* [SystemZ] Add FI[EDX]BRARichard Sandiford2013-08-211-1/+2
| | | | | | | | These are extensions of the existing FI[EDX]BR instructions, but use a spare bit to suppress inexact conditions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188894 91177308-0d34-0410-b5e6-96231b3b80d8
* [SystemZ] Add RISBLG and RISBHG instruction definitionsRichard Sandiford2013-07-311-1/+1
| | | | | | | The next patch will make use of RISBLG for codegen. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187490 91177308-0d34-0410-b5e6-96231b3b80d8
* [SystemZ] Add STOC and STOCGRichard Sandiford2013-07-251-1/+1
| | | | | | | | | These instructions are allowed to trap even if the condition is false, so for now they are only used for "*ptr = (cond ? x : *ptr)"-style constructs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187111 91177308-0d34-0410-b5e6-96231b3b80d8
* [SystemZ] Start adding z196 and zEC12 supportRichard Sandiford2013-07-191-1/+3
| | | | | | | | | | | | | This first step just adds definitions for SLLK, SRLK and SRAK. The next patch will actually make use of them during codegen. insn-bad.s tests that some form of error is reported when using these instructions on z10. More work is needed to get the "instruction requires: distinct-ops" that we'd ideally like, so I've stubbed that part out for now. I'll come back and make it mandatory once the necessary changes are in. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186680 91177308-0d34-0410-b5e6-96231b3b80d8
* [SystemZ] Add back endUlrich Weigand2013-05-061-0/+56
| | | | | | | | | | | | | | | | 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! Patch by Richard Sandiford. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181203 91177308-0d34-0410-b5e6-96231b3b80d8

* Move TargetRegistry and TargetSelect from Target to Support where they belong.Evan Cheng2011-08-241-1/+1
| | | | | | | These are strictly utilities for registering targets and components. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138450 91177308-0d34-0410-b5e6-96231b3b80d8

* - Eliminate MCCodeEmitter's dependency on TargetMachine. It now uses MCInstrInfoEvan Cheng2011-07-111-1/+1
| | | | | | | | | | | | | and MCSubtargetInfo. - Added methods to update subtarget features (used when targets automatically detect subtarget features or switch modes). - Teach X86Subtarget to update MCSubtargetInfo features bits since the MCSubtargetInfo layer can be shared with other modules. - These fixes .code 16 / .code 32 support since mode switch is updated in MCSubtargetInfo so MC code emitter can do the right thing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134884 91177308-0d34-0410-b5e6-96231b3b80d8
* Change createAsmParser to take a MCSubtargetInfo instead of triple,Evan Cheng2011-07-091-0/+13
| | | | | | | | | | CPU, and feature string. Parsing some asm directives can change subtarget state (e.g. .code 16) and it must be reflected in other modules (e.g. MCCodeEmitter). That is, the MCSubtargetInfo instance must be shared. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134795 91177308-0d34-0410-b5e6-96231b3b80d8
* Eliminate asm parser's dependency on TargetMachine:Evan Cheng2011-07-081-1/+2
| | | | | | | | | | | - Each target asm parser now creates its own MCSubtatgetInfo (if needed). - Changed AssemblerPredicate to take subtarget features which tablegen uses to generate asm matcher subtarget feature queries. e.g. "ModeThumb,FeatureThumb2" is translated to "(Bits & ModeThumb) != 0 && (Bits & FeatureThumb2) != 0". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134678 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix the ridiculous SubtargetFeatures API where it implicitly expects CPU name toEvan Cheng2011-06-301-2/+5
| | | | | | | | | | | be the first encoded as the first feature. It then uses the CPU name to look up features / scheduling itineray even though clients know full well the CPU name being used to query these properties. The fix is to just have the clients explictly pass the CPU name! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134127 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | Module*. Also, dropped uses of TargetMachine where unnecessary. The only target which still takes a TargetMachine& is Mips, I would appreciate it if someone would normalize this to match other targets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77918 91177308-0d34-0410-b5e6-96231b3b80d8
