From 12e9b4faf68a1a02ebf5ad69c03ac10f170f14cb Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Thu, 11 Oct 2012 22:47:07 -0400 Subject: i386 vsyscall support (vdso-provided sysenter/syscall instruction based) this doubles the performance of the fastest syscalls on the atom I tested it on; improvement is reportedly much more dramatic on worst-case cpus. cannot be used for cancellable syscalls. --- src/internal/libc.c | 1 + 1 file changed, 1 insertion(+) (limited to 'src/internal/libc.c') diff --git a/src/internal/libc.c b/src/internal/libc.c index 004c1a33..d22d2747 100644 --- a/src/internal/libc.c +++ b/src/internal/libc.c @@ -15,3 +15,4 @@ __asm__(".hidden __libc"); #endif size_t __hwcap; +size_t __sysinfo; -- cgit 1.4.1
