* [mips][mips64r6] ll, sc, lld, and scd are re-encoded on MIPS32r6/MIPS64r6.Daniel Sanders2014-06-16
| | | | | | | | | | | | | | | | | | | | | Summary: The linked-load, store-conditional operations have been re-encoded such that have a 9-bit offset instead of the 16-bit offset they have prior to MIPS32r6/MIPS64r6. While implementing this, I noticed that the atomic load/store pseudos always emit a sign extension using sll and sra. I have improved this to use seb/seh when they are available (MIPS32r2/MIPS64r2 and above).

* [mips][mips64r6] c.cond.fmt, mov[fntz], and mov[fntz].[ds] are not available ↵Daniel Sanders2014-06-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | on MIPS32r6/MIPS64r6 Summary: c.cond.fmt has been replaced by cmp.cond.fmt.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 mov[fntz] have been replaced by seleqz and selnez.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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Highlights: - Registers are resolved much later (by the render method). Prior to that point, GPR32's/GPR64's are GPR's regardless of register size. Similarly FGR32's/FGR64's/AFGR64's are FGR's regardless of register size or FR mode. Numeric registers can be anything. - All registers are parsed the same way everywhere (even when handling symbol aliasing) - One consequence is that all registers can be specified numerically almost anywhere (e.g. $fccX, $wX). The exception is symbol aliasing but that can be easily resolved. - Removes the need for the hasConsumedDollar hack - Parenthesis and Bracket suffixes are handled generically - Micromips instructions are parsed directly instead of going through the standard encodings first. - rdhwr accepts all 32 registers, and the following instructions that previously xfailed now work: ddiv, ddivu, div, divu, cvt.l.[ds], se[bh], wsbh, floor.w.[ds], c.ngl.d, c.sf.s, dsbh, dshd, madd.s, msub.s, nmadd.s, nmsub.s, swxc1 - Diagnostics involving registers point at the correct character (the $) - There's only one kind of immediate in MipsOperand. LSA immediates are handled by the predicate and renderer. Lowlights: - Hardcoded '$zero' in the div patterns is handled with a hack. MipsOperand::isReg() will return true for a k_RegisterIndex token with Index == 0 and getReg() will return ZERO for this case. Note that it doesn't return ZERO_64 on isGP64() targets. - I haven't cleaned up all of the now-unused functions. Some more of the generic parser could be removed too (integers and relocs for example). - insve.df needed a custom decoder to handle the implicit fourth operand that was needed to make it parse correctly.

Updating LangRef and adding some tests for the implemented architectures. Other archs will have to implement the method in case this builtin has to be compiled for it, since the default behaviour is to bail unimplemented. A Clang patch is required for the builtin to be lowered into the llvm intrinsic.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | BUILD_VECTOR. Most constant BUILD_VECTOR's are matched using ComplexPatterns which cover bitcasted as well as normal vectors. However, it doesn't seem to be possible to match ldi.[bhwd] in a type-agnostic manner (e.g. to support the widest range of immediates, it should be possible to use ldi.b to load v2i64) using TableGen so ldi.[bhwd] is matched using custom code in MipsSEISelDAGToDAG.cpp This made the majority of the constant splat BUILD_VECTOR lowering redundant. The only transformation remaining for constant splats is when an (up-to) 32-bit constant splat is possible but the value does not fit into a 10-bit signed integer. In this case, the BUILD_VECTOR is transformed into a bitcasted BUILD_VECTOR so that fill.[bhw] can be used to splat the vector from a GPR32 register (which is initialized using the usual lui/addui sequence). There are no additional tests since this is a re-implementation of previous functionality. The change is intended to make it easier to implement some of the upcoming instruction selection patches since they can rely on existing support for BUILD_VECTOR's in the DAGCombiner. compare_float.ll changed slightly because a BITCAST is no longer introduced during legalization. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191299 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mips16/mips32 floating point interoperability. This patch fixes returns from mips16 functions so that if the function was in fact called by a mips32 hard float routine, then values that would have been returned in floating point registers are so returned. Mips16 mode has no floating point instructions so there is no way to load values into floating point registers. This is needed when returning float, double, single complex, double complex in the Mips ABI. Helper functions in libc for mips16 are available to do this. For efficiency purposes, these helper functions have a different calling convention from normal Mips calls. Registers v0,v1,a0,a1 are used to pass parameters instead of a0,a1,a2,a3. This is because v0,v1,a0,a1 are the natural registers used to return floating point values in soft float. These values can then be moved to the appropriate floating point registers with no extra cost. The only register that is modified is ra in this call. The helper functions make sure that the return values are in the floating point registers that they would be in if soft float was not in effect (which it is for mips16, though the soft float is implemented using a mips32 library that uses hard float). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181641 91177308-0d34-0410-b5e6-96231b3b80d8
