2025-04-24[TableGen] Only store direct superclasses in Record (#123072)Jay Foad
In Record only store the direct superclasses instead of all superclasses. getSuperClasses recurses to find all superclasses when necessary. This gives a small reduction in memory usage. On lib/Target/X86/X86.td I measured about 2.0% reduction in total bytes allocated (measured by valgrind) and 1.3% reduction in peak memory usage (measured by /usr/bin/time -v). --------- Co-authored-by: Min-Yih Hsu <min@myhsu.dev>
2024-10-18[LLVM][TableGen] Change all `Init` pointers to const (#112705)Rahul Joshi
This is a part of effort to have better const correctness in TableGen backends: https://discourse.llvm.org/t/psa-planned-changes-to-tablegen-getallderiveddefinitions-api-potential-downstream-breakages/81089
2024-10-02[NFC][TableGen] Change `Record::getSuperClasses` to use const Record* (#110845)Rahul Joshi
Change `Record::getSuperClasses` to return a const pointer to the superclass records. This is a part of effort to have better const correctness in TableGen backends: https://discourse.llvm.org/t/psa-planned-changes-to-tablegen-getallderiveddefinitions-api-potential-downstream-breakages/81089

2024-08-26[NFC][TableGen] Refactor JSON and detailed record emitter (#105770)Rahul Joshi
- Fix JSON and detailed record emitters to use const reference and pointers. - Fix code to use C++ structured bindings and range-based loops, including reverse() range for locations. - Eliminate `NL` define for "\n". - Change JSON emitter to populate `instance_list` in an earlier loop over superclasses instead of a separate loop. - Rename variables in JSON emitter to conform to LLVM naming conventions. - Eliminate unused headers in detailed record emitter.
