From 01238691bb03f0110455b663439eecf9a58c8f83 Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Wed, 7 Jan 2015 00:41:23 +0000 Subject: Fix libm fesetround namespace (bug 17748). Continuing the fixes for C90 libm functions calling C99 fe* functions, this patch fixes the case of fesetround by making it a weak alias of __fesetround and making the affected code call __fesetround. An existing __fesetround function in fenv_libc.h for powerpc is renamed to __fesetround_inline. Tested for x86_64 (testsuite, and that disassembly of installed shared libraries is unchanged by the patch). Also tested for ARM (soft-float) that fesetround failures disappear from the linknamespace test results (feupdateenv remains to be addressed to complete fixing bug 17748). [BZ #17748] * include/fenv.h (__fesetround): Declare. Use libm_hidden_proto. * math/fesetround.c (fesetround): Rename to __fesetround and define as weak alias of __fesetround.
