From 0d5ba561c1ef3d4abf060bbdba88c29379d4adbe Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Fri, 1 Dec 2017 23:37:46 +0000 Subject: Base powerpc logbl compat symbols on __logb not logb. Some powerpc logb implementations define a compat symbol for logbl based on logb, whereas libm_alias_double defines such a compat symbol based on __logb instead. This difference (logb is weak, __logb isn't) is enough to result in different installed stripped shared libraries. The difference in the installed libraries isn't significant, but first changing the compat_symbol calls helps make it possible to validate a subsequent change to use libm_alias_double by comparison of libraries, so this patch does such a preliminary change. Tested with build-many-glibcs.py for all its hard-float powerpc configurations. * sysdeps/powerpc/power7/fpu/s_logb.c [LONG_DOUBLE_COMPAT (libm, GLIBC_2_0)] (logbl): Define as compat symbol based on __logb, not on logb. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_logb.c [LONG_DOUBLE_COMPAT (libm, GLIBC_2_0)] (logbl): Likewise. * sysdeps/powerpc/powerpc64/fpu/multiarch/s_logb.c [LONG_DOUBLE_COMPAT (libm, GLIBC_2_0)] (logbl): Likewise. --- sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_logb.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'sysdeps/powerpc/powerpc32/power4/fpu') diff --git a/sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_logb.c b/sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_logb.c index fddd1ecbec..f178967f0e 100644 --- a/sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_logb.c +++ b/sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_logb.c @@ -37,5 +37,5 @@ weak_alias (__logb, logbl) #endif #if LONG_DOUBLE_COMPAT (libm, GLIBC_2_0) -compat_symbol (libm, logb, logbl, GLIBC_2_0); +compat_symbol (libm, __logb, logbl, GLIBC_2_0); #endif -- cgit 1.4.1
