2010-10-21Major update of the MicroBlaze backend. The new features are:Wesley Peck
1. A delay slot filler that searches for valid instructions to fill the delay slot with. Previously NOPs would always be inserted into delay slots. 2. Support for MC based instruction printer added. 3. Support for MC based machine code generation and ELF file generation. ELF file generation does not yet completely work as much of the ELF support infrastructure is still x86/x86-64 specific. 4. General clean up of the MBlaze backend code. Much of the tablegen code has been cleanup and simplified. Bug Fixes: 1. Removed duplicate periods from subtarget feature descriptions. 2. Many of the instructions had bad machine code information in the tablegen files. Much of this has been fixed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@116986 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-20More accurate estimate / tracking of register pressure.Evan Cheng
- Initial register pressure in the loop should be all the live defs into the loop. Not just those from loop preheader which is often empty. - When an instruction is hoisted, update register pressure from loop preheader to the original BB. - Treat only use of a virtual register as kill since the code is still SSA. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@116956 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-19Shrink MachineOperand from 40 to 32 bytes on 64-bit hosts.Jakob Stoklund Olesen
Pull an unsigned out of the Contents union such that it has the same size as two pointers and no padding. Arrange members such that the Contents union and all pointers can be 8-byte aligned without padding. This speeds up code generation by 0.8% on a 64-bit host. 32-bit hosts should be unaffected. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@116857 91177308-0d34-0410-b5e6-96231b3b80d8
