a0bfbda51c C++: Improve performance by not calling getDef, but instead refer to isDefinitionInexact. This gives roughly the same tuple numbers we had with only instruction nodes. 2020-06-25 13:37:14 +02:00

5a5df4de26 Revert "Merge pull request #3419 from MathiasVP/flat-structs" 
There was unfortunately a semantic merge conflict between #3419 and
 #3587 that caused a performance regression on (at least) OpenJDK.

This reverts commit 982fb38807, reversing
changes made to b841cacb83.

687d6d2643 C++: Replace TRawInstruction() calls 
Replace most direct calls to `TRawInstruction()` with calls to `getInstructionTranslatedElement()` and `getInstructionTag()`, matching existing practice. One tiny RA diff in an inconsequential join order in `getInstructionVariable`.

c1016743a5 C++: Remove instructionOrigin() 
This noopt predicate is no longer necessary. It's equivalent to `instruction = TRawInstruction(element, tag)`, which is already materialized and has a more favorable column order anyway.

e85cc0b0c6 C++: Stop caching raw IR construction predicates 
These predicates are only used within the new single IR stage, so there's no need to cache them beyond that. RA diffs are trivial. Where previously many of the predicate on `Instruction` were inline wrappers around cached predicates from `IRConstruction`, now the predicates from `IRConstruction` get inlined into the `Instruction` predicates, and the `Instruction` predicates get materialized. The net amount of work is the same, but now it's not getting cached unnecessarily.

See https://github.com/github/codeql/pull/2272. I've added code comments in all of the places that future me will be tempted to hoist these overrides.
