The SGI STL and pre-1998 drafts of the C++ standard had a default
argument for vector::insert(iterator, const bool&) which was
remove by N1051. The default argument is still present in libstdc++ for
some reason. There are no tests verifying it
Hi!
First, you need to adjust after Robin's patch, and retest.

While looking at PR90451 I noticed that this function was failing to find the

We were getting the deprecated warning twice for the same call because we
called mark_used first in finish_qualified_id_expr and then again in
build_over_call. Let's not call it the first time; C++17 clarified that a
function is used only when it is selected from an overload set, which
happens

Don't do int cmoves for IEEE comparisons, PR target/104256.
Protect int cmove from raising an assertion if it is trying to do an int
conditional move where the test involves floating point comparisons that
can't easily be reversed due to NaNs.
The code used to generate the condition, and
This libgo patch, from Svante Signell, adds a hurd build tag for

doesn't test much). Committed to mainline.

This patch exposes two -m* option values which are already
internally available. I think it makes sense to expose them
explicitly to the user (see below), but there are also arguments

The x86 backend piggy-backs on mode-switching for insertion of
vzeroupper. A recent improvement there was implemented in a way
to walk possibly the whole basic-block for all DF reg def definitions
in its mode_needed hook which is called for each instruction in
a basic-block during mode-switching

CD-DCE does not consider CLOBBERs as necessary in the attempt
to not prevent DCE of SSA defs it uses. A side-effect of that
is that it also removes all its control dependences if they are
not made necessary by other means. When we later try to preserve
as many CLOBBERs as possible we have to

Hi!
The following patch uses the functions normal CPP_DEREF parsing uses,
i.e. convert_lvalue_to_rvalue and build_indirect_ref, instead of
blindly calling build_simple_mem_ref, so that if the variable does not
have correct type, we properly diagnose it instead of ICEing on it.
Hi!
The following testcase ICEs on x86_64 when asked to use the pre-GCC 8
ABI where zero sized arguments weren't ignored.
In GCC 7 the emit_push_insn calls in store_one_arg were unconditional,
it is true that they didn't actually push anything because it had zero
size, but because
