2024-01-08Remove ia64-linux-gnuAdhemerval Zanella378-140886/+0
Linux 6.7 removed ia64 from the official tree [1], following the general principle that a glibc port needs upstream support for the architecture in all the components it depends on (binutils, GCC, and the Linux kernel). Apart from the removal of sysdeps/ia64 and sysdeps/unix/sysv/linux/ia64, there are updates to various comments referencing ia64 for which removal of those references seemed appropriate. The configuration is removed from README and build-many-glibcs.py. The CONTRIBUTED-BY, elf/elf.h, manual/contrib.texi (the porting mention), *.po files, config.guess, and longlong.h are not changed. For Linux it allows cleanup some clone2 support on multiple files. The following bug can be closed as WONTFIX: BZ 22634 [2], BZ 14250 [3], BZ 21634 [4], BZ 10163 [5], BZ 16401 [6], and BZ 11585 [7].

2022-12-19stdio-common: Convert vfprintf and related functions to buffersFlorian Weimer1-7/+1
vfprintf is entangled with vfwprintf (of course), __printf_fp, __printf_fphex, __vstrfmon_l_internal, and the strfrom family of functions. The latter use the internal snprintf functionality, so vsnprintf is converted as well. The simples conversion is __printf_fphex, followed by __vstrfmon_l_internal and __printf_fp, and finally __vfprintf_internal and __vfwprintf_internal. __vsnprintf_internal and strfrom* are mostly consuming the new interfaces, so they are comparatively simple. __printf_fp is a public symbol, so the FILE *-based interface had to preserved. The __printf_fp rewrite does not change the actual binary-to-decimal conversion algorithm, and digits are still not emitted directly to the target buffer. However, the staging buffer now uses bytes instead of wide characters, and one buffer copy is eliminated. The changes are at least performance-neutral in my testing. Floating point printing and snprintf improved measurably, so that this Lua script for i=1,5000000 do print(i, i * math.pi) end runs about 5% faster for me. To preserve fprintf performance for a simple "%d" format, this commit has some logic changes under LABEL (unsigned_number) to avoid additional function calls. There are certainly some very easy performance improvements here: binary, octal and hexadecimal formatting can easily avoid the temporary work buffer (the number of digits can be computed ahead-of-time using one of the __builtin_clz* built-ins). Decimal formatting can use a specialized version of _itoa_word for base 10. The existing (inconsistent) width handling between strfmon and printf is preserved here. __print_fp_buffer_1 would have to use __translated_number_width to achieve ISO conformance for printf. Test expectations in libio/tst-vtables-common.c are adjusted because the internal staging buffer merges all virtual function calls into one. In general, stack buffer usage is greatly reduced, particularly for unbuffered input streams. __printf_fp can still use a large buffer in binary128 mode for %g, though.

2022-05-23math: Add math-use-builtins-fabs (BZ#29027)Adhemerval Zanella1-82/+0
Both float, double, and _Float128 are assumed to be supported (float and double already only uses builtins). Only long double is parametrized due GCC bug 29253 which prevents its usage on powerpc. It allows to remove i686, ia64, x86_64, powerpc, and sparc arch specific implementation. On ia64 it also fixes the sNAN handling: math/test-float64x-fabs math/test-ldouble-fabs Checked on x86_64-linux-gnu, i686-linux-gnu, powerpc-linux-gnu, powerpc64-linux-gnu, sparc64-linux-gnu, and ia64-linux-gnu.

