1 ; Ensure that IR count remarks in the legacy pass manager work.
2 ; What this test should check for:
3 ; * Positive, nonzero sizes before/after for whole-module remarks
4 ; (It's okay to have nonzero sizes in per-function remarks, since a function
5 ; can be created/destroyed by a pass.)
7 ; * Sizes are being tracked properly across multiple remarks. E.g, if we have
8 ; original_count_1, final_count_1, and
9 ; original_count_2, final_count_2,
10 ; Then original_count_2 == final_count_1.
12 ; For these remarks, the "function" field in the YAML file doesn't matter.
13 ; Each of the testcases work by combining the output remarks with the
14 ; optimization record emit using -pass-remarks-output. This is done to prevent
15 ; test flakiness wrt instruction counts, but also ensure that the output values
16 ; are equivalent in both outputs.
