Use BUILDFLAG(IS_*) instead of defined(OS_*).
This was generated mostly mechnically by performing the following steps:
- sed -i '' -E -e 's/defined\(OS_/BUILDFLAG(IS_/g' \
-e 's%([ !])OS_([A-Z]+)%\1BUILDFLAG(IS_\2)%g' \
$(git grep -l 'OS_'
'**/*.c' '**/*.cc' '**/*.h' '**/*.m' '**/*.mm')
- sed -i '' -e 's/#ifdef BUILDFLAG(/#if BUILDFLAG(/' \
$(git grep -l '#ifdef BUILDFLAG('
'**/*.c' '**/*.cc' '**/*.h' '**/*.m' '**/*.mm')
- gsed -i -z -E -e \
's%(.*)#include "%\1#include "build/buildflag.h"\n#include "%' \
$(git grep -l 'BUILDFLAG(IS_'
'**/*.c' '**/*.cc' '**/*.h' '**/*.m' '**/*.mm')
- Spot checks to move #include "build/buildflag.h" to the correct parts
of files.
- sed -i '' -E -e \
's%^(#include "build/buildflag.h")$%#include "build/build_config.h"\n\1%' \
$(grep -L '^#include "build/build_config.h"$'
$(git grep -l 'BUILDFLAG(IS_'
'**/*.c' '**/*.cc' '**/*.h' '**/*.m' '**/*.mm'))
- Add “clang-format off” around tool usage messages.
- git cl format
- Update mini_chromium to 85ba51f98278 (intermediate step).
TESTING ONLY).
- for f in $(git grep -l '^#include "build/buildflag.h"$'
'**/*.c' '**/*.cc' '**/*.h' '**/*.m' '**/*.mm'); do \
grep -v '^#include "build/buildflag.h"$' "${f}" > /tmp/z; \
cp /tmp/z "${f}"; done
- git cl format
- Update mini_chromium to 735143774c5f (intermediate step).
- Update mini_chromium to f41420eb45fa (as checked in).
- Update mini_chromium to 6e2f204b4ae1 (as checked in).
For ease of review and inspection, each of these steps is uploaded as a
new patch set in a review series.
This includes an update of mini_chromium to 6e2f204b4ae1:
f41420eb45fa Use BUILDFLAG for OS checking
6e2f204b4ae1 Include what you use: string_util.h uses build_config.h
