Evgeniy Stepanov f294d5b829 [sanitizer] Flag parser rewrite.
The new parser is a lot stricter about syntax, reports unrecognized
flags, and will make it easier to implemented some of the planned features.

Alexey Samsonov 03499e920b [Sanitizer] Change the runtime flag representation.
This mirrors r225239 to all the rest sanitizers:
ASan, DFSan, LSan, MSan, TSan, UBSan.

Now the runtime flag type, name, default value and
description is located in the single place in the
.inc file.

Alexey Samsonov 2e39027931 [LSan] Parse common flags from LSAN_OPTIONS even if LSan is combined with
another sanitizer.

A user may run both LSan and LSan+ASan. It is weird to pass path to leak
suppression file (or other common sanitizer flags, like "verbosity") in
"LSAN_OPTIONS" in the first case and in "ASAN_OPTIONS" in the second case.

Alexey Samsonov 77f646c623 [Sanitizer] Make "suppressions" and "print_suppressions" common runtime flags.
No functionality change.

Sergey Matveev 27aea0b0b7 [lsan] Refactor the LeakReport class.
Those methods were too damn bloated.

Sergey Matveev 625875d256 [lsan] Make the report_objects flag more useful.
Print the list of leaked objects after each leak report. Previously we
printed only a joint list of all leaked objects. As a bonus, suppressed objects
are no longer reported.

Sergey Matveev 149b794ec6 [lsan] Remove the LSan-specific verbosity flag.
It conflicted with the verbosity flag we had in common flags. We don't need an
LSan-specific flag anyway.

Also, shift some logging levels and remove some unnecessary code.

Sergey Matveev b5769dbb86 [lsan] Introduce print_suppressions flag.
Introduce a flag to either always or never print matched suppressions.
Previously, matched suppressions were printed unconditionally if there were
unsuppressed leaks. Also, verbosity=1 no longer has the semantics of "always
print suppressions and summary".

Sergey Matveev 7237879926 [lsan] Introduce __lsan_(un)register_root_region().
Add an interface for telling LSan that a region of memory is to be treated as a
source of live pointers. Useful for code which stores pointers in mapped memory.

2013-12-17 11:11:23 +00:00
Sergey Matveev b1b8d1aa47 [lsan] Make LSan ignore memory poisoned by ASan.
Summary:
No more (potenital) false negatives due to red zones or fake stack
frames.
