Richard,
For the example from the PR, -ftree-tail-merge discovers that blocks 6 and 7 are
equal, removes block 7 and redirects the outgoing edge of it's predecessor block
11 to block 6.
Block 6 contains a phi, which after redirecting the edge from block 11 looks
like this:
...
.MEM_54 = PHI <.MEM

Hi,
this patch makes cgraph code to also handle wekrefs as long as their
destination declaration is known. The cases where it is not still needs
updating at lto-symtab I plan to do incrementally.
The basic idea is to handle weakrefs as external declaration (so they

Hi,
this seems fine for mainline. I am not 100% sure it is best choice of metric
(i.e. mostly one is interested if hot blocks identified by static profile cover
hot blocks of real profile), but we could get some experience with it.
Thanks

This fixes PR50780 by validating a condition is gimple before
substituting it into a COND_EXPR during forwprop. When looking

As was pointed out, __get_builtin_sync_mem was renamed to
__get_builtin_atomic which isn't really right, so this patch renames it

It also includes some formatting fixes which resulted from __sync_mem

So while tracking down a hairy address reload for an output reload bug,
copyprop_hardreg_forward_1 was faulting because it was trying to extract move
patterns that didn't work out, and when it came back to the code, it then tries
to access recog_data, but the problem is, the exploration of other
Hi,
It appears that m68k floating-point comparisons may have been
subtly broken since 2007 when the following patch was applied:
http://gcc.gnu.org/ml/gcc-patches/2007-09/msg01570.html
The bug shows with our internal 4.6-based branch, but appears to be
latent on mainline (generated code is per
Hi,
in these two twin PRs filed by Ian and Gerald, it is pointed out that
cases like:
struct C {
int f() { return 1; }
};
int f(C&c) {
return ( 1 == c.f );
}
where the user actually forgot the open-closed round braces are much
more likely than cases where an ampersand

When bot_manip regenerates TARGET_EXPR/AGGR_INIT_EXPR, it needs to
preserve the AGGR_INIT_ZERO_FIRST flag.

Hi,
this tries to implement what Jason suggested in the audit trail: do not
refer to an argument and use instead 'cannot convert...", like, eg, in
cvt.c.
Tested x86_64-linux.

The testcase gcc.dg/tree-prof/val-prof-7.c includes to get
a declaration of bzero. This causes it to fail on targets where bzero
(a legacy function removed in the latest version of POSIX) is not
declared in that header; declaring it explicitly in the testcase is
more reliable. This patch changes
