[mips][mips64r6] c.cond.fmt, mov[fntz], and mov[fntz].[ds] are not available on MIPS32r6/MIPS64r6 Summary: c.cond.fmt has been replaced by cmp.cond.fmt. Where c.cond.fmt wrote to dedicated condition registers, cmp.cond.fmt writes 1 or 0 to normal FGR's (like the GPR comparisons). mov[fntz] have been replaced by seleqz and selnez. These instructions conditionally zero a register based on a bool in a GPR. The results can then be or'd together to act as a select without, for example, requiring a third register read port. mov[fntz].[ds] have been replaced with sel.[ds] MIPS64r6 currently generates unnecessary sign-extensions for most selects. This is because the result of a SETCC is currently an i32. Bits 32-63 are undefined in i32 and the behaviour of seleqz/selnez would otherwise depend on undefined bits. Later, we will fix this by making the result of SETCC an i64 on MIPS64 targets.

This patch tackles the problem of parsing Mips register names in the standalone assembler llvm-mc. Registers such as $A1 can represent either a 32 or 64 bit register based on the instruction using it. In addition, based on the abi, $T0 can represent different 32 bit registers. The problem is resolved by the Mips specific AsmParser td definitions changing to work together. Many cases of RegisterClass parameters are now RegisterOperand.

[mips][mips64r6] Use JALR for returns instead of JR (which is not available on MIPS32r6/MIPS64r6) Summary: RET, and RET_MM have been replaced by a pseudo named PseudoReturn. In addition a version with a 64-bit GPR named PseudoReturn64 has been added. Instruction selection for a return matches RetRA, which is expanded post register allocation to PseudoReturn/PseudoReturn64. During MipsAsmPrinter, this PseudoReturn/PseudoReturn64 are emitted as: - (JALR64 $zero, $rs) on MIPS64r6 - (JALR $zero, $rs) on MIPS32r6 - (JR_MM $rs) on microMIPS - (JR $rs) otherwise On MIPS32r6/MIPS64r6, 'jr $rs' is an alias for 'jalr $zero, $rs'. To aid development and review (specifically, to ensure all cases of jr are updated), these aliases are temporarily named 'r6.jr' instead of 'jr'. A follow up patch will change them back to the correct mnemonic. Added (JALR $zero, $rs) to MipsNaClELFStreamer's definition of an indirect jump, and removed it from its definition of a call. Note: I haven't accounted for MIPS64 in MipsNaClELFStreamer since it's doesn't appear to account for any MIPS64-specifics. The return instruction created as part of eh_return expansion is now expanded using expandRetRA() so we use the right return instruction on MIPS32r6/MIPS64r6 ('jalr $zero, $rs'). Also, fixed a misuse of isABI_N64() to detect 64-bit wide registers in expandEhReturn().

[mips] Promote i32 arguments to i64 for the N32/N64 ABI and fix <64-bit structs... Summary: ... and after all that refactoring, it's possible to distinguish softfloat floating point values from integers so this patch no longer breaks softfloat to do it. Remove direct handling of i32's in the N32/N64 ABI by promoting them to i64. This more closely reflects the ABI documentation and also fixes problems with stack arguments on big-endian targets. We now rely on signext/zeroext annotations (already generated by clang) and the Assert[SZ]ext nodes to avoid the introduction of unnecessary sign/zero extends. It was not possible to convert three tests to use signext/zeroext. These tests are bswap.ll, ctlz-v.ll, ctlz-v.ll. It's not possible to put signext on a vector type so we just accept the sign extends here for now. These tests don't pass the vectors the same way clang does (clang puts multiple elements in the same argument, these map 1 element to 1 argument) so we don't need to worry too much about it. With this patch, all known N32/N64 bugs should be fixed and we now pass the first 10,000 tests generated by ABITest.py.

[mips] Split Instruction.Predicates into smaller lists and re-join them with !listconcat Summary: The overall idea is to chop the Predicates list into subsets that are usually overridden independently. This allows subclasses to partially override the predicates of their superclasses without having to re-add all the existing predicates. This patch starts the process by moving HasStdEnc into a new EncodingPredicates list and almost everything else into AdditionalPredicates. It has revealed a couple likely bugs where 'let Predicates' has removed the HasStdEnc predicate. No functional change (confirmed by diffing tablegen-erated files).

This is a resubmittal. For some reason it broke the bots yesterday but I cannot reproduce the problem and have scrubed my sources and even tested with llvm-lit -v --vg. Removal of redundant code and formatting fixes. Contributers: Jack Carter/Vladimir Medic llvm-svn: 172842

Expose move to/from coprocessor instructions in MIPS64 mode. Note: [D]M{T,F}CP2 is just a recommended encoding. Vendors often provide a custom CP2 that interprets instructions differently and may wish to add their own instructions that use this opcode. We should ensure that this is easy to do. I will probably add a 'has custom CP{0-3}' subtarget flag to make this easy: We want to avoid the GCC situation where every MIPS vendor makes a custom fork that breaks every other MIPS CPU and so can't be merged upstream. llvm-svn: 165711
