* dw2gencfi.c (TC_DWARF2_EMIT_OFFSET): Provide default.
(output_fde): Use it. Make sure to fully init exp before using it.
testsuite/
* gas/cfi/cfi-common-1.d: Use objdump instead of readelf to dump.
* gas/cfi/cfi-common-2.d, gas/cfi/cfi-common-3.d,
gas/cfi/cfi-common-4.d, gas/cfi/cfi-common-6.d,
gas/cfi/cfi-common-7.d, gas/cfi/cfi-x86_64.d: Likewise.
* gas/cfi/cfi-x86_64.s: Remove .type directives.
* gas/cfi/cfi.exp: Run for pecoff objects too.
* gas/cfi/reloc-pe-i386.d, gas/cfi/reloc-pe-i386.s: New test.
