Subject: [PATCH] [Coro] Use DebugInfoCache to speed up cloning in
CoroSplitPass
Summary:
We can use a DebugInfoFinder from DebugInfoCache which is already primed on a compile unit to speed
up collection of global debug info.
The pass could likely be another 2x+ faster if we avoid rebuilding the set of global debug
info. This needs further massaging of CloneFunction and ValueMapper, though, and can be done
incrementally on top of this.
Comparing performance of CoroSplitPass at various points in this stack, this is anecdata from a sample
cpp file compiled with full debug info:
| | Baseline | IdentityMD set | Prebuilt GlobalDI | Cached CU DIFinder (cur.) |
|-----------------+----------+----------------+-------------------+---------------------------|
| CoroSplitPass | 306ms | 221ms | 68ms | 17ms |
| CoroCloner | 101ms | 72ms | 0.5ms | 0.5ms |
| CollectGlobalDI | - | - | 63ms | 13ms |
|-----------------+----------+----------------+-------------------+---------------------------|
| Speed up | 1x | 1.4x | 4.5x | 18x |
Test Plan:
ninja check-llvm-unit
ninja check-llvm
Compiled a sample cpp file with time trace to get the avg. duration of the pass and inner scopes.
