From 3eb12cb68849b1ac2b86b85b7f31a1d60410c15e Mon Sep 17 00:00:00 2001 From: normal Date: Fri, 1 Jun 2018 21:23:20 +0000 Subject: [PATCH] gc.c: reduce size slightly by making MEMOP_TYPE_MALLOC zero Most (if not all) architectures have instructions for comparing against zero, allowing compilers to generate more compact code. Other MEMOP_TYPE_* enum values are not compared in hot paths, but MEMOP_TYPE_MALLOC is checked in objspace_malloc_increase text data bss dec hex filename 84088 264 3664 88016 157d0 gc-before.o 83784 264 3664 87712 156a0 gc.o git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@63546 b2dd03c8-39d4-4d8f-98ff-823fe69b080e --- gc.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/gc.c b/gc.c index 4ebae169ec..6636130abb 100644 --- a/gc.c +++ b/gc.c @@ -7785,9 +7785,9 @@ objspace_malloc_size(rb_objspace_t *objspace, void *ptr, size_t hint) } enum memop_type { - MEMOP_TYPE_MALLOC = 1, - MEMOP_TYPE_FREE = 2, - MEMOP_TYPE_REALLOC = 3 + MEMOP_TYPE_MALLOC = 0, + MEMOP_TYPE_FREE, + MEMOP_TYPE_REALLOC }; static inline void
