Convert inliner to new param infrastructure
/bin/sh: :q: command not found
This patch adds opt_for_fn for all cross module params used by inliner
so they can be modified at function granuality. With inlining almost always
there are three functions to consider (callee and caller of the inlined edge
and the outer function caller is inlined to).
I always use the outer function params since that is how local parameters
behave. I hope it is kind of what is also expected in most case: it is better
to inline agressively into -O3 compiled code rather than inline agressively -O3
functions into their callers.
New params infrastructure is nice. One drawback is that is very hard to
search for individual param uses since they all occupy global namespace.
With C++ world we had chance to do something like params.param_flag_name
or params::param_flag_name instead...

The tests amended here now have different code-gen with default

ABI for common accesses. The revised code-gen does not match the
expected scan-asms because Darwin defaults to fPIC. For these tests,

Make more bad uses of fallthrough attribute into pedwarns.
Various bad uses of the [[fallthrough]] attribute are constraint

This patch duly turns the relevant warnings into pedwarns. The
relevant code is not specific to C, and does not know which form the
attribute was given in ([[fallthrough]] or [[gnu::fallthrough]] or

also erroneous for C++ and it seems reasonable to give a pedwarn here
even when a form other than [[fallthrough]] is being used.
The precise meaning of the standard wording about "The next statement
that would be executed" seems a but unclear in some corner cases; the
tests added keep to cases where it is clear whether or not the next
statement executed is of the required form.

jit: fix ICE with GCC_JIT_BOOL_OPTION_SELFCHECK_GC since r278084 (PR jit/92483)
Since r278084 (part of the params refactoring), most of libgccjit's
test suite has been ICEing.
The root cause is that jit-playback.c injects params to its fake_args
here:
/* Aggressively garbage-collect, to shake out bugs: */
if (get_bool_option (GCC_JIT_BOOL_OPTION_SELFCHECK_GC))
{
ADD_ARG ("--param");
ADD_ARG ("ggc-min-expand=0");
ADD_ARG ("--param");
ADD_ARG ("ggc-min-heapsize=0");
}
(building a vec of char * where the char * are allocated using xstrdup)
and r278084 added this logic to decode_cmdline_options_to_array:
964 /* Interpret "--param" "key=name" as "--param=key=name". */
965 const char *needle = "--param";
966 if (i + 1 < argc && strcmp (opt, needle) == 0)
967 {
968 const char *replacement
969 = opts_concat (needle, "=", argv[i + 1], NULL);
970 argv[++i] = replacement;
971 }
Note that at line 970 it manipulates the argv in-place, inserting a
new option allocated with opts_concat, which uses opts_obstack
(itself initialized from toplev::main).
jit-playback.c cleans up its fake arguments using "free", at which
point we have a free of the middle of an obstack and an ICE.
This patch fixes the issue by using the new syntax for the params.
Fixes all 60 FAILs in jit.sum, restoring the number of PASS results
from 2033 to 10469.

libgomp/test: Add flags to find libatomic in build-tree testing
Add flags to find libatomic in build-tree testing, fixing a catastrophic
libgomp testsuite failure with `riscv*-*-linux*' targets, which imply
`-latomic' with the `-pthread' GCC option, implied in turn by the
`-fopenacc' and `-fopenmp' options, removing failures like:
.../bin/riscv64-linux-gnu-ld: cannot find -latomic
collect2: error: ld returned 1 exit status
compiler exited with status 1
FAIL: libgomp.c/../libgomp.c-c++-common/atomic-18.c (test for excess errors)
Excess errors:
.../bin/riscv64-linux-gnu-ld: cannot find -latomic
UNRESOLVED: libgomp.c/../libgomp.c-c++-common/atomic-18.c compilation failed to produce executable
and bringing overall test results for the `riscv64-linux-gnu' target
(here with the `x86_64-linux-gnu' host and RISC-V QEMU in the Linux user
emulation mode as the target board) from:
=== libgomp Summary ===
# of expected passes 90
# of unexpected failures 3267
# of expected failures 2
# of unresolved testcases 3247
# of unsupported tests 548
to:
