From e1b9c1b01be294cc2865acfe33544d5e5cc50eb4 Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Fri, 27 Jul 2012 00:14:57 -0400 Subject: save AT_HWCAP from auxv for subsequent use in machine-specific code it's expected that this will be needed/useful only in asm, so I've given it its own symbol that can be addressed in pc-relative ways from asm rather than adding a field in the __libc structure which would require hard-coding the offset wherever it's used. --- src/internal/libc.c | 2 ++ src/internal/libc.h | 1 + 2 files changed, 3 insertions(+) (limited to 'src/internal') diff --git a/src/internal/libc.c b/src/internal/libc.c index c1e21ca0..004c1a33 100644 --- a/src/internal/libc.c +++ b/src/internal/libc.c @@ -13,3 +13,5 @@ struct __libc __libc; #ifdef BROKEN_VISIBILITY __asm__(".hidden __libc"); #endif + +size_t __hwcap; diff --git a/src/internal/libc.h b/src/internal/libc.h index 53e4e826..ea863d67 100644 --- a/src/internal/libc.h +++ b/src/internal/libc.h @@ -18,6 +18,7 @@ struct __libc { int ofl_lock[2]; }; +extern size_t __hwcap; #if !defined(__PIC__) || 100*__GNUC__+__GNUC_MINOR__ >= 303 || defined(__PCC__) || defined(__TINYC__) -- cgit v1.2.1
