Expands pseudo instructions PATCHABLE_FUNCTION_ENTER and PATCHABLE_RET
into a small instruction sequence which calls into the XRay library.

[SystemZ][z/OS] z/OS ADA codegen and emission

2023-07-05T17:21:52+00:00

This patch adds support for the ADA (associated data area), doing the following:

-Creates the ADA table to handle displacements
-Emits the ADA section in the SystemZAsmPrinter
-Lowers the ADA_ENTRY node into the appropriate load instruction

[NFC][TargetParser] Remove llvm/ADT/Triple.h

2023-02-07T12:39:46+00:00

I also ran `git clang-format` to get the headers in the right order for
the new location, which has changed the order of other headers in two
files.

[SystemZ] Add support for tune-cpu attribute

2022-06-30T16:50:11+00:00

clang (like gcc) has the `-mtune=` command line option. This option
adds the `"tune-cpu"` attribute to a function. The intended functionality
is that the scheduling model of that cpu is used. E.g. `-mtune=z15 -march=z14`
generates only instructions supported on z14 but uses the scheduling model
of z15 for it.
This PR adds the infrastructure to support this.

[SystemZ] [NFC] Add SystemZELFFrameLowering and SystemZXPLINKFrameLowering classes.

2021-09-09T16:23:40+00:00

This patch adds class SystemZFrameLowering which is a SystemZ-specific class
detailing special registers used by calling conventions on the target.
SystemZELFFrameLowering and SystemZXPLINKFrameLowering implement this class
for ELF and XPLINK64 respectively. Previous functionality in SystemZFrameLowering
is moved to SystemZELFFrameLowering. SystemZXPLINKFrameLowering can then be
implemented in future patches.
