23 // versions will not link with run-time.
25 // Changes between ABI versions:
26 // v1=>v2: added 'module_name' to __asan_global
27 // v2=>v3: stack frame description (created by the compiler)
28 // contains the function PC as the 3rd field (see
29 // DescribeAddressIfStack)
30 // v3=>v4: added '__asan_global_source_location' to __asan_global
31 // v4=>v5: changed the semantics and format of __asan_stack_malloc_ and
32 // __asan_stack_free_ functions
33 // v5=>v6: changed the name of the version check symbol
34 // v6=>v7: added 'odr_indicator' to __asan_global
35 // v7=>v8: added '__asan_(un)register_image_globals' functions for dead
36 // stripping support on Mach-O platforms
