For the package github.com/microsoft/typescript-go/internal/checker, compilation currently spends most of its time in escape analysis. Here, we re-order work to be more efficient when analyzing many locations, and delay visiting some locations to prioritize locations that might be more likely to reach a terminal point of reaching the heap and possibly reduce the count of intermediate states for each location. Action graph reported build times show roughly a 5x improvement for compilation of the typescript-go/internal/checker package: go1.24.0: 91.792s cl-657179-ps1: 17.578s with timing via: go build -a -debug-actiongraph=/tmp/actiongraph-cl-657179-ps1 -v github.com/microsoft/typescript-go/internal/checker There are some additional adjustments to make here, including we can consider a follow-on CL I have that parallelizes the operations of the core loop, but this seems to be a nice win as is, and my understanding is the desire is to merge this as it stands.
