From a68f664124592829a3b715388e6cfa43f82900c8 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Jos=C3=A9=20Fonseca?= Date: Tue, 15 Apr 2008 18:11:47 +0900 Subject: [PATCH] gallium: Cache one line worth of debug output on windows. The windbg connection seems synchronous, so this speeds up when printing little text at a time (e.g., tgsi output). --- src/gallium/auxiliary/util/p_debug.c | 13 +++++++++---- 1 file changed, 9 insertions(+), 4 deletions(-) diff --git a/src/gallium/auxiliary/util/p_debug.c b/src/gallium/auxiliary/util/p_debug.c index f9366467cd5..c195f618200 100644 --- a/src/gallium/auxiliary/util/p_debug.c +++ b/src/gallium/auxiliary/util/p_debug.c @@ -59,10 +59,15 @@ void _debug_vprintf(const char *format, va_list ap) #ifdef WIN32 #ifndef WINCE /* EngDebugPrint does not handle float point arguments, so we need to use - * our own vsnprintf implementation */ - char buf[512 + 1]; - util_vsnprintf(buf, sizeof(buf), format, ap); - _EngDebugPrint("%s", buf); + * our own vsnprintf implementation.
