From: Carlos Eduardo Seo Date: Wed, 9 Dec 2015 20:48:04 +0000 (-0200) Subject: powerpc: Export __parse_hwcap_and_convert_at_platform to libc.a. X-Git-Tag: glibc-2.23~102 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=c676e659395f145e45b08fe3bba90c29ab44e8b8;p=thirdparty%2Fglibc.git powerpc: Export __parse_hwcap_and_convert_at_platform to libc.a. Commit 67385a01d229751569b6aac067ffdcd813a15d7a added a new feature for powerpc, where we store HWCAP/Platform bits in the TCB. In the dynamic linking case, we use the versioned symbol '__parse_hwcap_and_convert_at_platform' to verify if this feature is available. However, the same symbol was not exported to libc.a, making it not possible for GCC to check for it prior to link time. --- diff --git a/ChangeLog b/ChangeLog index 83143de1008..a32717ea056 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,8 @@ +2015-12-22 Carlos Eduardo Seo + + * sysdeps/powerpc/hwcapinfo.c: Export symbol + __parse_hwcap_and_convert_at_platform to libc.a. + 2015-12-22 Carlos Eduardo Seo * sysdeps/powerpc/dl-procinfo.c (_dl_powerpc_platforms): Added diff --git a/sysdeps/powerpc/hwcapinfo.c b/sysdeps/powerpc/hwcapinfo.c index a115ffccd9e..b885f1cff6e 100644 --- a/sysdeps/powerpc/hwcapinfo.c +++ b/sysdeps/powerpc/hwcapinfo.c @@ -74,3 +74,11 @@ __tcb_parse_hwcap_and_convert_at_platform (void) versioned_symbol (ld, __tcb_parse_hwcap_and_convert_at_platform, \ __parse_hwcap_and_convert_at_platform, GLIBC_2_23); #endif + +/* Export __parse_hwcap_and_convert_at_platform in libc.a.
