Michael Maitland	67beebfcb9	[TableGen][SubtargetEmitter] Refactor hasReadOfWrite to CodeGenProcModel (#92032) ... SubtargetEmitter::GenSchedClassTables takes a CodeGenProcModel, but calls hasReadOfWrite which loops over all ProcModels. We move hasReadOfWrite to CodeGenProcModel and remove the loop over all ProcModels. This leads to a 144% speedup on the RISC-V backend of our downstream.	2024-05-14 17:15:19 -04:00
Pierre van Houtryve	fa3d789df1	[RFC][TableGen] Restructure TableGen Source (#80847) ... Refactor of the llvm-tblgen source into: - a "Basic" library, which contains the bare minimum utilities to build `llvm-min-tablegen` - a "Common" library which contains all of the helpers for TableGen backends. Such helpers can be shared by more than one backend, and even unit tested (e.g. CodeExpander is, maybe we can add more over time) Fixes #80647	2024-03-25 09:40:35 +01:00
