[PowerPC] Define SchedModel for Power8

2023-09-08T07:43:21+00:00

PowerPC subtargets prior to Power9 use the 'legacy' itinerary way to
provide scheduling information. This patch re-writes the tablegen file
to define the scheduling information in the new SchedModel way, which
can bring improvements to some benchmarks.

[PowerPC][test] Add explicit dso_local to definitions in ELF static relocation model tests

2020-12-30T18:32:34+00:00

TargetMachine::shouldAssumeDSOLocal currently implies dso_local for such definitions.

Adding explicit dso_local makes these tests align with the clang -fpic behavior
and allow the removal of the TargetMachine::shouldAssumeDSOLocal special case.

Rewrite preemption.ll to dsolocal-static.ll and dsolocal-pic.ll, and add
"PIC Level" metadata.

[PowerPC] Replace the Post RA List Scheduler with the Machine Scheduler

2018-07-04T18:54:25+00:00

  We want to run the Machine Scheduler instead of the List Scheduler after RA.
  Checked with a performance run on a Power 9 machine with SPEC 2006 and while
  some benchmarks improved and others degraded the geomean was slightly improved
  with the Machine Scheduler.

[CodeGen] Unify MBB reference format in both MIR and debug output

2017-12-04T17:18:51+00:00

As part of the unification of the debug format and the MIR format, print
MBB references as '%bb.5'.

The MIR printer prints the IR name of a MBB only for block definitions.

[PowerPC] Recommit r314244 with refactoring and off by default

2017-11-30T13:39:10+00:00

This re-commits everything that was pulled in r314244. The transformation
is off by default (patch to enable it to follow). The code is refactored
to have a single entry-point and provide fine-grained control over patterns
that it selects. This patch also fixes the bugs in the original code.

Everything that failed with the original patch has been re-tested with this
patch (with the transformation turned on). So the patch to turn this on is
soon to follow.
