For PR950: The long awaited CAST patch. This introduces 12 new instructions into LLVM to replace the cast instruction. Corresponding changes throughout LLVM are provided. This passes llvm-test, llvm/test, and SPEC CPUINT2000 with the exception of 175.vpr which fails only on a slight floating point output difference. llvm-svn: 31931 2006-11-27 02:05:10 +01:00			`; Test some floating point casting cases`
Use the llvm-upgrade program to upgrade llvm assembly. llvm-svn: 32115 2006-12-02 05:23:10 +01:00			`; RUN: llvm-upgrade %s -o - \| llvm-as \| opt -instcombine \| llvm-dis \| notcast`
			`; RUN: llvm-upgrade %s -o - \| llvm-as \| opt -instcombine \| llvm-dis \| \`
This test needs to use egrep. llvm-svn: 36012 2007-04-14 22:02:51 +02:00			`; RUN: egrep {ret i8 \(-1\)\\|\(255\)}`

For PR950: Update the test suite to accommodate the change from signed integer types to signless integer types. The changes were of only a few kinds: 1. Make sure llvm-upgrade is run on the source which does the bulk of the changes automatically. 2. Change things like "grep 'int'" to "grep 'i32'" 3. In several tests bitcasting caused the same name to be reused in the same type plane. These had to be manually fixed. The fix was (generally) to leave the bitcast and provide the instruction with a new name. This should not affect the semantics of the test. In a few cases, the bitcasts were known to be superfluous and irrelevant to the test case so they were removed. 4. One test case uses a bytecode file which needed to be updated to the latest bytecode format. llvm-svn: 32789 2006-12-31 07:02:00 +01:00			`sbyte %test1() {`
