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 <math.h> 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. |

Remove the error handling wrapper from log2
Introduce new log2 symbol version that doesn't do SVID compatible error handling.

Remove the error handling wrapper from exp and exp2
Introduce new exp and exp2 symbol version that don'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 double precision wrappers are disabled for sysdeps/ieee754/dbl-64 by using empty w_exp.c and w_exp2.c files, the math/w_exp.c and math/w_exp2.c files use the wrapper template and can be included by targets that have their own exp and exp2 implementations or use ifunc on the glibc internal __ieee754_exp symbol. The compatibility symbol versions still use 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 expl and exp2l were aliases of exp and exp2, now they point to the compatibility symbols with the wrapper, because they 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 _finite symbols are now aliases of the standard symbols (they have no performance advantage anymore). Both the standard symbols and _finite symbols 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 <math.h> was added before macro definitions that may affect that header (the new macro name is __exp instead of __ieee754_exp which breaks some math.h macros). Tested with build-many-glibcs.py. * math/Versions (GLIBC_2.29): Add exp and exp2. * math/w_exp2_compat.c (__exp2_compat): Change to versioned compat symbol, handle NO_LONG_DOUBLE and LONG_DOUBLE_COMPAT explicitly. * math/w_exp_compat.c (__exp_compat): Likewise. * math/w_exp.c: New file. * math/w_exp2.c: New file. * sysdeps/i386/fpu/w_exp.c: New file. * sysdeps/i386/fpu/w_exp2.c: New file. * sysdeps/ia64/fpu/e_exp.S: Add versioned symbols. * sysdeps/ia64/fpu/e_exp2.S: Likewise. * sysdeps/ieee754/dbl-64/e_exp.c (__ieee754_exp): Rename to __exp and add necessary aliases. * sysdeps/ieee754/dbl-64/e_exp2.c (__ieee754_exp2): Rename to __exp2 and add necessary aliases. * sysdeps/ieee754/dbl-64/w_exp.c: New file. * sysdeps/ieee754/dbl-64/w_exp2.c: New file. * sysdeps/m68k/m680x0/fpu/w_exp.c: New file. * sysdeps/m68k/m680x0/fpu/w_exp2.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_exp-avx.c (__exp1): Remove.

Add narrowing divide functions.
This patch adds the narrowing divide functions from TS 18661-1 to glibc's libm: fdiv, fdivl, ddivl, f32divf64, f32divf32x, f32xdivf64 for all configurations; f32divf64x, f32divf128, f64divf64x, f64divf128, f32xdivf64x, f32xdivf128, f64xdivf128 for configurations with _Float64x and _Float128; __nldbl_ddivl for ldbl-opt. The changes are mostly essentially the same as for the other narrowing functions, so the description of those generally applies to this patch as well. Tested for x86_64, x86, mips64 (all three ABIs, both hard and soft float) and powerpc, and with build-many-glibcs.py. * math/Makefile (libm-narrow-fns): Add div.

Add narrowing multiply functions.
This patch adds the narrowing multiply functions from TS 18661-1 to glibc's libm: fmul, fmull, dmull, f32mulf64, f32mulf32x, f32xmulf64 for all configurations; f32mulf64x, f32mulf128, f64mulf64x, f64mulf128, f32xmulf64x, f32xmulf128, f64xmulf128 for configurations with _Float64x and _Float128; __nldbl_dmull for ldbl-opt. The changes are mostly essentially the same as for the narrowing add functions, so the description of those generally applies to this patch as well. f32xmulf64 for i386 cannot use precision control as used for add and subtract, because that would result in double rounding for subnormal results, so that uses round-to-odd with long double intermediate result instead. The soft-fp support involves adding a new FP_TRUNC_COOKED since soft-fp multiplication uses cooked inputs and outputs. Tested for x86_64, x86, mips64 (all three ABIs, both hard and soft float) and powerpc, and with build-many-glibcs.py. * math/Makefile (libm-narrow-fns): Add mul. (libm-test-funcs-narrow): Likewise. * math/Versions (GLIBC_2.28): Add narrowing multiply functions. * math/bits/mathcalls-narrow.h (mul): Use __MATHCALL_NARROW. * math/gen-auto-libm-tests.c (test_functions): Add mul. * math/math-narrow.h (CHECK_NARROW_MUL): New macro.

