/* Print debug labels as "foo = ." rather than "foo:" because they should
represent a byte pointer rather than an ISA-encoded address. This is
particularly important for code like:
$LFBxxx = .
.cfi_startproc
...
.section .gcc_except_table,...
...
.uleb128 foo-$LFBxxx
The .uleb128 requies $LFBxxx to match the FDE start address, which is
likewise a byte pointer rather than an ISA-encoded address.
At the time of writing, this hook is not used for the function end
label:
$LFExxx:
.end foo
But this doesn't matter, because GAS doesn't treat a pre-.end label
as a MIPS16 one anyway. */
