This adds an alternative to using #... in dump files, useful where we only want to allow specific extra output. DW_CFA_nop in CIEs and FDEs to pad out to required alignment (larger for 64-bit than 32-bit) is an example where these optional match patterns are useful. binutils/ * testsuite/lib/binutils-common.exp (regexp_diff): Support #?REGEXP. ld/ * testsuite/ld-elf/eh4.d: Match optional padding DW_CFA_nop in FDEs. * testsuite/ld-elf/eh5.d: Likewise, and extra CIEs emitted on embedded targets.
