[LLVMdev] Trouble with tweaking test-release.sh script

[陳韋任]

Hi Bill,

  The preliminary result of regression test on ARM shows quit a lot failures,
which makes me nervous. After discussion on IRC, echristo and chandlerc sugguested
the following possibilities,

  1) some flag weirdness
  2) miscompile via cross toolchain
  3) architecture-specific fundamental bug

chandlerc told me compile LLVM/Clang without "-fno-strict-aliasing" first, see
if those failures gone. If not, turn off all optimizations when building
LLVM/Clang. But I have trouble with tweaking test-release.sh so that it can
compile with "-fno-strict-aliasing" option. You can see the script I modified
at [2]. Although I set CFLAGS and CXXFLAGS to "-fno-strict-aliasing", I see
no "-fno-strict-aliasing" in llvm.make-Phase1-Release.log, seems CFLAGS and
CXXFLAGS don't work. Do you know the correct way to enable/disable compiler
options?

  Thanks! :)

Regards,
chenwj
