From f534255e4d276ee7b20b45637d16a00b122e5df3 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Fri, 17 Apr 2015 10:58:31 -0300 Subject: Consolidate vDSO macros and usage This patch consolidate the Linux vDSO define and usage across all ports that uses it. The common vDSO definitions and calling through {INLINE/INTERNAL}_VSYSCALL macros are moved to a common header sysdep-vdso.h and vDSO name declaration and prototype is defined using a common macro. Also PTR_{MANGLE,DEMANGLE} is added to ports that does not use them for vDSO calls (aarch64, powerpc, s390, and tile) and thus it will reflect in code changes. For ports that already implement pointer mangling/demangling in vDSO system (i386, x32, x86_64) this patch is mainly a code refactor. Checked on x32, x86_64, x32, ppc64le, and aarch64. --- sysdeps/unix/sysv/linux/x86/libc-vdso.h | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'sysdeps/unix/sysv/linux/x86') diff --git a/sysdeps/unix/sysv/linux/x86/libc-vdso.h b/sysdeps/unix/sysv/linux/x86/libc-vdso.h index 79b6411d7e..fea9c2b7a1 100644 --- a/sysdeps/unix/sysv/linux/x86/libc-vdso.h +++ b/sysdeps/unix/sysv/linux/x86/libc-vdso.h @@ -24,7 +24,9 @@ #ifdef SHARED -extern long int (*__vdso_clock_gettime) (clockid_t, struct timespec *) +# include + +extern long int (*VDSO_SYMBOL(clock_gettime)) (clockid_t, struct timespec *) attribute_hidden; #endif -- cgit 1.4.1
