Louis Dionne	6fd55bba61	[libunwind] Add a from-scratch config for running libunwind tests ... Running tests for libunwind is a lot simpler than running tests for libc++, so a simple Lit config file is sufficient. The benefit is that we disentangle the libunwind test configuration from the libc++ and libc++abi test configuration. The setup was too complicated, which led to some bugs (notably we were running against the system libunwind on Apple platforms).

Louis Dionne	60fe1f59d0	[runtimes][ci] Run the tests for libunwind in the CI ... We should arguably have always been doing that. The state of libunwind is quite sad, so this commit adds several XFAILs to make the CI pass. We need to investigate why so many tests are not passing in some configurations, but I'll defer that to folks who actually work on libunwind for lack of bandwidth.

Daniel Kiss	f5b997e6b7	[Unwind] Harmonise exception class for EHABI spec. ... EHABI defines the exception class as char[8] instead of uint64_t [1]. For ABI compatibility the ABI the definition needs to be updated.

Daniel Kiss	db126ae243	[Arm][Unwind][libc++abi] Add _Unwind_ForcedUnwind to EHABI. ... _Unwind_ForcedUnwind is not mandated by the EHABI but for compatibilty reasons adding so the interface to higher layers would be the same. Dropping EHABI specific _Unwind_Stop_Fn definition since it is not defined by EHABI. Reviewed By: MaskRay Differential Revision: https://reviews.llvm.org/D89570	2021-08-11 10:15:53 +02:00