Ignore absolute symbols in ABI tests.
A recent binutils patch <https://sourceware.org/ml/binutils/2018-04/msg00336.html> stops the MIPS linker including the _gp_disp absolute symbol in dynamic symbol tables. With older binutils, it is included for MIPS o32 (despite the use of symbol versioning), and this means that all the ABI test baselines for MIPS o32 include "_gp_disp _gp_disp A". This symbol is not meaningfully part of the ABI for shared libraries, since it always has to be resolved at static link time to the local definition for the linked object. All the other absolute symbols in ABI test baselines are the names of symbol versions. I don't think the mere existence of a symbol version with a given name - as opposed to the contents of that version if nonempty - is part of the ABI either. Thus, this patch allows the ABI tests to pass both before and after the binutils change by changing abilist.awk not to include absolute symbols in its output, and changing the baselines accordingly. Tested for x86_64, and with build-many-glibcs.py. * scripts/abilist.awk: Ignore absolute symbols. * sysdeps/mach/hurd/i386/ld.abilist: Remove absolute symbols. *

Add narrowing subtract functions.
This patch adds the narrowing subtract functions from TS 18661-1 to glibc's libm: fsub, fsubl, dsubl, f32subf64, f32subf32x, f32xsubf64 for all configurations; f32subf64x, f32subf128, f64subf64x, f64subf128, f32xsubf64x, f32xsubf128, f64xsubf128 for configurations with _Float64x and _Float128; __nldbl_dsubl for ldbl-opt. The changes are essentially the same as for the narrowing add functions, so the description of those generally applies to this patch as well.

Add narrowing add functions.
This patch adds the narrowing add functions from TS 18661-1 to glibc's libm: fadd, faddl, daddl, f32addf64, f32addf32x, f32xaddf64 for all configurations; f32addf64x, f32addf128, f64addf64x, f64addf128, f32xaddf64x, f32xaddf128, f64xaddf128 for configurations with _Float64x and _Float128; __nldbl_daddl for ldbl-opt. As discussed for the build infrastructure patch, tgmath.h support is deliberately deferred, and FP_FAST_* macros are not applicable without optimized function implementations. Function implementations are added for all relevant pairs of formats (including certain cases of a format and itself where more than one type has that format). The main implementations use round-to-odd, or a trivial computation in the case where both formats are the same or where the wider format is IBM long double (in which case we don't attempt to be correctly rounding). The sysdeps/ieee754/soft-fp implementations use soft-fp, and are used automatically for configurations without exceptions and rounding modes by virtue of existing Implies files. As previously discussed, optimized versions for particular architectures are possible, but not included. i386 gets a special version of f32xaddf64 to avoid problems with double rounding (similar to the existing fdim version), since this function must round just once without an intermediate rounding to long double. (No such special version is needed for any other function, because the nontrivial functions use round-to-odd, which does the intermediate computation with the rounding mode set to round-to-zero, and double rounding is OK except in round-to-nearest mode, so is OK for that intermediate round-to-zero computation.) mul and div will need slightly different special versions for i386 (using round-to-odd on long double instead of precision control) because of the possibility of inexact intermediate results in the subnormal range for double. To reduce duplication among the different function implementations, math-narrow.h gets macros CHECK_NARROW_ADD, NARROW_ADD_ROUND_TO_ODD and NARROW_ADD_TRIVIAL. In the trivial cases and for any architecture-specific optimized implementations, the overhead of the errno setting might be significant, but I think that's best handled through compiler built-in functions rather than providing separate no-errno versions in glibc (and likewise there are no __*_finite entry points for these function provided, __*_finite effectively being no-errno versions at present in most cases). Tested for x86_64 and x86, with both GCC 6 and GCC 7. Tested for mips64 (all three ABIs, both hard and soft float) and powerpc with GCC 7. Tested with build-many-glibcs.py with both GCC 6 and GCC 7. * math/Makefile (libm-narrow-fns): Add add.
