[PATCH] D43962: [GlobalISel][utils] Adding the init version of Instruction Select Testgen

[Roman Tereshin via Phabricator via llvm-commits]

rtereshin updated this revision to Diff 147646.
rtereshin added a comment.

I have:

1. Fixed IR-building code that failed to update def-use chains properly until very end of the test generation, rendering GIM_CheckSameOperands fragile and dependent on which operand was already defined / checked explicitly and which one is not
2. Started sorting machine instructions inserted in topological order explicitly (rather than implicity relying on GIM_RecordInsn's opcodes), thus a) reducing the size of the diffs in case of changes b) making GIM_CheckSameOperands less fragile (it could have created uses not dominated by defs previously)
3. Stabilized resulting vreg numbers to reduce the diffs in case of changes
