static void foo (void) __attribute__((used));
static void foo (void)
void bar (void)
void (*p) () = foo;
has it for ppc64 (for ia64 not right now, as DECL_MODE != TYPE_MODE in
expand_debug_expr prevents it). ppc64 produces at -O2 -g -dA -m64:
.byte 0x4 # uleb128 0x4; (DIE (0x9b) DW_TAG_variable)
.ascii "p\0" # DW_AT_name
.byte 0x1 # DW_AT_decl_file (tt.c)
.byte 0x8 # DW_AT_decl_line
.4byte 0xb7 # DW_AT_type
.byte 0xa # DW_AT_location
.byte 0x3 # DW_OP_addr
.byte 0x9f # DW_OP_stack_value
which is I think correct, as unlike ia64 on ppc64 foo here is the function
descriptor symbol in .opd.
