dacfa24f - Delete 'llvm.asan.globals' for global metadata.

Mon, 27 Jun 2022 21:40:03 +0000

Delete 'llvm.asan.globals' for global metadata.Now that we have the sanitizer metadata that is actually on the globalvariable, and now that we use debuginfo in order to do symbolization ofglobals, we can delete the 'llvm.asan.globals' IR synthesis.This patch deletes the 'location' part of the __asan_global that'sembedded in the binary as well, because it's unnecessary. This savesabout ~1.7% of the optimised non-debug with-asserts clang binary.Reviewed By: vitalybukaDifferential Revision: https://reviews.llvm.org/D127911 List of files: /llvm-project-15.0.7/llvm/test/Instrumentation/AddressSanitizer/global_metadata_array.ll

dbc641de - [sanitizer] Reduce redzone size for small size global objects

Thu, 20 May 2021 02:18:49 +0000

[sanitizer] Reduce redzone size for small size global objectsCurrently 1 byte global object has a ridiculous 63 bytes redzone.This patch reduces the redzone size to be less than 32 if the size of global object is less than or equal to half of 32 (the minimal size of redzone).A 12 bytes object has a 20 bytes redzone, a 20 bytes object has a 44 bytes redzone.Reviewed By: MaskRay, #sanitizers, vitalybukaDifferential Revision: https://reviews.llvm.org/D102469 List of files: /llvm-project-15.0.7/llvm/test/Instrumentation/AddressSanitizer/global_metadata_array.ll

[NFC] Disallow unused prefixes under llvm/testThis patch sets the default for llvm tests, with the exception of testsunder Reduce, because quite a few of them use 'FileCheck' as parameterto a tool, and including a flag as that parameter would complicatematters.The rest of the patch undo-es the lit.local.cfg changes we progressivelyintroduced as temporary measure to avoid regressions under variousdirectories.Differential Revision: https://reviews.llvm.org/D95111 List of files: /llvm-project-15.0.7/llvm/test/Instrumentation/AddressSanitizer/global_metadata_array.ll

7c2f2762 - [NewPM][ASan] Make ASan tests work under NPM

Sat, 18 Jul 2020 00:49:46 +0000

[NewPM][ASan] Make ASan tests work under NPMUnder NPM, the asan-globals-md analysis is required but cannot be runwithin the asan function pass due to module analyses not being able torun from a function pass. So this pins all tests using "-asan" to thelegacy PM and adds a corresponding RUN line with-passes='require,function(asan)'.Now all tests in Instrumentation/AddressSanitizer pass when-enable-new-pm is by default on.Tests were automatically converted using the following python script andfailures were manually fixed up.import sysfor i in sys.argv: with open(i, 'r') as f: s = f.read() with open(i, 'w') as f: for l in s.splitlines(): if "RUN:" in l and ' -asan -asan-module ' in l and '\\' not in l: f.write(l.replace(' -asan -asan-module ', ' -asan -asan-module -enable-new-pm=0 ')) f.write('\n') f.write(l.replace(' -asan -asan-module ', " -passes='require,function(asan),module(asan-module)' ")) f.write('\n') elif "RUN:" in l and ' -asan ' in l and '\\' not in l: f.write(l.replace(' -asan ', ' -asan -enable-new-pm=0 ')) f.write('\n') f.write(l.replace(' -asan ', " -passes='require,function(asan)' ")) f.write('\n') else: f.write(l) f.write('\n')See https://bugs.llvm.org/show_bug.cgi?id=46611.Reviewed By: vitalybukaDifferential Revision: https://reviews.llvm.org/D83921 List of files: /llvm-project-15.0.7/llvm/test/Instrumentation/AddressSanitizer/global_metadata_array.ll

d414e1bb - [asan] Prevent folding of globals with redzones

Thu, 20 Dec 2018 00:30:18 +0000

[asan] Prevent folding of globals with redzonesSummary:ICF prevented by removing unnamed_addr and local_unnamed_addr for all sanitizedglobals.Also in general unnamed_addr is not valid here as address now is important forODR violation detector and redzone poisoning.Before the patch ICF on globals caused:1. false ODR reports when we register global on the same address more than once2. globals buffer overflow if we fold variables of smaller type inside of largetype. Then the smaller one will poison redzone which overlaps with the larger one.Reviewers: eugenis, pccSubscribers: hiraditya, llvm-commitsDifferential Revision: https://reviews.llvm.org/D55857llvm-svn: 349706 List of files: /llvm-project-15.0.7/llvm/test/Instrumentation/AddressSanitizer/global_metadata_array.ll
