In Ada, the result of evaluating a function call is a constant object and,
therefore, can be subject to a renaming. This is fully implemented in the
compiler by creating a temporary to capture the return value, either in gigi
for simple cases or in the front-end for more convoluted cases.

I am not sure if suggested fix is the thing we want here. But infact
having here a VAR_DECL can be caused by prior errors introducing them.
So we simply might want to treat VAR_DECL in unify via

Hi!
This patch adds changes similar to those that have been added
for OpenMP 4.1 to the C FE so far. Note, taskloop with C++ class
iterators isn't yet supported and the testsuite coverage is limited too.

Chung-Lin posted this patch last year but it seems never to have been
reviewed:
https://gcc.gnu.org/ml/gcc-patches/2014-06/msg00714.html
I've just re-applied and re-tested it and it still seems to be good.
Can somebody please take a look at it?

When an object is declared with an initializing expression and has its
elaboration delayed, the following code in gnat_to_gnu is invoked:
/* If this object has its elaboration delayed, we must force
evaluation of GNU_EXPR right now and save it for when the object
We don't need the C99-like treatment if we don't expect NaN's.
Tested on x86_64-suse-linux, applied on the mainline.

The change for MIPS looks fine by visual inspection and I've built both
a default pie and default no-pie compiler. The default pie won't build
glibc but I am pretty sure it is not down to this patch. I haven't had
time to look into why it won't build though, something related to

Hi,
I've committed the attached patches to fix PR target/65979
which is a 5/6 regression in behalf of Oleg. The problematic
peephole can clobber a register before its use. See PR65979 for
details. The first patch is for trunk and the second one is
a slightly different version against gcc-5-bran

Committed, thanks.
Hi,
The first patch backports the fix of PR
target/64011(https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64011) to the 4.9
branch from trunk r219717,
and the second patch backports the fix of PR
target/61749(https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61749) to the 4.9
branch from trunk r215046.
Jakub pointed out a formatting issue with one of my recent memory leak
patches. It was a tabs vs spaces issue.
This trivial patch replaces spaces with tabs where appropriate in
tree-ssa-threadedge.c. It has no functional changes.
