gcc : ChangeLog fold-const.c ggc-page.c
gcc/cp : ChangeLog init.c
Log message:
* fold-const.c (fold): An equality comparison of a non-weak object
against zero has a known result. Similarly an equality comparison
of the address of two non-weak, unaliased symbols has a known result.
* ggc-page.c (struct page_entry): New field PREV.
(ggc_alloc): Update PREV field appropriately.
(sweep_pages): Likewise.
(ggc_free): Likewise. Use PREV field rather than loop to
improve ggc_free performance.
cp/
* init.c (build_vec_delete_1): Convert 2nd argument to NE_EXPR to
the proper type.
