However, that brings up an couple interesting questions.
Let's say we find a NULL pointer which reaches a return statement in a
function which is marked as returns_nonnull. In that case there is no
dereference. Presumably for that kind of scenario we'll just keep the
builtin trap.

Building latest gcc+go on CentOS 5.10 breaks with following build failure:
../../../gcc-svn/trunk/libgo/go/net/fd_unix.go:414:72: error:
reference to undefined identifier ‘syscall.F_DUPFD_CLOEXEC’
r0, _, e1 := syscall.Syscall(syscall.SYS_FCNTL, uintptr(fd),
syscall.F_DUPFD_CLOEXEC, 0)
Here is the patch that includes profile-tool.
Profile-tool now has two functions: merge and rewrite. I'll add diff later.
Compiler is tested with spec2006 and profiledbootstrap.
profile-tool is tested with spec2006 profiles.
Hi,
it would be nice if you could elaborate bit more on the tool

Hi!
Dunno how I've managed to break the branch on Friday, anyway, here is an
obvious fix, committed to the branch.

Due to the different interfaces of int_size_in_bytes and
simple_type_size_in_bits (and 'size' in add_byte_size_attribute being
unsigned and not [unsigned] HWI) it would be cleaner to
add an early return after the call to int_size_in_bytes if its
return value is -1 (and make sure the return
Hi Yufeng,
The idea is a good one but I don't like your implementation of adding an
extra expression parameter to look at on the find_basis_for_candidate
lookup. This goes against the design of the pass and may not be
sufficiently general (might there be situations where a third possible
