Subject: [PATCH] BaseTools/header.makefile: revert gcc-8 "-Wno-xxx" options on OSX
Date: Wed, 7 Mar 2018 10:32:59 +0100 [thread overview]
Message-ID: <20180307093259.7682-1-lersek@redhat.com> (raw)
I recently added the gcc-8 specific "-Wno-stringop-truncation" and
"-Wno-restrict" options to BUILD_CFLAGS, both for "Darwin" (XCODE5 /
clang, OSX) and otherwise (gcc, Linux / Cygwin).
I also regression-tested the change with gcc-4.8 on Linux -- gcc-4.8 does
not know either of the (gcc-8 specific) "-Wno-stringop-truncation" and
"-Wno-restrict" options, yet the build completed fine (by GCC design).
Regarding OSX, my expectation was that
- XCODE5 / clang would either recognize these warnings options (because
clang does recognize most -W options of gcc),
- or, similarly to gcc, clang would simply ignore the "-Wno-xxx" flags
that it didn't recognize.
Neither is the case; the new flags have broken the BaseTools build on OSX.
Revert them (for OSX only).
