Subject: llvm-readobj: zero out timestamp in COFF auto-generated test files.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=f34a60c9208d3496c0471ea6effdecd54b2bf932;p=llvm

llvm-readobj: zero out timestamp in COFF auto-generated test files.

The timestamp meant these files changed with each invocation of
relocs.py, confusing matters when we add relocations and need to
update the tests.
