--- Comment #13 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The trunk branch has been updated by Andi Kleen <a...@gcc.gnu.org>: https://gcc.gnu.org/g:ae814afad900edf1f19850985614398e0875618c commit r15-7326-gae814afad900edf1f19850985614398e0875618c Author: Andi Kleen <a...@gcc.gnu.org> Date: Wed Dec 25 11:54:13 2024 -0800 Add tunables for input buffer The input machinery to read the source code independent of the lexer has a range of hard coded maximum array sizes that can impact performance. Make them tunable. input.cc is part of libcommon so it cannot direct access params without a level of indirection. gcc/ChangeLog: PR preprocessor/118168 * input.cc (file_cache::tune): New function. * input.h (class file_cache): Make tunables non const. * params.opt: Add new tunables. * toplev.cc (toplev::main): Initialize input buffer context tunables.
