Concluding the fixes for C90 libm functions calling C99 fe* functions, this patch fixes the case of feupdateenv by making it a weak alias for __feupdateenv and making the affected code call __feupdateenv. Tested for x86_64 (testsuite, and that installed stripped shared libraries are unchanged by the patch). Also tested for ARM (soft-float) that the math.h linknamespace tests now pass. [BZ #17748] * include/fenv.h (__feupdateenv): Use libm_hidden_proto. * math/feupdateenv.c (__feupdateenv): Use libm_hidden_def. * sysdeps/aarch64/fpu/feupdateenv.c (feupdateenv): Rename to __feupdateenv and define as weak alias of __feupdateenv. Use libm_hidden_weak. * sysdeps/alpha/fpu/feupdateenv.c (__feupdateenv): Use libm_hidden_def. * sysdeps/arm/feupdateenv.c (feupdateenv): Rename to __feupdateenv and define as weak alias of __feupdateenv. Use libm_hidden_weak. * sysdeps/hppa/fpu/feupdateenv.c (feupdateenv): Likewise. * sysdeps/i386/fpu/feupdateenv.c (__feupdateenv): Use libm_hidden_def. * sysdeps/ia64/fpu/feupdateenv.c (feupdateenv): Rename to __feupdateenv and define as weak alias of __feupdateenv. Use libm_hidden_weak. * sysdeps/m68k/fpu/feupdateenv.c (__feupdateenv): Use libm_hidden_def. * sysdeps/mips/fpu/feupdateenv.c (feupdateenv): Rename to __feupdateenv and define as weak alias of __feupdateenv. Use libm_hidden_weak. * sysdeps/powerpc/fpu/feupdateenv.c (__feupdateenv): Use libm_hidden_def. * sysdeps/powerpc/nofpu/feupdateenv.c (__feupdateenv): Likewise. * sysdeps/powerpc/powerpc32/e500/nofpu/feupdateenv.c (__feupdateenv): Likewise. * sysdeps/s390/fpu/feupdateenv.c (feupdateenv): Rename to __feupdateenv and define as weak alias of __feupdateenv. Use libm_hidden_weak. * sysdeps/sh/sh4/fpu/feupdateenv.c (feupdateenv): Likewise. * sysdeps/sparc/fpu/feupdateenv.c (__feupdateenv): Use libm_hidden_def. * sysdeps/tile/math_private.h (__feupdateenv): New inline function. * sysdeps/x86_64/fpu/feupdateenv.c (__feupdateenv): Use libm_hidden_def. * sysdeps/generic/math_private.h (default_libc_feupdateenv): Call __feupdateenv instead of feupdateenv. (default_libc_feupdateenv_test): Likewise. (libc_feresetround_ctx): Likewise.
