--- Comment #5 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:3be762c2ed79e36b9c8faaea2be04725c967a34e commit r12-2293-g3be762c2ed79e36b9c8faaea2be04725c967a34e Author: Jakub Jelinek <ja...@redhat.com> Date: Wed Jul 14 10:22:50 2021 +0200 godump: Fix -fdump-go-spec= reproduceability issue [PR101407] pot_dummy_types is a hash_set from whose traversal the code prints some type lines. hash_set normally uses default_hash_traits which for pointer types (the hash set hashes const char *) uses pointer_hash which hashes the addresses of the pointers except of the least significant 3 bits. With address space randomization, that results in non-determinism in the -fdump-go-specs= generated file, each invocation can have different order of the lines emitted from pot_dummy_types traversal. This patch fixes it by hashing the string contents instead to make the hashes reproduceable. 2021-07-14 Jakub Jelinek <ja...@redhat.com> PR go/101407 * godump.c (godump_str_hash): New type. (godump_container::pot_dummy_types): Use string_hash instead of ptr_hash in the hash_set.
