All patches are together run through the gcc and g++ test-suites to check ASAN results for mipsisa32r2el-linux-gnu. As of r258635 those results are on par with those for arm-linux-gnueabihf, so without delay I present the current state. Maybe it's non-intrusive enough to be ok for gcc-8? MIPS maintainers (and interested party) CC:ed.
For use with -fsanitize=address, you'll need a non-ancient glibc or equivalent (2002-ish), one that iterates on ELF headers for the EH info at exception time (rather, doesn't call __register_frame_info or __register_frame_info_bases at startup, ending up calling malloc/free) or else Asan will try to instrument the call to free and hang on a lock for eternity (or dies on a signal). But that's no different than for other ports, AFAIU. So, ok to commit? brgds, H-P
