7 years ago[rtlanal] Do a better job of costing parallel sets containing flag-setting operations.
Richard Earnshaw [Fri, 30 Jun 2017 16:36:57 +0000 (16:36 +0000)]
[rtlanal] Do a better job of costing parallel sets containing flag-setting operations.

Many parallel set insns are of the form of a single set that also sets
the condition code flags.  In this case the cost of such an insn is
normally the cost of the part that doesn't set the flags, since
updating the condition flags is simply a side effect.

At present all such insns are treated as having unknown cost (ie 0)
and combine assumes that such insns are infinitely more expensive than
any other insn sequence with a non-zero cost.

This patch addresses this problem by allowing insn_rtx_cost to ignore
the condition setting part of a PARALLEL iff there is exactly one
comparison set and one non-comparison set.  If the only set operation
is a comparison we still use that as the basis of the insn cost.

* rtlanal.c (insn_rtx_cost): If a parallel contains exactly one
comparison set and one other set, use the cost of the non-comparison
set.

7 years ago[arm] Fix incorrect __ARM_ARCH_PROFILE for -march=armv7

[arm] Fix incorrect __ARM_ARCH_PROFILE for -march=armv7

ACLE explicitly states that when targetting the common subset of
ARMv7-A, ARMv7-R and ARMv7-M, the __ARM_ARCH_PROFILE macro should not
be set.  We currently set it to 'M' which is clearly erroneous.

The logic for creating this is very convoluted and also somewhat
fragile, so I've taken the opportunity to use the new CPU and
architecture definition infrastructure to record the profile for each
architecture explicitly rather than try to reconstruct it from other
data.  I think this results in a much more robust solution.

Improve Cortex-A53 shift bypass

The aarch_forward_to_shift_is_not_shifted_reg bypass always returns true

too many cases, resulting in slower execution on Cortex-A53 like reported
