Log:
Fix miscompile and rejects-valids when disambiguating after an ambiguous
C-style-cast to function/array type or parenthesized function-style cast/array
indexing.
Hi Richard,
After bisecting, I found that your commit is the responsible for this
test-suite failure on AArch64:
1.
/external/buildbot/clang-native-arm-lnt/test/test-suite/MultiSource/Benchmarks/MallocBench/gs/zpaint.c:181:45:
current parser token ';'
2.
/external/buildbot/clang-native-arm-lnt/test/test-suite/MultiSource/Benchmarks/MallocBench/gs/zpaint.c:165:1:
parsing function body 'image_continue'
3.
/external/buildbot/clang-native-arm-lnt/test/test-suite/MultiSource/Benchmarks/MallocBench/gs/zpaint.c:165:1:
in compound statement ('{}')
4.
/external/buildbot/clang-native-arm-lnt/test/test-suite/MultiSource/Benchmarks/MallocBench/gs/zpaint.c:181:5:

Can you have a look, please?

This causes a similar failure on powerpc64 (both big and little endian).
Note that this was found during the running of the lnt tests.
