// Changes between ABI versions:
// v1=>v2: added 'module_name' to __asan_global
// v2=>v3: stack frame description (created by the compiler)
// contains the function PC as the 3rd field (see
// DescribeAddressIfStack)
// v3=>v4: added '__asan_global_source_location' to __asan_global
// v4=>v5: changed the semantics and format of __asan_stack_malloc_ and
// __asan_stack_free_ functions
// v5=>v6: changed the name of the version check symbol
// v6=>v7: added 'odr_indicator' to __asan_global
// v7=>v8: added '__asan_(un)register_image_globals' functions for dead
// stripping support on Mach-O platforms
#if SANITIZER_WORDSIZE == 32 && SANITIZER_ANDROID
