Ravi Kandhadai	8b217afcaf	[Const Evaluator] Fix a minor bug in the copy constructor deletion of ... `ConstExprStepEvaluator`.	2019-05-14 12:09:57 -07:00
Ravi Kandhadai	b0e56f70f9	[Const evaluator] Enable stepwise constant evaluator to skip ... instructions without evaluating them while conservatively accounting for the effects of the skipped instructions on the interpreter state.	2019-04-30 15:36:29 -07:00
Ravi Kandhadai	55e82004a2	[const evaluator] Expose the step-wise constant evaluation mode ... (also referred to as flow-sensitive mode) so that the evaluator can be used by clients to constant evaluate instructions in a SILFunction body one by one following the flow of control.	2019-04-17 18:12:17 -07:00
Ravi Kandhadai	bb7363da2e	[const evaluator] Parameterize allocation of symbolic values in the ... constant interpreter. Based on this, change to a short-lived bump allocator for storing symbolic values in the pass that checks #assert.	2019-04-09 13:56:21 -07:00
Marc Rasi	44d7cdd4e6	constant interpreter: basic integer operations ... Implements a constant interpreter that can deal with basic integer operations. Summary of the features that it includes: * builtin integer values, and builtin integer insts * struct and tuple values, and insts that construct and extract them (necessary to use stdlib integers) * function referencing and application (necessary to call stdlib integer functions) * error handling data structures and logic, for telling you why your value is not evaluatable * metatype values (not necessary for integers, but it's only a few extra lines, so I thought it would be more trouble than it's worth to put them in a separate PR) * conditional branches (ditto)	2018-11-26 14:27:10 -08:00
