Continuing the fixes for C90 libm functions calling C99 fe* functions, this patch fixes the case of fegetround by making it a weak alias of __fegetround and making the affected code call __fegetround. Tested for x86_64 (testsuite, and that disassembly of installed shared libraries is unchanged by the patch). Also tested for ARM (soft-float) that fegetround failures disappear from the linknamespace test failures (feholdexcept, fesetenv, fesetround and feupdateenv remain to be addressed before bug 17748 is fully fixed, although this patch may suffice to fix the failures in some cases, when the libc_fe* functions are implemented but there is no architecture-specific sqrt implementation in use so there were failures from fegetround used by sqrt but no other such failures). [BZ #17748] * include/fenv.h (__fegetround): Declare. Use libm_hidden_proto. * math/fegetround.c (fegetround): Rename to __fegetround and define as weak alias of __fegetround. Use libm_hidden_weak. * sysdeps/aarch64/fpu/fegetround.c (fegetround): Likewise. * sysdeps/alpha/fpu/fegetround.c (fegetround): Likewise. * sysdeps/arm/fegetround.c (fegetround): Likewise. * sysdeps/hppa/fpu/fegetround.c (fegetround): Likewise. * sysdeps/i386/fpu/fegetround.c (fegetround): Likewise. * sysdeps/ia64/fpu/fegetround.c (fegetround): Likewise. * sysdeps/m68k/fpu/fegetround.c (fegetround): Likewise. * sysdeps/mips/fpu/fegetround.c (fegetround): Likewise. * sysdeps/powerpc/fpu/fegetround.c (fegetround): Likewise. Undefine after rather than before function definition; use parentheses around function name in definition. (__fegetround): Also undefine macro after function definition. * sysdeps/powerpc/nofpu/fegetround.c (fegetround): Rename to __fegetround and define as weak alias of __fegetround. Use libm_hidden_weak. Do not undefine as macro. * sysdeps/powerpc/powerpc32/e500/nofpu/fegetround.c (fegetround): Likewise. * sysdeps/s390/fpu/fegetround.c (fegetround): Rename to __fegetround and define as weak alias of __fegetround. Use libm_hidden_weak. * sysdeps/sh/sh4/fpu/fegetround.c (fegetround): Likewise. * sysdeps/sparc/fpu/fegetround.c (fegetround): Likewise. * sysdeps/tile/math_private.h (__fegetround): New inline function. * sysdeps/x86_64/fpu/fegetround.c (fegetround): Rename to __fegetround and define as weak alias of __fegetround. Use libm_hidden_weak. * sysdeps/ieee754/dbl-64/e_sqrt.c (__ieee754_sqrt): Use __fegetround instead of fegetround. |
