Tobias Hieta	f98ee40f4b	[NFC][Py Reformat] Reformat python files in the rest of the dirs ... This is an ongoing series of commits that are reformatting our Python code. This catches the last of the python files to reformat. Since they where so few I bunched them together. Reformatting is done with `black`. If you end up having problems merging this commit because you have made changes to a python file, the best way to handle that is to run git checkout --ours <yourfile> and then reformat it with black. If you run into any problems, post to discourse about it and we will try to help.

Paul Kirth	aa1d2693c2	[CodeGen][RISCV] Change Shadow Call Stack Register to X3 ... ShadowCallStack implementation uses s2 register on RISC-V, but that choice is problematic for reasons described in: https://lists.riscv.org/g/sig-toolchains/message/544, https://github.com/riscv-non-isa/riscv-elf-psabi-doc/issues/370, and https://github.com/google/android-riscv64/issues/72 The concern over the register choice was also brought up in https://reviews.llvm.org/D84414. https://reviews.llvm.org/D84414#2228666 said: ``` "If the register choice is the only concern about this work, then I think we can probably land it as-is and fixup the register choice if we see major drawbacks later. Yes, it's an ABI issue, but on the other hand the shadow call stack is not a standard ABI anyway."" ``` Since we have now found a sufficient reason to fixup the register choice, we should go ahead and update the implementation. We propose using x3(gp) which is now the platform register in the RISC-V ABI.

Nico Weber	307beb13af	compiler-rt: Remove .cc from all lit config files ... All cc files have been renamed to cpp now. llvm-svn: 367911	2019-08-05 19:25:35 +00:00
Reid Kleckner	8007ff1ab1	[compiler-rt] Rename lit.*.cfg.* -> lit.*.cfg.py.* ... 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.
