This required fixing the 2-addr pass to handle tied subregisters. It isn't clear what combinations of subregisters can legally be tied, but the simple case of truncated source operands is now safely handled: %vreg11<def> = COPY %vreg1:sub_32bit; GR32:%vreg11 GR64:%vreg1 %vreg12<def> = COPY %vreg2:sub_32bit; GR32:%vreg12 GR64:%vreg2 %vreg13<def,tied1> = ADD32rr %vreg11<tied0>, %vreg12<kill>, %EFLAGS<imp-def> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@197414 91177308-0d34-0410-b5e6-96231b3b80d8

* [AArch64]Fix the pattern match failure for v1i8/v1i16/v1i32 types.Hao Liu2013-12-16
| | | | | | | | | | | Currently we have such types as legal vector types. The DAG combiner may generate some DAG nodes having such types but we don't have patterns to match them. E.g. a load i32 and a bitcast i32 to v1i32 will be combined into a load v1i32: bitcast (load i32) to v1i32 -> load v1i32. So this patch fixes such problems for load/dup instructions. If v1i8/v1i16/v1i32 are not legal any more, the code in this patch can be deleted. So I also add some FIXME. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@197361 91177308-0d34-0410-b5e6-96231b3b80d8

* [Stackmap] Liveness Analysis PassJuergen Ributzka2013-12-14
| | | | | | | | | | | | | | | | | | | | This optional register liveness analysis pass can be enabled with either -enable-stackmap-liveness, -enable-patchpoint-liveness, or both. The pass traverses each basic block in a machine function. For each basic block the instructions are processed in reversed order and if a patchpoint or stackmap instruction is encountered the current live-out register set is encoded as a register mask and attached to the instruction. Later on during stackmap generation the live-out register mask is processed and also emitted as part of the stackmap. This information is optional and intended for optimization purposes only. This will enable a client of the stackmap to reason about the registers it can use and which registers need to be preserved.

| | | | | | | | | | | | | | | | | | | | | | | MachineBlockFrequencyInfo methods. This is slightly more interesting than the previous batch of changes. Specifically: 1. We refactor getSpillWeight to take a MachineBlockFrequencyInfo (MBFI) object. This enables us to completely encapsulate the actual manner we use the MachineBlockFrequencyInfo to get our spill weights. This yields cleaner code since one does not need to fetch the actual block frequency before getting the spill weight if all one wants it the spill weight. It also gives us access to entry frequency which we need for our computation. 2. Instead of having getSpillWeight take a MachineBasicBlock (as one might think) to look up the block frequency via the MBFI object, we instead take in a MachineInstr object. The reason for this is that the method is supposed to return the spill weight for an instruction according to the comments around the function. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@197296 91177308-0d34-0410-b5e6-96231b3b80d8
