10 years agoRecognize ValueType operands in source patterns for fast-isel.
Bill Schmidt [Wed, 22 May 2013 20:45:11 +0000 (20:45 +0000)]
Recognize ValueType operands in source patterns for fast-isel.

Currently the fast-isel table generator recognizes registers, register
classes, and immediates for source pattern operands.  ValueType
operands are not recognized.  This is not a problem for existing
targets with fast-isel support, but will not work for targets like
PowerPC and SPARC that use types in source patterns.

The proposed patch allows ValueType operands and treats them in the
same manner as register classes.  There is no convenient way to map
from a ValueType to a register class, but there's no need to do so.
The table generator already requires that all types in the source
pattern be identical, and we know the register class of the output
operand already.  So we just assign that register class to any
ValueType operands we encounter.

No functional effect on existing targets.  Testing deferred until the
PowerPC target implements fast-isel.

10 years agoChange some PowerPC PatLeaf definitions to ImmLeaf for fast-isel.
Bill Schmidt [Wed, 22 May 2013 20:09:24 +0000 (20:09 +0000)]
Change some PowerPC PatLeaf definitions to ImmLeaf for fast-isel.

Using PatLeaf rather than ImmLeaf when defining immediate predicates
prevents simple patterns using those predicates from being recognized
for fast instruction selection.  This patch replaces the immSExt16
PatLeaf predicate with two ImmLeaf predicates, imm32SExt16 and
imm64SExt16, allowing a few more patterns to be recognized (ADDI,
ADDIC, MULLI, ADDI8, and ADDIC8).  Using the new predicates does not
help for LI, LI8, SUBFIC, and SUBFIC8 because these are rejected for
other reasons, but I see no reason to retain the PatLeaf predicate.

No functional change intended, and thus no test cases yet.  This is
preliminary work for enabling fast-isel support for PowerPC.  When
that support is ready, we'll be able to test this function.

[SystemZ] Rename PSW to CC

Addresses a review comment from Ulrich Weigand.  No functional change intended.

I'm not sure whether the old TODO that this patch touches still holds,
but that's something we'd get to when adding a targetted scheduling
description.

10 years ago[SystemZ] Fix thinko in long branch pass
Richard Sandiford [Wed, 22 May 2013 09:57:57 +0000 (09:57 +0000)]
[SystemZ] Fix thinko in long branch pass

The original version of the pass could underestimate the length of a backward
branch in cases like:

    alignment to N bytes or more
    ...
    relaxable branch A
    ...
 foo: (aligned to M<N bytes)
    ...
 bar: (aligned to N bytes)
    ...
    relaxable branch B to foo

We don't add any misalignment gap for "bar" because N bytes of alignment
had already been reached earlier in the function.  In this case, assuming
that A is relaxed can push "foo" closer to "bar", and make B appear to be
in range.  Similar problems can occur for forward branches.

I don't think it's possible to create blocks with mixed alignments as
things stand, not least because we haven't yet defined getPrefLoopAlignment()
for SystemZ (that would need benchmarking).  So I don't think we can test
this yet.

Thanks to Rafael Espíndola for spotting the bug.
