Mark functions in some tests as 'nounwind'. Generating EH info for these functions causes the tests to fail for random reasons (e.g. looking for 'or' or counting lines with asm-printer; labels count as lines.) llvm-svn: 49003

add a cl::opt override for TargetLoweringBase's JumpIsExpensive This patch is not intended to change existing codegen behavior for any target. It just exposes the JumpIsExpensive setting on the command-line to allow for easier testing and emergency overrides. Also, change the existing regression test to use FileCheck, explicitly specify the jump-is-expensive option, and use more precise checks.

[Peephole] Allow folding loads into instructions w/multiple uses (such as test64rr) Peephole opt has a one use limitation which appears to be accidental. The function being used was incorrectly documented as returning whether the def had one *user*, but instead returned true only when there was one *use*. Add a corresponding hasOneNonDbgUser helper, and adjust peephole-opt to use the appropriate one. All of the actual folding code handles multiple uses within a single instruction. That codepath is well exercised through instruction selection. Differential Revision: https://reviews.llvm.org/D63656 llvm-svn: 364336
