[SystemZ] Add patterns to load a constant into a high word (IIHF) Similar to low words, we can use the shorter LLIHL and LLIHH if it turns out that the other half of the GR64 isn't live. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191750 91177308-0d34-0410-b5e6-96231b3b80d8

[SystemZ] Add GRH32 for the high word of a GR64 The only thing this does on its own is make the definitions of RISB[HL]G a bit more precise. Those instructions are only used by the MC layer at the moment, so no behavioral change is intended. The class is needed by later patches though. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191660 91177308-0d34-0410-b5e6-96231b3b80d8

[SystemZ] Define the GR64 low-word logic instructions as pseudo aliases. Another patch to avoid duplication of encoding information. Things like NILF, NILL and NILH are used as both 32-bit and 64-bit instructions. Here the 64-bit versions are defined as aliases of the 32-bit ones. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191369 91177308-0d34-0410-b5e6-96231b3b80d8

[SystemZ] Add instruction-shortening pass When loading immediates into a GR32, the port prefered LHI, followed by LLILH or LLILL, followed by IILF. LHI and IILF are natural 32-bit operations, but LLILH and LLILL also clear the upper 32 bits of the register. This was represented as taking a 32-bit subreg of a 64-bit assignment. Using subregs for something as simple as a move immediate was probably a bad idea. Also, I have patches to add support for the high-word facility, and we don't want something like LLILH and LLILL to stop the high word of the same GPR from being used. This patch therefore uses LHI and IILF to begin with and adds a late machine-specific pass to use LLILH and LLILL if the other half of the register is not live. The high-word patches extend this behavior to IIHF, LLIHL and LLIHH. No behavioral change intended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191363 91177308-0d34-0410-b5e6-96231b3b80d8

Generate compact unwind encoding from CFI directives. We used to generate the compact unwind encoding from the machine instructions. However, this had the problem that if the user used `-save-temps' or compiled their hand-written `.s' file (with CFI directives), we wouldn't generate the compact unwind encoding. Move the algorithm that generates the compact unwind encoding into the MCAsmBackend. This way we can generate the encoding whether the code is from a `.ll' or `.s' file. <rdar://problem/13623355> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190290 91177308-0d34-0410-b5e6-96231b3b80d8

[SystemZ] Match operands to fields by name rather than by order The SystemZ port currently relies on the order of the instruction operands matching the order of the instruction field lists. This isn't desirable for disassembly, where the two are matched only by name. E.g. the R1 and R2 fields of an RR instruction should have corresponding R1 and R2 operands. The main complication is that addresses are compound operands, and as far as I know there is no mechanism to allow individual suboperands to be selected by name in "let Inst{...} = ..." assignments. Luckily it doesn't really matter though. The SystemZ instruction encoding groups all address fields together in a predictable order, so it's just as valid to see the entire compound address operand as a single field. That's the approach taken in this patch. Matching by name in turn means that the operands to COPY SIGN and CONVERT TO FIXED instructions can be given in natural order. (It was easier to do this at the same time as the rename, since otherwise the intermediate step was too confusing.) No functional change intended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181771 91177308-0d34-0410-b5e6-96231b3b80d8

[SystemZ] Add back end This adds the actual lib/Target/SystemZ target files necessary to implement the SystemZ target. Note that at this point, the target cannot yet be built since the configure bits are missing. Those will be provided shortly by a follow-on patch. This version of the patch incorporates feedback from reviews by Chris Lattner and Anton Korobeynikov. Thanks to all reviewers!
