This is necessary because the classes are shared between all schedulers. Once this patch series is committed there will be an InstrItinClass for each mnemonic with minimal grouping. This does increase the size of the itinerary tables for each MIPS scheduler but we have a few options for dealing with that later. These options include reducing the number of classes once we see the best way to simplify them, or by extending tablegen to be able to compress the table by eliminating duplicates entries, etc. llvm-svn: 199391

[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c.cond.fmt, mov[fntz], and mov[fntz].[ds] are not available on MIPS32r6/MIPS64r6 Summary: c.cond.fmt has been replaced by cmp.cond.fmt.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 mov[fntz] have been replaced by seleqz and selnez.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.

[mips] Promote the result of SETCC nodes to GPR width. Summary: This patch modifies the existing comparison, branch, conditional-move and select patterns, and adds new ones where needed. Also, the updated SLT{u,i,iu} set of instructions generate a GPR width result. The majority of the code changes in the Mips back-end fix the wrong assumption that the result of SETCC nodes always produce an i32 value. The changes in the common code path account for the fact that in 64-bit MIPS targets, i1 is promoted to i32 instead of i64.

[mips] Support SELECT nodes for targets that don't have conditional-move instructions. Summary: For Mips targets that do not have conditional-move instructions, ie. targets before MIPS32 and MIPS-IV, we have to insert a diamond control-flow pattern in order to support SELECT nodes. In order to do that, we add pseudo-instructions with a custom inserter that emits the necessary control-flow that selects the correct value. With this patch we add complete support for code generation of Mips-II targets based on the LLVM test-suite.

[mips] Support SELECT nodes for targets that don't have conditional-move instructions. Summary: For Mips targets that do not have conditional-move instructions, ie. targets before MIPS32 and MIPS-IV, we have to insert a diamond control-flow pattern in order to support SELECT nodes. In order to do that, we add pseudo-instructions with a custom inserter that emits the necessary control-flow that selects the correct value. With this patch we add complete support for code generation of Mips-II targets based on the LLVM test-suite.
