From e6d4b9d5a311df9e65afba3f92cd203475589397 Mon Sep 17 00:00:00 2001 From: darylm503 Date: Wed, 15 Jul 2009 22:34:41 +0000 Subject: [PATCH] Clean up PERF macro usage. The macros were being used with 0 as the first parameter. This parameter is actually a void*. All of these instances were corrected to use NULL as the first parameter. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@8955 6f19259b-4bc3-4df7-8a09-765794883524 --- MdeModulePkg/Core/Dxe/DxeMain/DxeMain.c | 1614 +++++++++++------------ 1 file changed, 807 insertions(+), 807 deletions(-) diff --git a/MdeModulePkg/Core/Dxe/DxeMain/DxeMain.c b/MdeModulePkg/Core/Dxe/DxeMain/DxeMain.c index 6e535b5d93..777e1db65a 100644 --- a/MdeModulePkg/Core/Dxe/DxeMain/DxeMain.c +++ b/MdeModulePkg/Core/Dxe/DxeMain/DxeMain.c @@ -1,807 +1,807 @@ -/** @file - DXE Core Main Entry Point - -Copyright (c) 2006 - 2008, Intel Corporation.
