From 36be5284c2a79406778ac489928c6deb05857329 Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Sat, 13 Oct 2012 23:53:18 -0400 Subject: [PATCH 1/1] workaround broken hidden-visibility handling in pcc with this change, pcc-built musl libc.so seems to work correctly. the problem is that pcc generates GOT lookups for external-linkage symbols even if they are hidden, rather than using GOT-relative addressing. the entire reason we're using hidden visibility on the __libc object is to make it accessible prior to relocations -- not to mention inexpensive to access. unfortunately, the workaround makes it even more expensive on pcc. when the pcc issue is fixed, an appropriate version test should be added so new pcc can use the much more efficient variant. --- src/internal/libc.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/internal/libc.h b/src/internal/libc.h index f88d846d..703d9853 100644 --- a/src/internal/libc.h +++ b/src/internal/libc.h @@ -21,7 +21,7 @@ struct __libc { extern size_t __hwcap; -#if !defined(__PIC__) || 100*__GNUC__+__GNUC_MINOR__ >= 303 || defined(__PCC__) || defined(__TINYC__) +#if !defined(__PIC__) || (100*__GNUC__+__GNUC_MINOR__ >= 303 && !defined(__PCC__)) #ifdef __PIC__ #if __GNUC__ < 4 -- 2.20.1
