* Update the file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-191-4/+3
| | | | | | | | | | | | | | | | | to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636
* [Sanitizers] New sanitizer API to purge allocator quarantine.Alex Shlyapnikov2017-10-231-0/+3
| | | | | | | | | | | | | | | | Summary: Purging allocator quarantine and returning memory to OS might be desired between fuzzer iterations since, most likely, the quarantine is not going to catch bugs in the code under fuzz, but reducing RSS might significantly prolong the fuzzing session.

* [sanitizer] Add list of symbols exported in sanitizers' interface.Marcos Pividori2017-01-311-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Add a new auxiliary file to each sanitizer: sanitizer_interface.inc, listing all the functions exported, with the macros: INTERFACE_FUNCTION() and INTERFACE_WEAK_FUNCTION(). So, when we need to define or repeat a procedure for each function in the sanitizer's interface, we can define the macros and include that header. In particular, these files are needed for Windows, in the nexts commits. Also, this files could replace the existing files: weak_symbols.txt for Apple. Instead of reading weak_symbols.txt to get the list of weak symbols, we could read the file sanitizer_interface.inc and consider all the symbols included with the macro INTERFACE_WEAK_FUNCTION(Name). In this commit, I only include these files to the sanitizers that work on Windows. We could do the same for the rest of the sanitizers when needed. I updated tests for: Linux, Darwin and Windows. If a new function is exported but is not present in the interface list, the tests "interface_symbols_[darwin|windows|linux].c" fail. Also, I remove the comments: "/* OPTIONAL */" which are not required any more, because we use the macro: INTERFACE_WEAK_FUNCTION() for weak functions.

* Generalize sanitizer allocator public interface.Alexey Samsonov2014-07-071-0/+38
Introduce new public header <sanitizer/allocator_interface.h> and a set of functions __sanitizer_get_ownership(), __sanitizer_malloc_hook() etc. that will eventually replace their tool-specific equivalents (__asan_get_ownership(), __msan_get_ownership() etc.). Tool-specific functions are now deprecated and implemented as stubs redirecting to __sanitizer_ versions (which are implemented differently in each tool). Replace all uses of __xsan_ versions with __sanitizer_ versions in unit and lit tests. llvm-svn: 212469
