From a8ac3fca6f31ece5f9675434f1ddace6cd912c09 Mon Sep 17 00:00:00 2001 From: "Vikram S. Adve" Date: Thu, 25 Apr 2002 04:48:54 +0000 Subject: [PATCH] Added functions to compute the offset of a given incoming or outgoing argument. These are no longer allocated as they are discovered. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2320 91177308-0d34-0410-b5e6-96231b3b80d8 --- include/llvm/Target/TargetFrameInfo.h | 22 +++++++++++++++------- 1 file changed, 15 insertions(+), 7 deletions(-) diff --git a/include/llvm/Target/TargetFrameInfo.h b/include/llvm/Target/TargetFrameInfo.h index df16c730b22..8f1a0becf87 100644 --- a/include/llvm/Target/TargetFrameInfo.h +++ b/include/llvm/Target/TargetFrameInfo.h @@ -20,6 +20,7 @@ //************************* Forward Declarations **************************/ class MachineCodeForMethod; +class TargetMachine; //*************************** External Classes ****************************/ @@ -45,21 +46,28 @@ public: // These methods compute offsets using the frame contents for a // particular method.
