11 years ago[PowerPC] Skeletal FastISel support for 64-bit PowerPC ELF.

[PowerPC] Skeletal FastISel support for 64-bit PowerPC ELF.

This is the first of many upcoming patches for PowerPC fast
instruction selection support.  This patch implements the minimum
necessary for a functional (but extremely limited) FastISel pass.  It
allows the table-generated portions of the selector to be created and
used, but in most cases selection will fall back to the DAG selector.
None of the block terminator instructions are implemented yet, and
most interesting instructions require some special handling.
Therefore there aren't any new test cases with this patch.  There will
be quite a few tests coming with future patches.

This patch adds the make/CMake support for the new code (including
tablegen -gen-fast-isel) and creates the FastISel object for PPC64 ELF
only.  It instantiates the necessary virtual functions
(TargetSelectInstruction, TargetMaterializeConstant,
TargetMaterializeAlloca, tryToFoldLoadIntoMI, and FastLowerArguments),
but of these, only TargetMaterializeConstant contains any useful
implementation.  This is present since the table-generated code
requires the ability to materialize integer constants for some
instructions.

This patch has been tested by building and running the
projects/test-suite code with -O0.  All tests passed with the
exception of a couple of long-running tests that time out using -O0
code generation.

Chandler Carruth [Mon, 29 Jul 2013 09:06:53 +0000 (09:06 +0000)]
Teach the AllocaPromoter which is wrapped around the SSAUpdater
infrastructure to do promotion without a domtree the same smarts about
looking through GEPs, bitcasts, etc., that I just taught mem2reg about.
This way, if SROA chooses to promote an alloca which still has some
noisy instructions this code can cope with them.

I've not used as principled of an approach here for two reasons:
1) This code doesn't really need it as we were already set up to zip
   through the instructions used by the alloca.
2) I view the code here as more of a hack, and hopefully a temporary one.

The SSAUpdater path in SROA is a real sore point for me. It doesn't make
a lot of architectural sense for many reasons:
- We're likely to end up needing the domtree anyways in a subsequent
  pass, so why not compute it earlier and use it.
- In the future we'll likely end up needing the domtree for parts of the
  inliner itself.
- If we need to we could teach the inliner to preserve the domtree. Part
  of the re-work of the pass manager will allow this to be very powerful
  even in large SCCs with many functions.
- Ultimately, computing a domtree has gotten significantly faster since
  the original SSAUpdater-using code went into ScalarRepl. We no longer
  use domfrontiers, and much of domtree is lazily done based on queries
  rather than eagerly.
- At this point keeping the SSAUpdater-based promotion saves a total of
  0.7% on a build of the 'opt' tool for me. That's not a lot of
  performance given the complexity!

So I'm leaving this a bit ugly in the hope that eventually we just
remove all of this nonsense.

I can't even readily test this because this code isn't reachable except
through SROA. When I re-instate the patch that fast-tracks allocas
already suitable for promotion, I'll add a testcase there that failed
before this change. Before that, SROA will fix any test case I give it.

that module. But here, we're in isel and don't really want to do that.

on either inside the Clang/LLVM code base.

This patch makes sure we always check for both variants.  In addition,
it fixes one unnecessary check in lib/Target/PowerPC/PPCJITInfo.cpp.
(At least one of __ppc__ and __powerpc__ should always be defined when
compiling for a PowerPC target, no matter which compiler is used, so
testing for them is unnecessary.)

There are some places in the compiler that check for other variants,
like __POWERPC__ and _POWER, and I have left those in place.  There is
no need to add them elsewhere.  This seems to be in Apple-specific
code, and I won't take a chance on breaking it.

There is no intended change in behavior; thus, no test cases are
added.

units, but without actually splitting the DIEs.
