This should enableeasier experimentation with HWASan on x86_64 platforms.Currently stack, global, and secondary heap tagging are unsupported.Only primary heap allocations get tagged.Note that aliasing mode will not work properly in the presence offork(), since heap memory will be shared between the parent and childprocesses. This mode is non-ideal; we expect Intel LAM to enable fullHWASan support on x86_64 in the future.Reviewed By: vitalybuka, eugenisDifferential Revision: https://reviews.llvm.org/D98875 List of files: /llvm-project-15.0.7/compiler-rt/test/hwasan/TestCases/Posix/posix_memalign-alignment.cpp Thu, 25 Mar 2021 13:34:25 +0000 Matt Morehouse <mascasa@google.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/compiler-rt/test/hwasan/TestCases/Posix/posix_memalign-alignment.cpp#c8ef98e5 Revert "[HWASan] Use page aliasing on x86_64."This reverts commit 63f73c3eb9716256ab8dbb868e16d08a88636cba due tobreakage on aarch64 without TBI.

Since we can't relyon the operating system to be able to cope with these addresses, we need to untagthem before passing them to the operating system. This change introduces a macrothat does so and uses it everywhere it is needed.Differential Revision: https://reviews.llvm.org/D65768llvm-svn: 367938 List of files: /llvm-project-15.0.7/compiler-rt/test/hwasan/TestCases/Posix/posix_memalign-alignment.cpp Mon, 05 Aug 2019 21:46:10 +0000 Peter Collingbourne <peter@pcc.me.uk> http://172.16.0.5:8080/history/llvm-project-15.0.7/compiler-rt/test/hwasan/TestCases/Posix/posix_memalign-alignment.cpp#2f7d11be More follow-up to r367851llvm-svn: 367856 List of files: /llvm-project-15.0.7/compiler-rt/test/hwasan/TestCases/Posix/posix_memalign-alignment.cpp Mon, 05 Aug 2019 13:27:37 +0000 Nico Weber <nicolasweber@gmx.de> http://172.16.0.5:8080/history/llvm-project-15.0.7/compiler-rt/test/hwasan/TestCases/Posix/posix_memalign-alignment.cpp#53770e78 compiler-rt: Rename cc files in test/hwasan/TestCases subdirectories as wellShould've been part of r367849.llvm-svn: 367851 List of files: /llvm-project-15.0.7/compiler-rt/test/hwasan/TestCases/Posix/posix_memalign-alignment.cpp Mon, 05 Aug 2019 13:12:23 +0000 Nico Weber <nicolasweber@gmx.de>
