| | | | llvm-svn: 22315
* tracking the instructions causing loads and stores provides more information ↵Andrew Lenharth2005-06-291-4/+3

* fix most regressionsAndrew Lenharth2005-06-291-1/+2
| | | | llvm-svn: 22307
* support more relocations for stores alsoAndrew Lenharth2005-06-292-1/+36
| | | | llvm-svn: 22306
* Get rid of all symbolic loads. I now do gernate all relocations sequencesAndrew Lenharth2005-06-293-230/+76
| | | | | | | rather than relying on the assembler. Only a few more pseudo instructions left. Also merge load code paths. llvm-svn: 22305
* So, it turns out I forgot that one valid way of restoring GP after a callAndrew Lenharth2005-06-271-3/+3
| | | | | | | is to use RA, which assumes the called function uses RA for the register holding the return address when it issues a ret. llvm-svn: 22301
* get rid of another pseudo opAndrew Lenharth2005-06-272-3/+4
| | | | llvm-svn: 22299
* generate address of constant pool entriesAndrew Lenharth2005-06-272-5/+10

| | | | llvm-svn: 22297
* Reduce use of pseudo opsAndrew Lenharth2005-06-272-8/+41
| | | | | | | Namely, output the rellocation flags explicitly when loading constants. Added benifit: save a load when loading from the constant pool. llvm-svn: 22296
* missed a loadAndrew Lenharth2005-06-271-3/+7
| | | | llvm-svn: 22295

* who said we had to use the return address in the return address register. ↵Andrew Lenharth2005-06-272-5/+8
| | | | | | Might save a move in many cases llvm-svn: 22293
* depend more on legalize putting constants on the RHSAndrew Lenharth2005-06-261-92/+29
| | | | llvm-svn: 22289
* With setOperationAction(ISD::UINT_TO_FP, MVT::i64, Expand), LegalizeAndrew Lenharth2005-06-261-36/+12
| | | | | | | should be able to handle this case. The code is there, so let's see if it works. llvm-svn: 22288
* Refactor the addPassesToEmitAssembly interface into a addPassesToEmitFileChris Lattner2005-06-252-5/+8
| | | | | | interface. llvm-svn: 22282
* remove a pseudo instruction, make ret always right, and fix vararg chainsAndrew Lenharth2005-06-234-15/+20

| | | | | | | of memory instructions in the assembly, to allow later linking of traces with LLVM Value*s. llvm-svn: 22271
* core changes for varargsAndrew Lenharth2005-06-181-8/+30

| | | | | | information to reconstruct the Value* if it existed llvm-svn: 22195
* hide basic block labels. The utility of these for debuging is long since passedAndrew Lenharth2005-06-061-2/+2
| | | | llvm-svn: 22194

| | | | | | * Remove warning "control reaches end of non-void function" llvm-svn: 22193
* try custom expanders, doesn't seem to expand yet, so disabledAndrew Lenharth2005-05-311-0/+61
| | | | llvm-svn: 22188

* Fix 2005-05-12-Int64ToFPAndrew Lenharth2005-05-261-0/+26
| | | | | | | | | The issue is there is no unsigned -> double conversion, only signed. So I need to test the sign and do a different thing depending on it. Ideally this should be in a different BB, but in the mean time, I use a branch free method. llvm-svn: 22177
* treat TAILCALL nodes identically to CALL nodesChris Lattner2005-05-131-2/+4
| | | | llvm-svn: 21977
* Add an isTailCall flag to LowerCallToChris Lattner2005-05-131-2/+3
| | | | llvm-svn: 21958
* rename the ADJCALLSTACKDOWN/ADJCALLSTACKUP nodes to be CALLSEQ_START/BEGIN.Chris Lattner2005-05-121-5/+5
| | | | llvm-svn: 21915
* Pass in Calling Convention to use into LowerCallToChris Lattner2005-05-121-1/+2
| | | | llvm-svn: 21899
* fix typoAndrew Lenharth2005-05-041-1/+1

* Well, add support for ct* for 21264 only.Andrew Lenharth2005-05-042-5/+11
| | | | | | 21164 is broken until expand works. llvm-svn: 21692
* Implement count leading zeros (ctlz), count trailing zeros (cttz), and countAndrew Lenharth2005-05-032-6/+16
| | | | | | | | | population (ctpop). Generic lowering is implemented, however only promotion is implemented for SelectionDAG at the moment. More coming soon. llvm-svn: 21676
* I was sure I had thought about this and there was a reason it should work.Andrew Lenharth2005-04-301-7/+8
| | | | | | But it is entirely possible I am just crazy. llvm-svn: 21640
* Eliminate some random whitespaceChris Lattner2005-04-301-1/+1
| | | | llvm-svn: 21637
* This target doesn't support the FSIN/FCOS/FSQRT nodes yetChris Lattner2005-04-301-1/+9
| | | | llvm-svn: 21633
* Implement Value* tracking for loads and stores in the selection DAG. This ↵Andrew Lenharth2005-04-271-3/+3
| | | | | | | | enables one to use alias analysis in the backends. (TRUNK)Stores and (EXT|ZEXT|SEXT)Loads have an extra SDOperand which is a SrcValueSDNode which contains the Value*. Note that if the operation is introduced by the backend, it will still have the operand, but the value* will be null. llvm-svn: 21599
