From 9eb4d695c49a85f7f72ad68c3c31affd61fef984 Mon Sep 17 00:00:00 2001 From: Joshua Haberman Date: Fri, 1 Apr 2011 15:40:06 -0700 Subject: First rough version of the JIT. It can successfully parse SpeedMessage1. Preliminary results: 750MB/s on Core2 2.4GHz. This number is 2.5x proto2. This isn't apples-to-apples, because proto2 is parsing to a struct and we are just doing stream parsing, but for apps that are currently using proto2, this is the improvement they would see if they could move to stream-based processing. Unfortunately perf-regression-test.py is broken, and I'm not 100% sure why. It would be nice to fix it first (to ensure that there are no performance regressions for the table-based decoder) but I'm really impatient to get the JIT checked in. --- src/upb_string.c | 1 - 1 file changed, 1 deletion(-) (limited to 'src/upb_string.c') diff --git a/src/upb_string.c b/src/upb_string.c index de633bc..8625f76 100644 --- a/src/upb_string.c +++ b/src/upb_string.c @@ -72,7 +72,6 @@ char *upb_string_getrwbuf(upb_string *str, upb_strlen_t len) { void upb_string_substr(upb_string *str, upb_string *target_str, upb_strlen_t start, upb_strlen_t len) { - if(str->ptr) *(char*)0 = 0; assert(str->ptr == NULL); assert(start + len <= upb_string_len(target_str)); if (target_str->src) { -- cgit v1.2.3
