--- Comment #1 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Ian Lance Taylor <i...@gcc.gnu.org>: https://gcc.gnu.org/g:acf83db025cfd4a67724838e9dbd19813f4f5960 commit r11-2559-gacf83db025cfd4a67724838e9dbd19813f4f5960 Author: Ian Lance Taylor <i...@golang.org> Date: Mon Aug 3 18:23:39 2020 -0700 compiler: delete lowered constant strings If we lower a constant string operation in a Binary_expression, delete the strings. This is safe because constant strings are always newly allocated. This is a hack to use much less memory when compiling the new time/tzdata package, which has a file that contains the sum of over 13,000 constant strings. We don't do this for numeric expressions because that could cause us to delete an Iota_expression. We should have a cleaner approach to memory usage some day. Fixes PR go/96450
