Hi All,
This test is somewhat broken, on systems with the profiling extension it fails
because the +profile is required.
The functionality tested here is already tested in nativecpu tests, so deleting

As the testcase shows, this pattern had an incorrect constraint leading

Perhaps I'm missing something (I'm not too familiar with SVE semantics), but

The -funwind-tables and -fasynchronous-unwind-tables options are relevant
for the output pass, so they need to be passed through by the LTO wrapper.
Otherwise, dwarf2out_assembly_start may output a ".cfi_sections

The -mstack-size option has been marked obsolete in favour of setting an

Dear all,
as the PR shows, it is likely not a good idea to try to make an
ASSOCIATE variable static when -fno-automatic is specified, so
rather keep it on the stack.