2021-09-22Add narrowing fma functionsJoseph Myers2-0/+2
This patch adds the narrowing fused multiply-add functions from TS 18661-1 / TS 18661-3 / C2X to glibc's libm: ffma, ffmal, dfmal, f32fmaf64, f32fmaf32x, f32xfmaf64 for all configurations; f32fmaf64x, f32fmaf128, f64fmaf64x, f64fmaf128, f32xfmaf64x, f32xfmaf128, f64xfmaf128 for configurations with _Float64x and _Float128; __f32fmaieee128 and __f64fmaieee128 aliases in the powerpc64le case (for calls to ffmal and dfmal when long double is IEEE binary128). Corresponding tgmath.h macro support is also added. The changes are mostly similar to those for the other narrowing functions previously added, especially that for sqrt, so the description of those generally applies to this patch as well. As with sqrt, I reused the same test inputs in auto-libm-test-in as for non-narrowing fma rather than adding extra or separate inputs for narrowing fma. The tests in libm-test-narrow-fma.inc also follow those for non-narrowing fma. The non-narrowing fma has a known bug (bug 6801) that it does not set errno on errors (overflow, underflow, Inf * 0, Inf - Inf). Rather than fixing this or having narrowing fma check for errors when non-narrowing does not (complicating the cases when narrowing fma can otherwise be an alias for a non-narrowing function), this patch does not attempt to check for errors from narrowing fma and set errno; the CHECK_NARROW_FMA macro is still present, but as a placeholder that does nothing, and this missing errno setting is considered to be covered by the existing bug rather than needing a separate open bug. missing-errno annotations are duly added to many of the auto-libm-test-in test inputs for fma. This completes adding all the new functions from TS 18661-1 to glibc, so will be followed by corresponding stdc-predef.h changes to define __STDC_IEC_60559_BFP__ and __STDC_IEC_60559_COMPLEX__, as the support for TS 18661-1 will be at a similar level to that for C standard floating-point facilities up to C11 (pragmas not implemented, but library functions done). (There are still further changes to be done to implement changes to the types of fromfp functions from N2548.) Tested as followed: natively with the full glibc testsuite for x86_64 (GCC 11, 7, 6) and x86 (GCC 11); with build-many-glibcs.py with GCC 11, 7 and 6; cross testing of math/ tests for powerpc64le, powerpc32 hard float, mips64 (all three ABIs, both hard and soft float). The different GCC versions are to cover the different cases in tgmath.h and tgmath.h tests properly (GCC 6 has _Float* only as typedefs in glibc headers, GCC 7 has proper _Float* support, GCC 8 adds __builtin_tgmath).
2021-09-10Add narrowing square root functionsJoseph Myers2-0/+2
This patch adds the narrowing square root functions from TS 18661-1 / TS 18661-3 / C2X to glibc's libm: fsqrt, fsqrtl, dsqrtl, f32sqrtf64, f32sqrtf32x, f32xsqrtf64 for all configurations; f32sqrtf64x, f32sqrtf128, f64sqrtf64x, f64sqrtf128, f32xsqrtf64x, f32xsqrtf128, f64xsqrtf128 for configurations with _Float64x and _Float128; __f32sqrtieee128 and __f64sqrtieee128 aliases in the powerpc64le case (for calls to fsqrtl and dsqrtl when long double is IEEE binary128). Corresponding tgmath.h macro support is also added. The changes are mostly similar to those for the other narrowing functions previously added, so the description of those generally applies to this patch as well. However, the not-actually-narrowing cases (where the two types involved in the function have the same floating-point format) are aliased to sqrt, sqrtl or sqrtf128 rather than needing a separately built not-actually-narrowing function such as was needed for add / sub / mul / div. Thus, there is no __nldbl_dsqrtl name for ldbl-opt because no such name was needed (whereas the other functions needed such a name since the only other name for that entry point was e.g. f32xaddf64, not reserved by TS 18661-1); the headers are made to arrange for sqrt to be called in that case instead. The DIAG_* calls in sysdeps/ieee754/soft-fp/s_dsqrtl.c are because they were observed to be needed in GCC 7 testing of riscv32-linux-gnu-rv32imac-ilp32. The other sysdeps/ieee754/soft-fp/ files added didn't need such DIAG_* in any configuration I tested with build-many-glibcs.py, but if they do turn out to be needed in more files with some other configuration / GCC version, they can always be added there. I reused the same test inputs in auto-libm-test-in as for non-narrowing sqrt rather than adding extra or separate inputs for narrowing sqrt. The tests in libm-test-narrow-sqrt.inc also follow those for non-narrowing sqrt. Tested as followed: natively with the full glibc testsuite for x86_64 (GCC 11, 7, 6) and x86 (GCC 11); with build-many-glibcs.py with GCC 11, 7 and 6; cross testing of math/ tests for powerpc64le, powerpc32 hard float, mips64 (all three ABIs, both hard and soft float). The different GCC versions are to cover the different cases in tgmath.h and tgmath.h tests properly (GCC 6 has _Float* only as typedefs in glibc headers, GCC 7 has proper _Float* support, GCC 8 adds __builtin_tgmath).
2021-09-03Remove "Contributed by" linesSiddhesh Poyarekar191-196/+0
We stopped adding "Contributed by" or similar lines in sources in 2012 in favour of git logs and keeping the Contributors section of the glibc manual up to date. Removing these lines makes the license header a bit more consistent across files and also removes the possibility of error in attribution when license blocks or files are copied across since the contributed-by lines don't actually reflect reality in those cases. Move all "Contributed by" and similar lines (Written by, Test by, etc.) into a new file CONTRIBUTED-BY to retain record of these contributions. These contributors are also mentioned in manual/contrib.texi, so we just maintain this additional record as a courtesy to the earlier developers. The following scripts were used to filter a list of files to edit in place and to clean up the CONTRIBUTED-BY file respectively. These were not added to the glibc sources because they're not expected to be of any use in future given that this is a one time task: https://gist.github.com/siddhesh/b5ecac94eabfd72ed2916d6d8157e7dc https://gist.github.com/siddhesh/15ea1f5e435ace9774f485030695ee02 Reviewed-by: Carlos O'Donell <carlos@redhat.com>

