Arthur Eubanks 15ba588d6d [test] Migrate '-analyze -cost-model' to '-passes=print<cost-model>' 2022-02-09 15:42:16 -08:00
Ulrich Weigand 819c1651f7 [SystemZ] Support z15 processor name
The recently announced IBM z15 processor implements the architecture
already supported as "arch13" in LLVM.  This patch adds support for
"z15" as an alternate architecture name for arch13.

The patch also uses z15 in a number of places where we used arch13
as long as the official name was not yet announced.

Ulrich Weigand 0f0a8b7784 [SystemZ] Add support for new cpu architecture - arch13
This patch series adds support for the next-generation arch13
CPU architecture to the SystemZ backend.

This includes:
- Basic support for the new processor and its features.
- Assembler/disassembler support for new instructions.
- CodeGen for new instructions, including new LLVM intrinsics.
- Scheduler description for the new processor.
- Detection of arch13 as host processor.

Note: No currently available Z system supports the arch13
architecture.  Once new systems become available, the
official system name will be added as supported -march name.

Jonas Paulsson 5da8e432b9 [SystemZ::TTI] Return zero cost for scalar load/store connected with a bswap.
Since byte-swapping loads and stores are supported, a 'load -> bswap' or
'bswap -> store' sequence should have the cost of one.

Jonas Paulsson 96782c2c0b [SystemZTTIImpl] Give correct cost values for vector bswap intrinsics.
Implement getIntrinsicInstrCost() and return costs reflecting that bswap can
be done with a vperm per vector register.
