Also, while noone's looking, add support for constant expressions.  Wait,
I said not to look!

llvm-svn: 14508

Allow copying of float registers.

llvm-svn: 14445

llvm-svn: 14444

If we see an "unknown operand", abort so it's easier to fix it.

llvm-svn: 14441

Support cast of ints (and narrower) to float and double.
Support cast double to double (using load and store).
Abort if we see a CallInst or SetCondInst with long/fp args, instead
of producing bad code.
Support add, sub, mul, div of float and double.

llvm-svn: 14440

* Wrap long line to 80 cols

llvm-svn: 14382

llvm-svn: 14372

(It's not yet clear how to copy doubles from register to register.)

llvm-svn: 14371

llvm-svn: 14366

Compactify the code that emits copies of constant ints into registers.

llvm-svn: 14365

llvm-svn: 14364

Fix bug in emitGEPOperation where we weren't passing MBB, IP to getReg.
(hey, wouldn't a constant expression lowering pass be cool? huh huhuhuh)
Fix bug in emitGEPOperation where we might try to OR a constant into a
register which was too big to fit in the immediate field.
Support and, or, xor of longs.

llvm-svn: 14363

variant worth worrying about; the fp ones have two.

llvm-svn: 14362

variant worth worrying about; the fp ones have two.
Add fp stores.

llvm-svn: 14361

variant worth worrying about; the fp ones have two.
Stub out the case analysis of int-to-fp casts (no code yet).
I think the number of operands passed to BuildMI for loads was wrong.
Support load and store of float and double.

llvm-svn: 14360

representational consistency, we want to address the halves of each 64-bit value
separately.

llvm-svn: 14356

using the local & in regs first because they are not clobbered by calls.

llvm-svn: 14228

llvm-svn: 14227

Replace it with a working class for FP instrs.

llvm-svn: 14226

Add some FP moves.

llvm-svn: 14225

Use this for printing the jmpl indirect-call instruction.

llvm-svn: 14224

Support indirect calls.
Support returning a float value.

llvm-svn: 14223

llvm-svn: 14217

Support copying floating-point constants to registers.
Add assertion to visitCallInst to abort if we hit a NULL calledFunction, for now.

llvm-svn: 14216

Make copyRegToReg return 1 instead of -1.
Edit a comment in emitPrologue().

llvm-svn: 14211

Add a FIXME about the (currently unused) JMPL instructions.

llvm-svn: 14210

llvm-svn: 14209

modifications for 1 LLVM BB --> many MBBs).
Fix store operand order: make it always be Base, Offset, SrcReg (think
"[ Base + Offset ] = SrcReg").
Rewrite visitBranchInst() to be even dumber (but working) -- give up on
the branch fallthrough trick, for the time being.
Make visitSetCondInst() work.

llvm-svn: 14208

llvm-svn: 14207

Abort if we see a PCRelativeDisp MachineOperand, to be safe. This matches
the X86 backend.
