We still have the problem that function locals in dwarf2out are seen in
decls_for_scope by iterating through BLOCK_VARS, and temporaries do not
live in BLOCK_VARS.
How did they get picked up and annotated in your approach?
The size type ones are in BLOCJ_VARS IIRC (or I have to check the last posted
patch for other related hunks).
Hmmm, it doesn't seem so in my testcase:
$ cat a.c
unsigned int i=555;
int main()
{
unsigned int array[i];
__asm__ __volatile__ ("" : : "m" (array));
}
(gdb) print stmt
$108 = <block 0x7ffff02b0420>
(gdb) call debug_generic_stmt(stmt)
BLOCK #0
SUPERCONTEXT: main
VARS: array
The temporary has DECL_IGNORED_P appropriately.
It does show up in DECL_STRUCT_FUNCTION()->local_decls, but so do a few
other temporaries and SSA variables which we're not interested in.
