Alexey Samsonov	50bf956f29	AddressSanitizer: fix recently introduced lint errors and broken test on Mac. ... llvm-svn: 148235	2012-01-16 12:38:09 +00:00
Alexander Potapenko	bd53f597de	This patch adds two methods, __asan_allocate_island and __asan_deallocate_island ... and switches our interceptors to using them instead of the default vm_allocate-based approach used by mach_override_ptr. To simplify the code, a fixed memory mapping is used for the allocation pool -- note that we can't mmap an arbitrary chunk of memory, because the shadow memory hasn't been mapped yet (for the reasons discussed in http://code.google.com/p/address-sanitizer/issues/detail?id=24, we cannot map the shadow earlier) The patch drops the program startup time from several second to half a second, which speeds up the execution of ASan tests noticeably. Because of the virtual memory size occupied by the programs it's hard to speed up the shutdown time, which would've also helped the tests. llvm-svn: 148116	2012-01-13 16:13:58 +00:00

Kostya Serebryany	019b76f5fd	AddressSanitizer run-time library. Not yet integrated with the compiler-rt build system, but can be built using the old makefile. See details in README.txt ... llvm-svn: 145463	2011-11-30 01:07:02 +00:00
