Timur Iskhodzhanov b5f983e4b0 [Sanitizers] Rename Symbolizer::SymbolizeCode to Symbolizer::SymbolizePC
llvm-svn: 197569
2013-12-18 14:17:39 +00:00
Alexey Samsonov 25d010a98d [Sanitizer] Always initialize a Symbolizer (even if 'symbolize' is false).
If 'symbolize' flag is not set, we still want to transform virtual address
to module+offset pair in the call to Symbolizer::SymbolizeCode().
See https://code.google.com/p/address-sanitizer/issues/detail?id=251 for
more details.

Apple's bootstrapped LTO builds have been failing, and these changes (along

these changes or help debug the problem, depending on whether this fixes the
buildbots.

Alexey Samsonov 627e2c0dd7 [Sanitizer] Add Symbolizer::AddHooks() and use it in TSan and MSan.
Summary:
TSan and MSan need to know if interceptor was called by the
user code or by the symbolizer and use pre- and post-symbolization hooks
for that. Make Symbolizer class responsible for calling these hooks instead.
This would ensure the hooks are only called when necessary (during
in-process symbolization, they are not needed for out-of-process) and
save specific sanitizers from tracing all places in the code where symbolization
will be performed.

Peter Collingbourne 791e65dcfb Overhaul the symbolizer interface.
This moves away from creating the symbolizer object and initializing the
external symbolizer as separate steps.  Those steps now always take place
together.

Sanitizers with a legacy requirement to specify their own symbolizer path
should use InitSymbolizer to initialize the symbolizer with the desired
path, and GetSymbolizer to access the symbolizer.  Sanitizers with no
such requirement (e.g. UBSan) can use GetOrInitSymbolizer with no need for
initialization.

The symbolizer interface has been made thread-safe (as far as I can
tell) by protecting its member functions with mutexes.

Finally, the symbolizer interface no longer relies on weak externals, the
introduction of which was probably a mistake on my part.
