc/powerpc64/libm.abilist: Update. + * sysdeps/unix/sysv/linux/s390/s390-32/libm.abilist: Update. + * sysdeps/unix/sysv/linux/s390/s390-64/libm.abilist: Update. + * sysdeps/unix/sysv/linux/sh/libm.abilist: Update. + * sysdeps/unix/sysv/linux/sparc/sparc32/libm.abilist: Update. + * sysdeps/unix/sysv/linux/sparc/sparc64/libm.abilist: Update. + * sysdeps/unix/sysv/linux/x86_64/64/libm.abilist: Update. + * sysdeps/unix/sysv/linux/x86_64/x32/libm.abilist: Update. + * sysdeps/x86_64/fpu/multiarch/e_pow-fma.c (__ieee754_pow): Rename to + __pow. + * sysdeps/x86_64/fpu/multiarch/e_pow-fma4.c (__ieee754_pow): Likewise. + * sysdeps/x86_64/fpu/multiarch/e_pow.c (__ieee754_pow): Likewise. + * sysdeps/x86_64/fpu/multiarch/w_pow.c: New file. + +2018-11-21 Szabolcs Nagy + * math/Versions (GLIBC_2.29): Add log2. * math/w_log2_compat.c (__log2_compat): Change to versioned compat symbol. diff --git a/math/Versions b/math/Versions index a887602..f1ab297 100644 --- a/math/Versions +++ b/math/Versions @@ -577,6 +577,6 @@ libm { } GLIBC_2.29 { # No SVID compatible error handling. - exp;
