Adjust use of macros from atomicity.h to new names and semantics. * gmon_mcount.c: Likewise. * malloc/set-freeres.c: Likewise. * nscd/cache.c: Likewise. * stdlib/cxa_finalize.c: Likewise. * sysdeps/unix/sysv/linux/getsysstats.c: Likewise. * sysdeps/mips/ieee754.h: New file, suitable to replace both * stdlib/strtod.c (INTERNAL): While eating trailing zeros handle --- sysdeps/ia64/atomicity.h | 48 ----------------------- sysdeps/ia64/bits/atomic.h | 97 ++++++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 97 insertions(+), 48 deletions(-) delete mode 100644 sysdeps/ia64/atomicity.h create mode 100644 sysdeps/ia64/bits/atomic.h (limited to 'sysdeps/ia64') diff --git a/sysdeps/ia64/atomicity.h b/sysdeps/ia64/atomicity.h deleted file mode 100644 index 615befd580..0000000000 --- a/sysdeps/ia64/atomicity.h +++ /dev/null @@ -1,48 +0,0 @@ -/* Low-level functions for atomic operations.
