GCC already can do this, add this support to Clang as well. Use RISCVTargetLowering and GCC's s390_return_addr_rtx() as inspiration. Add tests based on what GCC is emitting.	2023-10-18 19:05:31 +02:00

[SystemZ] Support builtin_{frame,return}_address() with non-zero argument (#69405 )

When the code is built with -mbackchain, it is possible to retrieve the
caller's frame and return addresses. GCC already can do this, add this
support to Clang as well. Use RISCVTargetLowering and GCC's
s390_return_addr_rtx() as inspiration. Add tests based on what GCC is
emitting.

[SystemZ] Support llvm.frameaddress/llvm.returnaddress intrinsics

Enable the SystemZ back-end to lower FRAMEADDR and RETURNADDR, which
previously would cause the back-end to crash.  Currently, only a
frame count of zero is supported.
