[mips] Add tests for the 'ret', 'call', and 'indirectbr' LLVM IR instruction. Summary: The tests in this directory are intended to test a single IR instruction with as few dependencies on other instructions as possible. The aim is to be very confident that each LLVM-IR instruction is implemented correctly and with the optimal sequence of instructions, as well as to make it easy to tell what is tested, and make it easier to bring up new ISA revisions in the future. This gives us a good foundation on which to test bigger things. These particular tests will allow testing that MIPS32r6/MIPS64r6 generate the correct return instruction for returns, calls, and indirect branches. This will be a bit tricky since the assembly text is identical but the instruction is actually different. On MIPS32r6/MIPS64r6 'jr $rs' has been removed in favour of the equivalent 'jalr $zero, $rs'. 'jr $rs' remains as an alias for 'jalr $zero, $rs'. Differential Revision: http://reviews.llvm.org/D4266 llvm-svn: 212345

[mips] MIPSR6 Compact jump support This patch adds support for compact jumps similiar to the previous compact branch support for MIPSR6. Unlike compact branches, compact jumps do not have a forbidden slot. As MipsInstrInfo::getEquivalentCompactForm can determine the correct expansion for jumps and branches for both microMIPS and MIPSR6, remove the unnecessary distinction in the delay slot filler.

[mips] MIPSR6 Compact jump support This patch adds support for compact jumps similiar to the previous compact branch support for MIPSR6. Unlike compact branches, compact jumps do not have a forbidden slot. As MipsInstrInfo::getEquivalentCompactForm can determine the correct expansion for jumps and branches for both microMIPS and MIPSR6, remove the unnecessary distinction in the delay slot filler.

[mips] Add tests for the 'ret', 'call', and 'indirectbr' LLVM IR instruction. Summary: The tests in this directory are intended to test a single IR instruction with as few dependencies on other instructions as possible. The aim is to be very confident that each LLVM-IR instruction is implemented correctly and with the optimal sequence of instructions, as well as to make it easy to tell what is tested, and make it easier to bring up new ISA revisions in the future. This gives us a good foundation on which to test bigger things. These particular tests will allow testing that MIPS32r6/MIPS64r6 generate the correct return instruction for returns, calls, and indirect branches. This will be a bit tricky since the assembly text is identical but the instruction is actually different. On MIPS32r6/MIPS64r6 'jr $rs' has been removed in favour of the equivalent 'jalr $zero, $rs'. 'jr $rs' remains as an alias for 'jalr $zero, $rs'. Differential Revision: http://reviews.llvm.org/D4266 llvm-svn: 212345

Use TargetRegisterInfo for printing MachineOperand register comments Several places in AsmPrinter.cpp print comments describing MachineOperand registers using MCRegisterInfo, which uses MCOperand-oriented names. This doesn't work for targets that use virtual registers exclusively, as WebAssembly does, since virtual registers are represented and printed differently. This patch preserves what seems to be the spirit of r229978, avoiding the use of TM.getSubtargetImpl(), while still using MachineOperand-oriented printing for MachineOperands.
