--- Comment #81 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jason Merrill <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:d2b9548f38c77edc29ab0e24e516f1fb341ecea7 commit r10-6387-gd2b9548f38c77edc29ab0e24e516f1fb341ecea7 Author: Jason Merrill <ja...@redhat.com> Date: Thu Jan 30 18:49:29 2020 -0500 c++: Reduce memory consumption for large static arrays. PR14179 and the C counterpart PR12245 are about memory consumption of very large file-scope arrays. Recently, location wrappers increased memory consumption significantly: in an array of integer constants, each one will have a location wrapper, which added up to over 500MB in the 14179 testcase. For this kind of testcase tracking these locations isn't worth the cost, so this patch turns the wrappers off after 256 elements; any array that size or larger isn't likely to be interested in the location of individual integer constants. PR c++/14179 * parser.c (cp_parser_initializer_list): Suppress location wrappers after 256 elements.
