Continuing the fixes for C90 libm functions calling C99 fe* functions, this patch fixes the case of feholdexcept by making it a weak alias of __feholdexcept and making the affected code call __feholdexcept. Tested for x86_64 (testsuite, and that disassembly of installed shared libraries is unchanged by the patch). Also tested for ARM (soft-float) that feholdexcept failures disappear from the linknamespace test failures (fesetenv, fsetround and feupdateenv remain to be addressed to complete fixing bug 17748). [BZ #17748] * include/fenv.h (__feholdexcept): Declare. Use libm_hidden_proto. * math/feholdexcpt.c (feholdexcept): Rename to __feholdexcept and define as weak alias of __feholdexcept. Use libm_hidden_weak. * sysdeps/aarch64/fpu/feholdexcpt.c (feholdexcept): Likewise. * sysdeps/alpha/fpu/feholdexcpt.c (feholdexcept): Likewise. * sysdeps/arm/feholdexcpt.c (feholdexcept): Likewise. * sysdeps/hppa/fpu/feholdexcpt.c (feholdexcept): Likewise. * sysdeps/i386/fpu/feholdexcpt.c (feholdexcept): Likewise. * sysdeps/ia64/fpu/feholdexcpt.c (feholdexcept): Likewise. * sysdeps/m68k/fpu/feholdexcpt.c (feholdexcept): Likewise. * sysdeps/mips/fpu/feholdexcpt.c (feholdexcept): Likewise. * sysdeps/powerpc/fpu/feholdexcpt.c (feholdexcept): Likewise. * sysdeps/powerpc/nofpu/feholdexcpt.c (feholdexcept): Likewise. * sysdeps/powerpc/powerpc32/e500/nofpu/feholdexcpt.c (feholdexcept): Likewise. * sysdeps/s390/fpu/feholdexcpt.c (feholdexcept): Likewise. * sysdeps/sh/sh4/fpu/feholdexcpt.c (feholdexcept): Likewise. * sysdeps/sparc/fpu/feholdexcpt.c (feholdexcept): Likewise. * sysdeps/x86_64/fpu/feholdexcpt.c (feholdexcept): Likewise. * sysdeps/generic/math_private.h (default_libc_feholdexcept): Use __feholdexcept instead of feholdexcept. (default_libc_feholdexcept_setround): Likewise. |
