*	[sanitizer_common] Always use posix_spawn on Darwin	Julian Lettner	2019-08-15	1	-1/+2
\| \| \| \| \| \| \| \| \| \| \| \| \|	On Darwin we have two external symbolizers: atos and llvm-symbolizer. atos was changed to use posix_spawn (instead of fork+execv) in a previous commit [1]. Let's use posix_spawn for llvm-symbolizer as well. Our hope is that eventually we can transition to posix_spawn on other platforms too. [1] 399408a92f1dbbefeb708f718b0d8eb62dfa9f09 llvm-svn: 369021
*	[sanitizer_common] Replace forkpty with posix_spawn on Darwin	Julian Lettner	2019-08-15	1	-2/+2
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	On Darwin, we currently use forkpty to communicate with the "atos" symbolizer. There are several problems that fork[pty] has, e.g. that after fork, interceptors are still active and this sometimes causes crashes or hangs. This is especially problematic for TSan, which uses interceptors for OS-provided locks and mutexes, and even Libc functions use those. This patch replaces forkpty with posix_spawn on Darwin. Since posix_spawn doesn't fork (at least on Darwin), the interceptors are not a problem. Another benefit is that we'll handle post-fork failures (e.g. sandbox disallows "exec") gracefully now.

*	compiler-rt: Rename .cc file in lib/sanitizer_common to .cpp	Nico Weber	2019-07-31	1	-0/+556
	See https://reviews.llvm.org/D58620 for discussion, and for the commands I ran. In addition I also ran for f in $(svn diff \| diffstat \| grep .cc \| cut -f 2 -d ' '); do rg $f . ; done and manually updated (many) references to renamed files found by that. llvm-svn: 367463
