2016-05-02Simplify cst_and_fits_in_hwiRichard Sandiford1-7/+2
While looking at the use of cst_and_fits_in_hwi in tree-ssa-loop-ivopts.c, I had difficulty working out what the function actually tests. The final NUNITS check seems redundant, since it asks about the number of HWIs in the _unextended_ constant. We've already checked that the unextended constant has no more than HOST_BITS_PER_WIDE_INT bits, so the length must be 1. I think this was my fault, sorry.

2015-12-02PR 68432: Add a target hook to control size/speed optab choicesRichard Sandiford1-1/+2
The problem in the PR is that some i386 optabs FAIL when optimising for size rather than speed. The gimple level generally needs access to this information before calling the generator, so this patch adds a new hook to say whether an optab should be used when optimising for size or speed. It also has a "both" option for cases where we want code that is optimised for both size and speed. I've passed the optab to the target hook because I think in most cases that's more useful than the instruction code. We could pass both if there's a use for it though. At the moment the match-and-simplify code doesn't have direct access to the target block, so for now I've used "both" there.
