[PowerPC] don't generate hardware loop.

2022-12-20T01:32:29+00:00

If the candidate loop already has hardware loop related intrinsics,
don't generate hardware loop on PPC. PPC does not support nested
hardware loops.

[PPC] Opaque pointer migration, part 1.

2022-10-11T17:24:06+00:00

The LIT test cases were migrated with the script provided by
Nikita Popov. Due to the size of the change it is split into
several parts.

[NFC] remove explicit default value for strboolattr attribute in tests

Since d6de1e1a71406c75a4ea4d5a2fe84289f07ea3a1, no attributes is quivalent to
setting attribute to false.

[CodeGen] Generic Hardware Loop Support

2019-06-07T07:35:30+00:00

    
Patch which introduces a target-independent framework for generating
hardware loops at the IR level. Most of the code has been taken from
PowerPC CTRLoops and PowerPC has been ported over to use this generic
pass. The target dependent parts have been moved into
TargetTransformInfo, via isHardwareLoopProfitable, with
HardwareLoopInfo introduced to transfer information from the backend.
    
Three generic intrinsics have been introduced:
- void @llvm.set_loop_iterations
  Takes as a single operand, the number of iterations to be executed.
- i1 @llvm.loop_decrement(anyint)
  Takes the maximum number of elements processed in an iteration of
  the loop body and subtracts this from the total count. Returns
  false when the loop should exit.
- anyint @llvm.loop_decrement_reg(anyint, anyint)
  Takes the number of elements remaining to be processed as well as
  the maximum numbe of elements processed in an iteration of the loop
  body. Returns the updated number of elements remaining.

Adding -verify-machineinstrs option to PowerPC tests

2016-08-03T18:17:35+00:00

Currently we have a number of tests that fail with -verify-machineinstrs.
To detect this cases earlier we add the option to the testcases with the
exception of tests that will currently fail with this option. PR 27456 keeps
track of this failures.

No code review, as discussed with Hal Finkel.
