2015-10-21Add a pass to back-propagate use informationRichard Sandiford1-0/+1
This patch adds a pass that collects information that is common to all uses of an SSA name X and back-propagates that information up the statements that generate X. The general idea is to use the information to simplify instructions (rather than a pure DCE) so I've simply called it gimple-ssa-backprop.c, to go with tree-ssa-forwprop.c. At the moment the only use of the pass is to remove unnecessary sign operations, so that it's effectively a global version of fold_strip_sign_ops. I'm hoping it could be extended in future to record which bits of an integer are significant. There are probably other potential uses too. A later patch gets rid of fold_strip_sign_ops. Tested on x86_64-linux-gnu, aarch64-linux-gnu and arm-linux-gnueabi. gcc/ * doc/invoke.texi (-fdump-tree-backprop, -fssa-backprop): Document. * Makefile.in (OBJS): Add gimple-ssa-backprop.o. * common.opt (fssa-backprop): New option. * fold-const.h (negate_mathfn_p): Declare. * fold-const.c (negate_mathfn_p): Make public. * timevar.def (TV_TREE_BACKPROP): New. * tree-pass.h (make_pass_backprop): Declare. * passes.def (pass_backprop): Add. * gimple-ssa-backprop.c: New file. gcc/testsuite/ * gcc.dg/tree-ssa/backprop-1.c, gcc.dg/tree-ssa/backprop-2.c, gcc.dg/tree-ssa/backprop-3.c, gcc.dg/tree-ssa/backprop-4.c, gcc.dg/tree-ssa/backprop-5.c, gcc.dg/tree-ssa/backprop-6.c: New tests.

2015-10-15PR67945: Fix oscillation between pow representationsRichard Sandiford1-0/+4
This patch fixes some fallout from my patch to move the sqrt and cbrt folding rules to match.pd. The rules included canonicalisations like: sqrt(sqrt(x))->pow(x,1/4) which in the original code was only ever done at the generic level. My patch meant that we'd do it whenever we tried to fold a gimple statement, and eventually it would win over the sincos optimisation that replaces pow(x,1/4) with sqrt(sqrt(x)). Following a suggestion from Richard B, the patch adds a new PROP_gimple_* flag to say whether fp routines have been optimised for the target. If so, match.pd should only transform calls to math functions if the result is actually an optimisation, not just an IL simplification or canonicalisation. The question then of course is: which rules are which? I've added block comments that describe the criteria I was using. A slight wart is that we need to use the cfun global to access the PROP_gimple_* flag; there's no local function pointer available. Bootstrapped & regression-tested on x86_64-linux-gnu. Also tested on powerc64-linux-gnu. gcc/ PR tree-optimization/67945 * tree-pass.h (PROP_gimple_opt_math): New property flag. * generic-match-head.c (canonicalize_math_p): New function. * gimple-match-head.c: Include tree-pass.h.
