[mips][mips64r6] [ls][dw][lr] are not available in MIPS32r6/MIPS64r6 Summary: Instead the system is required to provide some means of handling unaligned load/store without special instructions. Options include full hardware support, full trap-and-emulate, and hybrids such as hardware support within a cache line and trap-and-emulate for multi-line accesses. MipsSETargetLowering::allowsUnalignedMemoryAccesses() has been configured to assume that unaligned accesses are 'fast' on the basis that I expect few hardware implementations will opt for pure-software handling of unaligned accesses. The ones that do handle it purely in software can override this. mips64-load-store-left-right.ll has been merged into load-store-left-right.ll The stricter testing revealed a Bits!=Bytes bug in passByValArg(). This has been fixed and the variables renamed to clarify the units they hold.

[mips][mips64r6] b(ge|lt)zal are not available on MIPS32r6/MIPS64r6 and bal is a normal instruction Summary: b(ge|lt)zal have been removed in MIPS32r6/MIPS64r6. However, bal (an alias for 'bgezal $zero, $offset') still remains with the same encoding it had prior to MIPS32r6/MIPS64r6. Updated the MipsNaCLELFStreamer, and MipsLongBranch to correctly handle the MIPS32r6/MIPS64r6 BAL instruction in addition to the existing BAL_BR pseudo. No changes were required to the CodeGen test that looks for BAL (test/CodeGen/Mips/longbranch.ll) since the new instruction has the same syntax.

[mips][mips64r6] Replace m[tf]hi, m[tf]lo, mult, multu, dmult, dmultu, div, ddiv, divu, ddivu for MIPS32r6/MIPS64. Summary: The accumulator-based (HI/LO) multiplies and divides from earlier ISA's have been removed and replaced with GPR-based equivalents. For example: div $1, $2 mflo $3 is now: div $3, $1, $2 This patch disables the accumulator-based multiplies and divides for MIPS32r6/MIPS64r6 and uses the GPR-based equivalents instead. Renamed expandPseudoDiv to insertDivByZeroTrap to better describe the behaviour of the function. MipsDelaySlotFiller now invalidates the liveness information when moving instructions to the delay slot. Without this, divrem.ll will abort since %GP ends up used before it is defined.
