Fix wrong code with pure functions
I introduced bug into find_func_aliases_for_call in handling pure functions.
Instead of reading global memory pure functions are believed to write global

Hi Rasmus,
We have had to use for stdbool a similar trick as we had
for stdint (need to preinclude yyvals.h), which we will need to

Hi,
using -fno-semantic-interposition has been reported by various people
to bring about considerable speed up at the cost of strict compliance

Hi!
My recent libgomp change apparently broke libgomp build for gcn offloading.
The problem is that gcn, unlike nvptx, doesn't override teams.c source file
and the patch I've committed assumed all the non-LIBGOMP_USE_PTHREADS targets
do not use it. My understanding is that gcn included omp_get_nu
Hello,
This patch teaches the DWARF support in gcc about RA_AUTH_CODE pseudo
hard-register and also
.save {ra_auth_code} and .cfi_offset ra_auth_code dwarf directives for
the PAC feature
in Armv8.1-M architecture.
RA_AUTH_CODE register number is 107 and it's dwarf register number is 143.

This patch converts one more open coded construction of a

No, the patch is simple so I didn't write any message (except commit title).

The PR shows a missed control-dependent DCE caused by CFG cleanup

Hi!
Here is an completely untested attempt at implementing what I was talking
about, that for num_teams_upper 0 or whenever num_teams_lower <= num_blocks,
the current implementation is fine but if the user explicitly asks for more
teams than we can provide in hardware, we need to stop assuming tha

Hi,
this patch fixes bug I introduced while breaking up the bigger change.
We currently can not use pure/const to discover looping pures&const
since lack of global memory writes/stores does not imply we can CSE on
the function. THis is witnessed by testsuite doing volatile asm
or also can happen i

This replaces the printf used by failed debug assertions with fprintf,
so we can write to stderr.
To avoid including the assert function is moved into the
library. To avoid programs using a vague linkage definition of the old
inline function, the function is renamed. Code compiled with old
