Jiri Daněk updated DISPATCH-2011:
---------------------------------
Description:
hwasan (hardware-assisted asan) is a complementary tool to the classical asan.
Both tools can catch an overlapping set of memory issues, but each has
strengths and weaknesses. HWASAN uses memory tagging (allocated memory gets
randomly assigned a "color tag", when access happens through a pointer of
different color, a failure is reported). ASAN uses buffer zones before and
after allocated memory and detects invalid accesses into these zones and into
recently freed memory.
HWASAN is designed to have much smaller memory overhead, with the original idea
being that it could be turned on by default in production (on mobile Android
devices).
Currently, in LLVM 11, HWASAN does not work to compile Dispatch. It would be
nice if Clang 12 did work. Issue needs to be reported.
