Alan Baker 802cf053c7 Merge arithmetic with non-trivial constant operands ... Adding basis of arithmetic merging * Refactored constant collection in ConstantManager * New rules: * consecutive negates * negate of arithmetic op with a constant * consecutive muls * reciprocal of div * Removed IRContext::CanFoldFloatingPoint * replaced by Instruction::IsFloatingPointFoldingAllowed * Fixed some bad tests * added some header comments Added PerformIntegerOperation * minor fixes to constants and tests * fixed IntMultiplyBy1 to work with 64 bit ints * added tests for integer mul merging Adding test for vector integer multiply merging Adding support for merging integer add and sub through negate * Added tests Adding rules to merge mult with preceding divide * Has a couple tests, but needs more * Added more comments Fixed bug in integer division folding * Will no longer merge through integer division if there would be a remainder in the division * Added a bunch more tests Adding rules to merge divide and multiply through divide * Improved comments * Added tests Adding rules to handle mul or div of a negation * Added tests Changes for review * Early exit if no constants are involved in more functions * fixed some comments * removed unused declaration * clarified some logic Adding new rules for add and subtract * Fold adds of adds, subtracts or negates * Fold subtracts of adds, subtracts or negates * Added tests		2018-02-27 13:02:13 -05:00
