I used these shell commands: ../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright (cd ../glibc && git commit -am"[this commit message]") and then ignored the output, which consisted lines saying "FOO: warning: copyright statement not found" for each of 7061 files FOO. I then removed trailing white space from math/tgmath.h, support/tst-support-open-dev-null-range.c, and sysdeps/x86_64/multiarch/strlen-vec.S, to work around the following obscure pre-commit check failure diagnostics from Savannah.

2020-01-03Add libm_alias_finite for _finite symbolsWilco Dijkstra1-2/+2
This patch adds a new macro, libm_alias_finite, to define all _finite symbol. It sets all _finite symbol as compat symbol based on its first version (obtained from the definition at built generated first-versions.h). The <fn>f128_finite symbols were introduced in GLIBC 2.26 and so need special treatment in code that is shared between long double and float128. It is done by adding a list, similar to internal symbol redifinition, on sysdeps/ieee754/float128/float128_private.h. Alpha also needs some tricky changes to ensure we still emit 2 compat symbols for sqrt(f). Passes buildmanyglibc.

2018-11-12Fix i686 build with GCC 9.Joseph Myers1-1/+1
This patch fixes the glibc build for i686 with current mainline GCC, where there are warnings about inconsistent attributes for aliases in certain files defining libm IFUNCs. In three of the files, the aliases were defined in terms of internal symbols such as __sinf, and copied attributes from file-local declarations of those functions which lacked the nothrow attribute. Since the nothrow attribute is present on the declarations from <math.h> (which include declarations of those __-prefixed functions), the natural fix was to include <math.h> in those files, replacing the local declarations. In the other three files, a more complicated __hidden_ver1 call was involved in the warnings. <math.h> has not been included at this point and, furthermore, it is included indirectly only later in the source file after macros have been defined to remap a function name therein. So there isn't an obvious declaration from which to copy the attribute and it seems simplest and safest just to add __THROW to the hidden_ver1 calls. Tested for i686 (build-many-glibcs.py compilers build for x86_64-linux-gnu with GCC mainline; full testsuite run with GCC 7). * sysdeps/i386/i686/fpu/multiarch/e_expf.c [SHARED]: Use __THROW with __hidden_ver1 call. * sysdeps/i386/i686/fpu/multiarch/e_log2f.c [SHARED]: Likewise. * sysdeps/i386/i686/fpu/multiarch/e_logf.c [SHARED]: Likewise. * sysdeps/i386/i686/fpu/multiarch/s_cosf.c: Include <math.h>.

2017-11-29Use libm_alias_float for i386.Joseph Myers1-1/+3
Continuing the preparation for additional _FloatN / _FloatNx function aliases, this patch makes i386 libm function implementations use libm_alias_float (or libm_alias_float_other in cases where the main symbol name is defined with versioned_symbol) to define function aliases.
