* Shuffle how lldb register contexts are built.mortimer2021-02-141-3/+2
| | | | | | | | | | | | Instead of using #if defined(__arch__) to include / exclude the entire contents of the NativeRegisterContext implementations, use a single NativeRegisterContextOpenBSD_arch which includes the right arch specific register context, and provides a dummy implementation for unsupported architectures. This allows building lldb on architectures which do not have a register context implementation so it can be used as a remote client. ok patrick@

* Implement Loongson 2F BTB bug workaround in clangvisa2020-12-011-1/+2
| | | | | | | | | | This adapts the -mfix-loongson2f-btb workaround from as(1) to LLVM/clang. Because LLVM emits machine code directly without using assembly as intermediary form, the workaround has to be applied in the compiler backend in addition to the integrated assembler.

* Add retguard for octeon/mips64.mortimer2019-10-252-3/+5
| | | | | | | | | | For this architecture we use separate retguard prologue and epilogue code for static or PIC code. In the PIC case we use some additional code before the retguard epilogue to recover the function start address and the GOT pointer in order to get the per-function random cookie. Much thanks to visa@ for suggestions and advice making it all work. ok deraadt@ visa@
