From 4beed843c11a1f3079c775e501dbe1069e4c7bbe Mon Sep 17 00:00:00 2001 From: Eric Andersen Date: Mon, 21 Aug 2006 23:29:36 +0000 Subject: bits/profil-counter.h and bits/atomicity.h are leftovers from the old gprof based profiling I nuked ages ago since tools like oprofile are non invasive and work so much better. --- libc/sysdeps/linux/powerpc/bits/atomicity.h | 104 ----------------------- libc/sysdeps/linux/powerpc/bits/profil-counter.h | 32 ------- 2 files changed, 136 deletions(-) delete mode 100644 libc/sysdeps/linux/powerpc/bits/atomicity.h delete mode 100644 libc/sysdeps/linux/powerpc/bits/profil-counter.h (limited to 'libc/sysdeps/linux/powerpc') diff --git a/libc/sysdeps/linux/powerpc/bits/atomicity.h b/libc/sysdeps/linux/powerpc/bits/atomicity.h deleted file mode 100644 index 6969749e8..000000000 --- a/libc/sysdeps/linux/powerpc/bits/atomicity.h +++ /dev/null @@ -1,104 +0,0 @@ -/* Low-level functions for atomic operations.
