as a shared library on Mac OS. This will provide an alternative to
mach_override.

llvm-svn: 162091

llvm-svn: 161954

Introduce asan_intercepted_functions.h which contains the declarations wrapped functions and their wrappers.
Those declarations are going to be shared between asan_interceptors.cc and the dynamic runtime library on Mac OS.

llvm-svn: 161952

[ASan] lit tests: use nm instead of llvm-nm, until llvm-nm becomes usable on Mac. Port output test change in r161948 to lit

llvm-svn: 161951

Check for filenames and numbers to detect possible problems with asan_symbolize.py on -fPIE binaries.

llvm-svn: 161948

Fixes the problem with -PIE binaries.

llvm-svn: 161947

llvm-svn: 161946

Move the prototype of __CFInitialize to asan_mac.h so that asan_malloc_mac.cc may use it in the dynamic library mode.

llvm-svn: 161945

Export CheckFailed, asan_malloc, asan_free, asan_memalign, AsanStackTrace::CompressStack, AsanStackTrace::UncompressStack from the dynamic runtime library.

llvm-svn: 161943

Make __asan::asan_{malloc,free,memalign} globally visible, so that the dynamic version of the runtime will export them.

llvm-svn: 161942

[ASan] Port (the last one) tricky interface_test to lit, and a *huge* chunks of boilerplate to run tests for 32/64 bits and all optimization levels. Alas, lit doesn't support for loops in RUN-lines...

llvm-svn: 161941

llvm-svn: 161939

llvm-svn: 161938

llvm-svn: 161936

[ASan] port remaining output and feature tests to lit. TODO: we should in fact run most of the tests for 32/64 bits and for all optimization levels

[ASan] add __asan_set_on_error_callback into force_interface_symbols (thanks to cool test by glider@)

llvm-svn: 161756

[ASan] Add __asan_set_on_error_callback() interface function that allows user to set a callback to be called right when ASan detects an error

llvm-svn: 161754

[ASan] If ASan finds second error report, wait for some time and die (instead of running in a busy loop) to make sure ASan won't hang if it finds error while reporting an error in the same thread

when trying to free memory that actually belongs to the system purgeable zone, use malloc_zone_free(malloc_default_purgeable_zone(), ptr) instead of asan_free().

llvm-svn: 161661

Add a test checking that all the "__asan_" interface functions are present in a binary built with -dead_strip.
Fix force_interface_symbols() so that none of the interface symbols is stripped.

llvm-svn: 161582

llvm-svn: 161576

[ASan] Small fix to please tests on Windows, where stack unwinding using provided pc/bp works too bad

llvm-svn: 161575

llvm-svn: 161574

Otherwise Clang eliminates everything after the first interface symbol that is marked noreturn.

[ASan] Create new files asan_report.{h,cc} as a preparation for refactoring of ASan error reporting code.
Currently ASan reports many kinds of errors, and the code that actually prints error messages can
be found inside allocator, OS-specific files, interceptors code etc.

An example of maintenance troubles this situation causes:
There is currently an ASan interface function that registers
callback which should take the char buffer with error report printed by ASan.
This function is now broken, as one has to insert callback calls to all the places in
ASan code where the error reports are printed, surprisingly it is not only
"__asan_report_error" function...
