* compiler-rt: Remove .cc from all lit config filesNico Weber2019-08-051-1/+1
| | | | | | All cc files have been renamed to cpp now. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@367911 91177308-0d34-0410-b5e6-96231b3b80d8
* [compiler-rt] Rename lit.*.cfg.* -> lit.*.cfg.py.*Reid Kleckner2019-06-273-3/+3
| | | | | | | | | | | | | These lit configuration files are really Python source code. Using the .py file extension helps editors and tools use the correct language mode. LLVM and Clang already use this convention for lit configuration, this change simply applies it to all of compiler-rt.

* Delete x86_64 ShadowCallStack supportVlad Tsyrklevich2019-03-076-30/+7
| | | | | | | | | | | | | | | | | | | | | Summary: ShadowCallStack on x86_64 suffered from the same racy security issues as Return Flow Guard and had performance overhead as high as 13% depending on the benchmark. x86_64 ShadowCallStack was always an experimental feature and never shipped a runtime required to support it, as such there are no expected downstream users.

* [scs] Disable negative test in shadowcallstack.Evgeniy Stepanov2018-06-291-9/+1
| | | | | | | | The test checks that scs does NOT work correctly w/o runtime support. That's a strange thing to test, and it is also flaky, because things may just work if x18 happens to point to a writable page. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@335982 91177308-0d34-0410-b5e6-96231b3b80d8

* Add simple runtime tests for shadowcallstackVlad Tsyrklevich2018-04-046-0/+117
Summary: ShadowCallStack does not yet have a runtime provided by compiler-rt, but this change includes simple tests that make use of a very minimal runtime in test/shadowcallstack/minimal_runtime.h Reviewers: pcc, kcc, delcypher, eugenis, filcab Reviewed By: pcc Subscribers: kubamracek, mgorny, delcypher, llvm-commits, #sanitizers, kcc Differential Revision: https://reviews.llvm.org/D44803 git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@329210 91177308-0d34-0410-b5e6-96231b3b80d8
