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.

/* Internally, we suppress any use of exception or rounding other
|
|
than what is supported by the hardware. This does mean that some
|
|
code will silently fail to report exceptions, set rounding mode
|
|
as expected, etc., but it allows math code to compile that otherwise
|
|
wouldn't (such as math/s_fma.c) and so is valuable.
|
|
|
|
We intentionally ignore the "exception" arguments of functions that
|
|
take an exception, since we can't even evaluate the argument
|
|
without causing a build failure. The extra level of statement
|
|
expression wrapping avoids "statement with no effect" warnings.
|
|
Since the callers don't check for errors anyway, we just claim
|
|
success in every case.
|
|
|
|
The overrides for libc_ functions must happen before we include
|
|
the generic math_private.h, and the overrides for regular
|
|
<fenv.h> functions must happen afterwards, to avoid clashing with
|
|
the declarations of those functions. */
