Nick Lewycky 50f02cb21b Move global variables in TargetMachine into new TargetOptions class. As an API
change, now you need a TargetOptions object to create a TargetMachine. Clang
patch to follow.

One small functionality change in PTX. PTX had commented out the machine
verifier parts in their copy of printAndVerify. That now calls the version in
LLVMTargetMachine. Users of PTX who need verification disabled should rely on
not passing the command-line flag to enable it.

Evan Cheng ecb2908bf9 Sink codegen optimization level into MCCodeGenInfo along side relocation model
and code model. This eliminates the need to pass OptLevel flag all over the
place and makes it possible for any codegen pass to use this information.

Bruno Cardoso Lopes 483c269a33 One more patch towards JIT support for Mips.
- Add TSFlags for the instruction formats. The idea here is to use
  as much encoding as possible from getBinaryCodeForInstr, and having
  TSFLags formats for that would make it easier to encode most part
  of the instructions (since Mips encodings are pretty straightforward)
- Improve the mips mechanism for compilation callback
- Add Mips specific code for invalidating the instruction cache
- Next patch will address wrong tablegen encoding

Commit msg added by my own but the patch is from Sasa Stankovic.

Bruno Cardoso Lopes d1d9c78650 Added the infrastructute necessary for MIPS JIT support. Patch by Vladimir
Stefanovic. I removed the part that actually emits the instructions cause
I want that to get in better shape first and in incremental steps. This
also makes it easier to review the upcoming parts.

Evan Cheng efd9b4240f - Move CodeModel from a TargetMachine global option to MCCodeGenInfo.
- Introduce JITDefault code model. This tells targets to set different default
  code model for JIT. This eliminates the ugly hack in TargetMachine where
  code model is changed after construction.

Evan Cheng 2129f59637 Introduce MCCodeGenInfo, which keeps information that can affect codegen
(including compilation, assembly). Move relocation model Reloc::Model from
TargetMachine to MCCodeGenInfo so it's accessible even without TargetMachine.

Evan Cheng fe6e405e8c Fix the ridiculous SubtargetFeatures API where it implicitly expects CPU name to
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!

Dan Gohman bb919dfb6b Implement a bunch more TargetSelectionDAGInfo infrastructure.
Move EmitTargetCodeForMemcpy, EmitTargetCodeForMemset, and
EmitTargetCodeForMemmove out of TargetLowering and into
SelectionDAGInfo to exercise this.

llvm-svn: 103481
2010-05-11 17:31:57 +00:00
Dan Gohman 21cea8ac2e Use const qualifiers with TargetLowering. This eliminates several
const_casts, and it reinforces the design of the Target classes being
immutable.

SelectionDAGISel::IsLegalToFold is now a static member function, because
PIC16 uses it in an unconventional way. There is more room for API
cleanup here.

And PIC16's AsmPrinter no longer uses TargetLowering.

Chris Lattner 9a6cf91261 Change TargetAsmInfo to be constructed via TargetRegistry from a Target+Triple
pair instead of from a virtual method on TargetMachine.  This cuts the final
ties of TargetAsmInfo to TargetMachine, meaning that MC can now use 
TargetAsmInfo.

Eli Friedman 57c11da8df Remove -disable-mips-abicall and -enable-mips-absolute-call command-line
options, which don't appear to be useful.  -enable-mips-absolute-call is
completely unused (and unless I'm mistaken, is supposed to have the 
same effect that -relocation-model=dynamic-no-pic should have), 
and -disable-mips-abicall appears to be effectively a 
synonym for -relocation-model=static. Adjust the few users of hasABICall
to checks which seem more appropriate.  Update MipsSubtarget, 
MipsTargetMachine, and MipselTargetMachine to synchronize with recent 
changes.

Daniel Dunbar 6db8134e80 Provide TargetMachine implementations with reference to Target they were created
from.
 - This commit is almost entirely propogating the reference through the
   TargetMachine subclasses' constructor calls.

Daniel Dunbar 75c12e1569 Remove unused AsmPrinter OptLevel argument, and propogate.

Bill Wendling 026e5d7667 Instead of passing in an unsigned value for the optimization level, use an enum,
which better identifies what the optimization is doing. And is more flexible for
future uses.

Bill Wendling 084669a1c9 Second attempt:
Massive check in. This changes the "-fast" flag to "-O#" in llc. If you want to
use the old behavior, the flag is -O0. This change allows for finer-grained
control over which optimizations are run at different -O levels.

Most of this work was pretty mechanical. The majority of the fixes came from
verifying that a "fast" variable wasn't used anymore. The JIT still uses a
"Fast" flag. I'll change the JIT with a follow-up patch.

Most of this work was pretty mechanical. The majority of the fixes came from