2020-06-19ia64: Use generic exp10fAdhemerval Zanella7-572/+8
The generic implementation is slight worse (Itanium(R) Processor 9020): Before new code: "exp10f": { "workload-spec2017.wrf (adapted)": { "duration": 3.61582e+08, "iterations": 2.384e+07, "reciprocal-throughput": 14.8334, "latency": 15.5006, "max-throughput": 6.74153e+07, "min-throughput": 6.45136e+07 } } With new code: "exp10f": { "workload-spec2017.wrf (adapted)": { "duration": 3.85549e+08, "iterations": 2.384e+07, "reciprocal-throughput": 15.8391, "latency": 16.5056, "max-throughput": 6.31348e+07, "min-throughput": 6.05857e+07 } } However it fixes all the issues on both: math/test-float-exp10 math/test-float32-exp10 (all the issues wrong results for non default rounding modes). The existing ia64 libm interface uses matherrf and matherrl in addition to matherr for SVID error handling. However, there is no such error handling support for exp10f in ia64 libm. So replacing it with the generic implementation should be fine. Checked on ia64-linux-gnu.
2020-06-19New exp10f version without SVID compat wrapperAdhemerval Zanella1-3/+9
This patch changes the exp10f error handling semantics to only set errno according to POSIX rules. New symbol version is introduced at GLIBC_2.32. The old wrappers are kept for compat symbols. There are some outliers that need special handling: - ia64 provides an optimized implementation of exp10f that uses ia64 specific routines to set SVID compatibility. The new symbol version is aliased to the exp10f one. - m68k also provides an optimized implementation, and the new version uses it instead of the sysdeps/ieee754/flt32 one. - riscv and csky uses the generic template implementation that does not provide SVID support. For both cases a new exp10f version is not added, but rather the symbols version of the generic sysdeps/ieee754/flt32 is adjusted instead. Checked on aarch64-linux-gnu, x86_64-linux-gnu, i686-linux-gnu, powerpc64le-linux-gnu.

2018-11-21Remove the error handling wrapper from powSzabolcs Nagy1-3/+9
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.

2018-11-21Remove the error handling wrapper from log2Szabolcs Nagy1-3/+9
Introduce new log2 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_log2.c and enabled for targets with their own log2 implementation by including math/w_log2.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).
