2011-09-01Revert r131152, r129796, r129761. This code is currently consideredDan Gohman
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
2011-09-01Don't drop alignment info on local common symbols.Benjamin Kramer

2011-09-01Permit remat of partial register defs when it is safe.Jakob Stoklund Olesen
An instruction may define part of a register where the other bits are undefined. In that case, it is safe to rematerialize the instruction. For example: %vreg2:ssub_0<def> = VLDRS <cp#0>, 0, pred:14, pred:%noreg, %vreg2<imp-def> The extra <imp-def> operand indicates that the instruction does not read the other parts of the virtual register, so a remat is safe. This patch simply allows multiple def operands for the virtual register. It is MI->readsVirtualRegister() that determines if we depend on a previous value so remat is impossible. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138953 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-01Revert r138794, "Do not try to rematerialize a value from a partial definition."Jakob Stoklund Olesen
The problem is fixed for all register allocators by r138944, so this patch is no longer necessary. <rdar://problem/10032939> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138945 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-01Prevent remat of partial register redefinitions.Jakob Stoklund Olesen
An instruction that redefines only part of a larger register can never be rematerialized since the virtual register value depends on the old value in other parts of the register. This was fixed for the inline spiller in r138794. This patch fixes the problem for all register allocators, and includes a small test case. <rdar://problem/10032939> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138944 91177308-0d34-0410-b5e6-96231b3b80d8
