REGRESSION(317420@main) PAS_ENABLE_MTE can break preprocessed distributed
builds
https://bugs.webkit.org/show_bug.cgi?id=319895
Reviewed by Marcus Plutowski.
Since 317420@main PAS_ENABLE_MTE can appear in contexts where the
preprocessor would output expressions like (0 && 0 && !0), which in turn
could trigger the -Wconstant-logical-operand warning. For example, in
distributed icecc builds where just the final TU is sent.
Currently, this appears in FastMalloc.cpp, with errors like:
bmalloc/Headers/bmalloc/bmalloc_heap_config.h:84:24095: error: use of logical
'&&' with constant operand [-Werror,-Wconstant-logical-operand]
bmalloc/Headers/bmalloc/bmalloc_heap_config.h:84:24095: note: use '&' for a
bitwise operation
bmalloc/Headers/bmalloc/bmalloc_heap_config.h:84:24095: note: remove constant
to silence this warning
* Source/bmalloc/libpas/src/libpas/pas_config.h: Ensure PAS_ENABLE_MTE
resolves to a constant instead of an expression.
