PEI should be able to use backward walk in replaceFrameIndicesBackward.

2022-11-18T14:57:34+00:00

The backward register scavenger has correct register
liveness information. PEI should leverage the backward register scavenger.

[llvm] Use std::size instead of llvm::array_lengthof

2022-09-08T15:01:53+00:00

LLVM contains a helpful function for getting the size of a C-style
array: `llvm::array_lengthof`. This is useful prior to C++17, but not as
helpful for C++17 or later: `std::size` already has support for C-style
arrays.

Change call sites to use `std::size` instead.

Revert "Rename llvm::array_lengthof into llvm::size to match std::size from C++17"

2022-01-26T15:55:53+00:00

This reverts commit ef8206320769ad31422a803a0d6de6077fd231d2.

- It conflicts with the existing llvm::size in STLExtras, which will now
  never be called.
- Calling it without llvm:: breaks C++17 compat

Rename llvm::array_lengthof into llvm::size to match std::size from C++17

2022-01-26T15:17:45+00:00

As a conquence move llvm::array_lengthof from STLExtras.h to
STLForwardCompat.h (which is included by STLExtras.h so no build
breakage expected).

[NFC][AMDGPU] Reduce includes dependencies.

2021-08-25T09:01:55+00:00

1. Splitted out some parts of R600 target to separate modules/headers.
2. Reduced some include lists in headers.
3. Found and fixed issue with override `GCNTargetMachine::getSubtargetImpl()`
   and `R600TargetMachine::getSubtargetImpl()` had different return value type
   than base class.
4. Minor forward declarations cleanup.
