* Add round_nimm_scalar_predicate and use xBmhjl/pr69171/masterH.J. Lu2016-01-072-15/+22

* Add an rsqrt_optab and IFN_RSQRT internal functionrsandifo2015-12-031-53/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All current uses of builtin_reciprocal convert 1.0/sqrt into rsqrt. This patch adds an rsqrt optab and associated internal function for that instead. We can then pick up the vector forms of rsqrt automatically, fixing an AArch64 regression from my internal_fn patches. With that change, builtin_reciprocal only needs to handle target-specific built-in functions. I've restricted the hook to those since, if we need a reciprocal of another standard function later, I think there should be a strong preference for adding a new optab and internal function for it, rather than hiding the code in a backend. Three targets implement builtin_reciprocal: aarch64, i386 and rs6000. i386 and rs6000 already used the obvious rsqrt<mode>2 pattern names for the instructions, so they pick up the new code automatically. aarch64 needs a slight rename. mn10300 is unusual in that its native operation is rsqrt, and sqrt is approximated as 1.0/rsqrt. The port also uses rsqrt<mode>2 for the rsqrt pattern, so after the patch we now pick it up as a native operation. Two other ports define rsqrt patterns: sh and v850. AFAICT these patterns aren't currently used, but I think the patch does what the authors of the patterns would have expected. There's obviously some risk of fallout though.

* PR 68432: Add a target hook to control size/speed optab choicesrsandifo2015-12-022-68/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
