From 373ae97a581a3299d77842ebe7536b984fc2af68 Mon Sep 17 00:00:00 2001 From: Reid Spencer Date: Sun, 4 Jul 2004 11:47:22 +0000 Subject: [PATCH] Implementation of SlotTable went into header file. Note that this header is currently not being used but is retained because it will be the basis for a clean up of the SlotCalculator class. llvm-svn: 14612 --- lib/Bytecode/Writer/SlotTable.cpp | 116 ------------------------------ 1 file changed, 116 deletions(-) delete mode 100644 lib/Bytecode/Writer/SlotTable.cpp diff --git a/lib/Bytecode/Writer/SlotTable.cpp b/lib/Bytecode/Writer/SlotTable.cpp deleted file mode 100644 index 42b0b5adb89..00000000000 --- a/lib/Bytecode/Writer/SlotTable.cpp +++ /dev/null @@ -1,116 +0,0 @@ -//===-- SlotTable.cpp - Abstract data type for slot numbers ---------------===// -// -// The LLVM Compiler Infrastructure -// -// This file was developed by the LLVM research group and is distributed under -// the University of Illinois Open Source License.
