New issue 3170 by [email protected]: A64: Enable AssertStackConsistency
in PrepareForPush.
http://code.google.com/p/v8/issues/detail?id=3170
AssertStackConsistency was added to PrepareForPush in r19474, but disabled
in r19491 because it generates too much code and causes some tests to fail
(intermittently). We should find a way to enable this assertion, either by
optimizing the size of some generated code, or by increasing the size of
the relevant buffers.
This assertion is known to trigger the following failures on a debug build
with snapshot=off:
# Fatal error in ../src/a64/assembler-a64.cc, line 2342
# external code buffer is too small
- cctest/test-api/MultipleIsolatesOnIndividualThreads
- cctest/test-lockers/MultithreadedParallelIsolates
- cctest/test-lockers/LockAndUnlockDifferentIsolates
- cctest/test-lockers/ExtensionsRegistration
# Fatal error in ../src/spaces.cc, line 2378
# CHECK(size_in_bytes <= kMaxBlockSize) failed
- cctest/test-serialize/DeserializeFromSecondSerialization
- cctest/test-serialize/DeserializeFromSecondSerializationAndRunScript2
# Fatal error in ../test/cctest/test-spaces.cc, line 412
# CHECK_EQ(1, isolate->heap()->paged_space(i)->CountTotalPages()) failed
# Expected: 1
# Found: 2
- cctest/test-spaces/SizeOfFirstPageIsLargeEnough
