Hi! While studying the TYPE_CANONICAL/TYPE_STRUCTURAL_EQUALITY_P stuff, I've noticed some nits in comments, the following patch fixes them.
Bootstrapped/regtested on x86_64-linux and i686-linux, ok for trunk? 2024-04-16 Jakub Jelinek <ja...@redhat.com> * tree.cc (array_type_nelts): Ensure 2 spaces after . in comment instead of just one. (build_variant_type_copy): Likewise. (tree_check_failed): Likewise. (build_atomic_base): Likewise. * ipa-free-lang-data.cc (fld_incomplete_type_of): Use an indefinite article rather than a. --- gcc/tree.cc.jj 2024-04-15 14:25:21.721813546 +0200 +++ gcc/tree.cc 2024-04-15 17:49:25.923935286 +0200 @@ -3689,7 +3689,7 @@ int_byte_position (const_tree field) } /* Return, as a tree node, the number of elements for TYPE (which is an - ARRAY_TYPE) minus one.
