Hi,
gfortran has a few long-standing bugs wrt module handling. The more
fundamental, and also more difficult to fix, issue is that we re-read
and re-parse module files every time a USE statement is encountered,
instead of once per translation unit. See PR 25708. Another issue, PR
40958, is that mo

My main comment is that we shouldn't need to track separate liveness
sets for each loop here, since we're only looking at one basic block.
I.e., rather than operate on the per-loop LO

The problem is that not always the ts.u.derived->backend_decl was copied
as well. I copied what was done a bit later in the file and extended it
to also include BT_CLASS.
The trans-type.c change is not needed, but I thought

Hello!
Attached patch introduces sync_int128_runtime and
sync_long_long_runtime runtime check to prevent running atomic runtime
tests on targets that don't support them. I also merged runtime check
for arm*-*-linux-gnueabi with corresponding arm*-*-* compile-time
check. This change has a nice side
Hi!
The following testcase ICEs during flow verification, because there is
an unconditional branch with EDGE_PRESERVE set on the edge and because of
that bit rtl_verify_flow_info_1 wouldn't count it as n_branch.

trunk?

Hello!
Attached patch enables sync_long_long tests on 32bit x86 and alpha.
Enabling the tests for alpha is obvious (it is 64bit-by-default
target, after all), but 32bit x86 needs at least -march=pentium passed
via dg-options. My previous patch checks bit_CMPXCHG8B cpuid bit

Adding -msse to failing test works OK.

Hi!
While looking at this PR, I was first surprised that on i?86
we got pseudo = argp + 4 and mem_overlap* was called with
that pseudo + 4 etc. I don't see why we should force the address
into register for EXPAND_SUM modifier, with this mem_overlap* sees
argp + 8 etc. directly (on i?86, of course

On load-store architectures, the function address is generally loaded into
a register before any outgoing arguments are stored in the stack frame
(if any). Thus, generally allowing memory loads before any arguments of
the sibcall have been stored in the stack frame is effective to make the
sibcal
