 2011-02-23 18:52:05 +00:00
Richard Osborne 4995b05f56 Add llvm.xcore.waitevent intrinsic. The effect of this intrinsic is to enable 
events on the thread and wait until a resource is ready to event. The vector
of the resource that is ready is returned.

Eric Christopher 2401271217 Remove isTwoAddress from XCore. 
llvm-svn: 106446
 2010-06-21 18:51:38 +00:00
Chris Lattner b7c48433df fix a type contradition: XCoreISD::RETSP has one argument, not zero. 
llvm-svn: 99760
 2010-03-28 08:47:39 +00:00
Chris Lattner 0433699ef0 set SDNPVariadic on nodes throughout the rest of the targets that 
need them.

Richard Osborne 00fb2ce233 Don't mark call instruction as a barrier. 
llvm-svn: 96983
 2010-02-23 21:08:11 +00:00
Richard Osborne 3a53f4e240 ECALLF, ECALLT shouldn't be marked as barriers. 
llvm-svn: 96964
 2010-02-23 18:29:49 +00:00
Richard Osborne f81db146b4 Mark unconditional branches as barriers. Found using -verify-machineinstrs 
llvm-svn: 96960
 2010-02-23 18:13:38 +00:00
Richard Osborne f578196968 Lower BR_JT on the XCore to a jump into a series of jump instructions. 
llvm-svn: 96942
 2010-02-23 13:25:07 +00:00

llvm-svn: 86851
 2009-11-11 18:11:07 +00:00
Dan Gohman 453d64c9f5 Rename usesCustomDAGSchedInserter to usesCustomInserter, and update a 
bunch of associated comments, because it doesn't have anything to do
with DAGs or scheduling. This is another step in decoupling MachineInstr
emitting from scheduling.

 2009-10-29 18:10:34 +00:00
Richard Osborne 4e13316bf9 Add some peepholes for signed comparisons using ashr X, X, 32. 
llvm-svn: 83549

Richard Osborne 692f6e7f9d Remove xs1b predicate since it is no longer needed to differentiate betweem 
xs1a and xs1b.

llvm-svn: 83383
 2009-10-06 16:17:57 +00:00
Richard Osborne d7b887410d Remove xs1a subtarget. xs1a is a preproduction device used in 
early development boards which is no longer supported in the
XMOS toolchain.

are being properly selected.

Bill Wendling 09f17a8479 Untabification. 
llvm-svn: 72604
 2009-05-30 01:09:53 +00:00
Richard Osborne 4359325ba8 Add pseudo instructions to the XCore for (load|store|load address) of a 
frame index. eliminateFrameIndex will replace these instructions with
(LDWSP|STWSP|LDAWSP) or (LDW|STW|LDAWF) if a frame pointer is in use.

This fixes PR 3324. Previously we used LDWSP, STWSP, LDAWSP before frame
pointer elimination. However since they were marked as implicitly using
SP they could not be rematerialised.
