Hi.
Sending GCC 6 branch backports.
Patches can bootstrap on ppc64le-redhat-linux and survives regression tests.
I'm going to install the patches.

Hi,
Patch has been updated and tested. Now I don't see any new regressions.
Changelog stays the same.
Is it ok for trunk?
Thanks,

The following patch^Whack splits $subject files into three, one
for the predicates (due to an implementation detail) and two for
the rest - for now into similar LOC size files.
I'd like to get help on the makefile changes to make them less
verbose, somehow globbing the -[12p] parts.

It's always been ill-formed to say "return;" in a non-void function,
the change in GCC 8 is when control flows of the end of a function.
This corrects the release notes.

OK for mainline and gcc-8 backport after a couple of days, the latter
also needs approval from RM.

The following patch improves bootstrap times in general, without
resorting to file splitting. The observation that stage2 build
of gimple-match.c improves by 50% when using -fno-checking
suggests that we avoid doing redundant checking when bootstrapping
and simply disable that when using the slow

Thank you for the prompt review and careful feedback. I didn't notice
your message until this morning. At this point, I'll wait a few days before
committing these changes as I understand we are still in the "RC phase of GCC
8".

OK for trunk and gcc-8-branch?
commit 20357a8ded851a3376b7e8978c77e7c56b1a273e

Document that -Wreturn-type is enabled by default for C++
In function minmax_replacement in tree-ssa-phiopt.c, MIN_EXPR/MAX_EXPR
are substituted for when the following condition is false - (HONOR_NANS
(type) || HONOR_SIGNED_ZEROS (type)). So for FP mode, this is false when
_both_ of the following conditions are fulfilled : 1. flag_signed_zeros
is zero
Hi all,
I'm going to commit this patch to all active branches as soon as the
branch status permits.
Built and tested on native armv5 FreeBSD12.

The patches enabling ASAN for MIPS (32-bit) have now been
committed, on trunk for gcc-9. I didn't persist pinging release
maintainers for gcc-8, but I'd certainly like to backport them,
if so allowed.

Jakub and Richi,
GCC 8.1 is experiencing the same bootstrap failure with GCC 8.1 RC1 as
we saw previously.
Bootstrap comparison failure!

And the same reason: unique, static symbol that includes a random timestamp.

in an unaligned pointer value. This patch adds -Waddress-of-packed-member

well as unaligned pointer:
