For PR1028: Ensure the CBE generates calls to GCC builtins for stack_save and stack_restore when it encounters the corresponding intrinsics. Patch by Gordon Henriksen. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33312 91177308-0d34-0410-b5e6-96231b3b80d8 2007-01-17 23:20:43 +00:00			`; RUN: llvm-as < %s \| llc -march=c \| grep __builtin_stack_save`

For PR761: Remove "target endian/pointersize" or add "target datalayout" to make the test parse properly or set the datalayout because defaults changes. For PR645: Make global names use the @ prefix. For llvm-upgrade changes: Fix test cases or completely remove use of llvm-upgrade for test cases that cannot survive the new renaming or upgrade capabilities. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33533 91177308-0d34-0410-b5e6-96231b3b80d8 2007-01-26 08:25:06 +00:00			`declare i8* @llvm.stacksave()`
