Subject: Revert r358405: "[llvm-objdump] Align instructions to a tab stop in disassembly output"
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=a164cf508d1335830c9360bfb2c79c4a7676b102;p=llvm

Revert r358405: "[llvm-objdump] Align instructions to a tab stop in disassembly output"

The test fails on darwin due to a sed error:

sed: 1: "y/\t/ /": transform strings are not the same length
