One of the most costly headers across the build is boyer_moore_searcher.h, which is used inside <functional>. The file is included 2499 times. Before the proposed change: **** Time summary: Compilation (10226 times): Parsing (frontend): 9479.2 s Codegen & opts (backend): 3429.0 s With the change: **** Time summary: Compilation (10196 times): Parsing (frontend): 9312.7 s Codegen & opts (backend): 3316.7 s Roughly a savings of 2.75 CPU minutes in parsing, and close to 2 CPU minutes in codegen.
