Subject: Update llvm-obdump(1) to print FAT_MAGIC_64 for Darwin’s 64-bit universal files
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=6a96160ebaae508e540cc68ca8ee9c2e9bd685fb;p=llvm

Update llvm-obdump(1) to print FAT_MAGIC_64 for Darwin’s 64-bit universal files
with the -macho and -universal-headers flags.

Just a follow on to r273207, I missed updating the printing of the fat magic
number when the universal file is a 64-bit universal file.
