Reapply r143206, with fixes. Disallow physical register lifetimes across calls, and only check for nested dependences on the special call-sequence-resource register. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@143660 91177308-0d34-0410-b5e6-96231b3b80d8 2011-11-03 21:49:52 +00:00			`; RUN: llc -march=mipsel < %s \| FileCheck %s`
Revert r131152, r129796, r129761. This code is currently considered to be unreliable on platforms which require memcpy calls, and it is complicating broader legalize cleanups. It is hoped that these cleanups will make memcpy byval easier to implement in the future. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138977 91177308-0d34-0410-b5e6-96231b3b80d8 2011-09-01 23:07:08 +00:00
Enclose directive .cprestore with .set macro and nomacro to silence assembler warning. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137378 91177308-0d34-0410-b5e6-96231b3b80d8 2011-08-11 22:42:31 +00:00			`; CHECK: .set macro`
