Chris Lattner 1ea6d207ce Convert to the new MachineFunctionInfo interface
llvm-svn: 15904
2004-08-18 18:13:37 +00:00
Brian Gaeke b8183ff647 The SparcV9 target no longer uses any pseudoinstructions (SETSW, SETUW,
SETX) or M_PSEUDO_FLAG.

llvm-svn: 15901
2004-08-18 17:44:16 +00:00
Brian Gaeke 2fbe85b1f3 The Create*Const methods don't need to pass around a TargetMachine reference.
Other minor cleanups.

llvm-svn: 15900
2004-08-18 17:44:15 +00:00
Brian Gaeke c03556f67e Doxygenify some comments.
Clean up cpReg2MemMI and cpMem2RegMI, and doxygenify comments.
Get rid of their uses of SETSW, which is a pseudoinstruction. We can't
JIT-compile pseudoinstructions at the moment. This was blowing up 252.eon/jit,
which has some HUGE stack frames.
Reduce the uses of constantFitsInImmedField().
Consolidate some assertions.

llvm-svn: 15473
2004-08-04 07:29:53 +00:00

the SparcV9 BURG instruction selector.  Eww!

llvm-svn: 15472
2004-08-04 07:29:40 +00:00
Brian Gaeke 908df3299f Add a Doxygen comment, and inline the constructor (which is now almost empty).

2004-08-04 07:29:16 +00:00
Brian Gaeke b3e3c539a4 Add a new file containing just TmpInstruction and its implementation.
Many other pieces of the SparcV9 backend want to use TmpInstruction, but
don't need any other instruction selector baggage.

llvm-svn: 15469
2004-08-04 07:29:04 +00:00
Brian Gaeke 61dd48425f All the SparcV9 BURG instruction selector pieces have been collected into the
new file SparcV9BurgISel.cpp, with exposed interfaces in SparcV9BurgISel.h.

Use LiveRange's iterator types and operations instead of ValueSet's.

llvm-svn: 15321
2004-07-29 06:43:08 +00:00
Brian Gaeke 3073fe3cee Don't derive from ValueSet to implement class LiveRange; instead, use a
SetVector<Value *> data member.

Brian Gaeke f4c1d1ee34 TargetInstrInfo::getNOPOpCode() has been replaced by a reference to V9::NOP.
llvm-svn: 15279
2004-07-27 17:43:24 +00:00
Brian Gaeke 64f51df06d Convert many of the virtual TargetInstrInfo methods used as helper
functions in SparcV9InstrSelection and SparcV9PreSelection into regular
old global functions.  As it happens, none of them really have anything
to do with TargetInstrInfo.

llvm-svn: 15278
2004-07-27 17:43:23 +00:00
Brian Gaeke b788626dc8 As it happens, none of these TargetInstrInfo methods which are only
used in the SparcV9 backend really have anything to do with
TargetInstrInfo, so we're converting them into regular old global
functions and moving their declarations to SparcV9InstrSelectionSupport.h.
(They're mostly used as helper functions for SparcV9InstrSelection.)

Brian Gaeke ae6fb8ae5c Make the most commonly preselected instructions add to the names of the

Brian Gaeke f70544c583 Add MRegisterInfo subclass for the SparcV9 target (containing only stub
functions for now). This automatically turns on the printing of machine
registers using their own real names, instead of goofy things like %mreg(42),
and allows us to migrate code incrementally to the new interface as we see fit.

The register file description it uses is hand-written, so that the register
numbers will match the ones that the SparcV9 target already uses.
Perhaps someday we'll tablegen it.

Move lowerselect pass to come after preselection.  Move machine

Make the sequence of passes in addPassesToJITCompile look more like
the sequence of passes in addPassesToEmitAssembly, including support

Divorce state-saving from the doFinalization method; for some reason it's not
getting called when I want it to, at Reoptimizer time. Put the guts in
PhyRegAlloc::finishSavingState(). Put an abort() in it so that I can be really
really sure that it's getting called.

Brian Gaeke 427cec1395 TargetCacheInfo has been removed; its only uses were to propagate a constant
(16) into certain areas of the SPARC V9 back-end. I'm fairly sure the US IIIi's

the interest of not breaking things any more than they already are, I'm going
to leave the constant alone.
