Since a recent change to the tree optimizers

this.
Tested briefly with 'make all' and with
make -k check-gcc
X32 doesn't support indirect branch via 32-bit memory slot since
indirect branch will load 64-bit address from 64-bit memory slot.
Since x32 GOT slot is 64-bit, we should allow indirect branch via GOT
slot for x32.
I am testing it on x32. OK for master if there is no regression?
Thanks.

Ouch. The peephole in problem was added at gcc-5 not at 4.9. The above

The only serious problem with the patch is that it changes Makefile.in,
but not the corresponding part of Makefile.tpl from which it is

Now, if you'd also update the comments just before it, that still

For the interpretation of (intrinsic) assignment, you have to look at

The execution of the assignment shall have the same effect as if

I think you want DECL_IS_BUILTIN. OK with that change.
Right. With DECL_IS_BUILTIN we print

When GCC defaults to C++14, it gives -Wsized-deallocation warnings for
the non-sized operator deletes. We dealt with this for the sized ones
by passing -Wno-sized-deallocation on the command line, but using
#pragma GCC diagnostic seems cleaner to me.
Applying to trunk.

When combine needs to split a complex insn, it will canonicalize a

once more...).

Hi,
I have not managed to ping this, get it approved and commit it in time
for gcc 5 but it is a useful cleanup that clarifies a number of things
and something I'd like to base further cleanups on. It still applies
cleanly and I have re-tested and re-bootstrapped the patch on
x86_64-linux
The AIX port of GCC is one of the few ports that does not define
NO_IMPLICIT_EXTERN_C. A user reported a problem that we tracked to an
AIX header that explicitly used C++ features (bracketed by #ifdef
__cplusplus).
AIX headers have included some C++ features, mostly protected by
#if defined

Here is the complete patch. Tested on Linux/x86-64. It is also

As always, please keep generated files like configure and config.in out
of the submission: it simplifies review.

Ouch. The peephole in problem was added at gcc-5 not at 4.9. The above
patch should fix the original conftest.c issue, but debien 4.9-16 problem
would be an another issue.
