Nate Begeman 3f9c17906f Disable switch lowering for targets based on the selection dag isel,
letting the code generator handle them directly.

Chris Lattner 6f95ab7abb Eliminate IntrinsicLowering from TargetMachine.
Make the CBE and V9 backends create their own, since they're the only ones that use it.

2006-03-23 05:43:16 +00:00
Nate Begeman bb01d4f272 Remove BRTWOWAY*
Make the PPC backend not dependent on BRTWOWAY_CC and make the branch
selector smarter about the code it generates, fixing a case in the
readme.

Evan Cheng 2dd2c652b2 Added getTargetLowering() to TargetMachine. Refactored targets to support this.

Chris Lattner 9c7f50376a Copysign needs to be expanded everywhere. Note that Alpha and IA64 should
implement copysign as a native op if they have it.

2006-03-05 05:08:37 +00:00
Duraid Madina 36a2ee299e distinguish between objects and register names, now we can have stuff
with names like "f84", "in6" etc etc.

this should fix one or two tests

Chris Lattner 62c3484e43 Switch targets over to using SelectionDAG::getCALLSEQ_START to create
CALLSEQ_START nodes.

Duraid Madina 4698e4f5fe fix storing booleans (grawp missed this one)
llvm-svn: 26120
2006-02-11 07:33:17 +00:00
Duraid Madina 0010a92375 now short immediates will get matched (previously constants were all
triggering movl 64bit imm fat instructions)

Evan Cheng d1b82d8db0 Match getTargetNode() changes (now return SDNode* instead of SDOperand).

Nate Begeman 7e7f439f85 Fix some of the stuff in the PPC README file, and clean up legalization
of the SELECT_CC, BR_CC, and BRTWOWAY_CC nodes.

llvm-svn: 25875

2006-01-31 22:23:14 +00:00
Chris Lattner 61c9a8e942 Targets all now request ConstantFP to be legalized into TargetConstantFP.
'fpimm' in .td files is now TargetConstantFP.

Nate Begeman 595ec734fc Implement Promote for VAARG, and allow it to be custom promoted for people
who don't want the default behavior (Alpha).

2006-01-28 00:02:51 +00:00
Nate Begeman 8c47c3a3b1 Remove TLI.LowerReturnTo, and just let targets custom lower ISD::RET for
the same functionality.  This addresses another piece of bug 680.  Next,
on to fixing Alpha VAARG, which I broke last time.

Duraid Madina 0ebb0b1c5c fix stack corruption! Previously, 16-byte whole-FP-register stores were
being treated as needing only 8 bytes (though they were 16 byte aligned.)

This should fix a bunch of tests - anyone have any comments, though?

  - in Target.td , SpillSize and SpillAlignment seem dead - is this what
    Size and Alignment do now?
  - in CodeGenRegisters.h/CodeGenTarget.cpp , DeclaredSpillSize and
    DeclaredSpillAlignment seem dead.
  - there are a bunch of comments here and there that don't clearly
    distinguish between 'size' and 'spillsize' etc. hmm.

Nate Begeman e74795cd70 First part of bug 680:
Remove TLI.LowerVA* and replace it with SDNodes that are lowered the same
way as everything else.

Evan Cheng 1092a02619 Default scheduling preference is SchedulingForLatency.

2006-01-23 06:11:45 +00:00
Duraid Madina cc87402925 fix register corruption! (my god.) r15 is a scratch reg, using that as
a frame pointer is a pretty doofus thing to do. use r5 instead, and
mark it callee-saved, coz that's what it is!

int vs uint

Duraid Madina 266ff6056a use proper (82-bit) spills/fills when spilling FP regs, so that
divides don't get broken. this fixes obsequi, smg2000, and probably
a bunch of other stuff (tm)

llvm-svn: 25383
2006-01-17 01:19:49 +00:00
Duraid Madina e995910e64 fixing divides: FP should now be 100%, and integers are fine too
unless you try to div/mod 0 by anything, in which case you will
get some cute number, and not 0, which is bad.
