[mips] Add registers and ALL check prefix to octeon test case. No functional change. Reviewed by D. Sanders llvm-svn: 226574

[MIPS] Add cpu octeon and some instructions The Octeon cpu from Cavium Networks is mips64r2 based and has an extended instruction set. In order to utilize this with LLVM, a new cpu feature "octeon" and a subtarget feature "cnmips" is added. A small set of new instructions (baddu, dmul, pop, dpop, seq, sne) is also added. LLVM generates dmul, pop and dpop instructions with option -mcpu=octeon or -mattr=+cnmips. llvm-svn: 204337

[mips] Add more Octeon cnMips instructions Adds the instructions ext/ext32/cins/cins32. It also changes pop/dpop to accept the two operand version and adds a simple pattern to generate baddu. Tests for the two operand versions (including baddu/dmul/dpop/pop) and the code generation pattern for baddu are included. Reviewed by: Daniel.Sanders@imgtec.com llvm-svn: 205449

[mips] Refine octeon instructions seq/seqi/sne/snei This commit refines the pattern for the octeon seq/seqi/sne/snei instructions. The target register is set to 0 or 1 according to the result of the comparison. In C, this is something like rd = (unsigned long)(rs == rt) This commit adds a zext to bring the result to i64. With this change the instruction is selected for this type of code. (gcc produces the same code for the above C code.) llvm-svn: 225968
