In addition looks like we need to handle
(minus (const_int) (sym_ref)) because with the reduced testcase with -g and
removing the -fdata-sections I get an error with
const ( minus (323) (sym_ref)) and gas won't grok that because there is no
relocation that will deal with this.
(note 220 219 221 5 (var_location r2 (plus:SI (plus:SI (reg:SI 3 r3 [orig:192
ivtmp.37 ] [192])
(symbol_ref:SI ("*.LANCHOR0") [flags 0x182]))
(const:SI (minus:SI (const_int 323 [0x143])
(symbol_ref:SI ("*.LANCHOR0") [flags 0x182])))))
NOTE_INSN_VAR_LOCATION)
Uggh this is proving to be more ugly.
