11 years agoImprove cstore code generation on 64-bit sparc.
davem [Wed, 10 Apr 2013 19:41:57 +0000 (19:41 +0000)]
Improve cstore code generation on 64-bit sparc.

One major suboptimal area of the sparc back end is cstore generation
on 64-bit.

Due to the way arguments and return values of functions must be
promoted, the ideal mode for cstore's result would be DImode.

But this hasn't been done because of a fundamental limitation
of the cstore patterns.  They require a fixed mode be used for
the boolean result value.

I've decided to work around this by building a target hook which
specifies the type to use for conditional store results, and then I
use a special predicate for operans 0 in the cstore expanders so
that they still match even when we use DImode.

The default version of the target hook just does what it does now,
so no other target should be impacted by this at all.

Regstrapped on 32-bit sparc-linux-gnu and I've run the testsuite
with "-m64" to validate the 64-bit side.

First phase of unifying the computation of profile scale factors/probabilities
and the actual scaling to use rounding divides:
- Add new macro GCOV_COMPUTE_SCALE to basic-block.h to compute the scale
factor/probability via a rounding divide.
- Change all locations that already perform rounding divides (inline or via RDIV)
to use the appropriate helper: GCOV_COMPUTE_SCALE, apply_probability or
combine_probabilities.
- Change ipa-cp.c truncating divides to use rounding divides.
- Add comments to all other locations (currently using truncating divides) to
switch them to one of the helpers so they use a rounding divide.

Next phase will be to replace the locations using truncating divides, marked
with a comment here, into rounding divides via the helper methods.
