Chris Lattner 8e2ef196ae add support for 128 bit inputs on both x86-64 and x86-32. 
llvm-svn: 57709
 2008-10-17 18:15:05 +00:00
Chris Lattner c7e65f4377 Fix a bug where the x86 backend would reject 64-bit r constraints when 
in 32-bit mode instead of assigning a register pair.  This has nothing to
do with PR2356, but I happened to notice it while working on it.

llvm-svn: 57704
 2008-10-17 17:59:52 +00:00
Dan Gohman 4a87660127 Remove an unused variable. 
llvm-svn: 57621
 2008-10-16 01:47:47 +00:00
Evan Cheng 3b0f5e4d61 - Add target lowering hooks that specify which setcc conditions are illegal, 
i.e. conditions that cannot be checked with a single instruction. For example,
SETONE and SETUEQ on x86.
- Teach legalizer to implement *illegal* setcc as a and / or of a number of
legal setcc nodes. For now, only implement FP conditions. e.g. SETONE is
implemented as SETO & SETNE, SETUEQ is SETUO | SETEQ.
- Move x86 target over.

llvm-svn: 57542
 2008-10-15 02:05:31 +00:00
Dan Gohman e7ced74558 FastISel support for exception-handling constructs. 
- Move the EH landing-pad code and adjust it so that it works
   with FastISel as well as with SDISel.
 - Add FastISel support for @llvm.eh.exception and
   @llvm.eh.selector.

llvm-svn: 57539
 2008-10-14 23:54:11 +00:00
Evan Cheng 07d53b1d33 Rename LoadX to LoadExt. 
llvm-svn: 57526
 2008-10-14 21:26:46 +00:00
Chris Lattner 2753955fc0 Change CALLSEQ_BEGIN and CALLSEQ_END to take TargetConstant's as 
parameters instead of raw Constants.  This prevents the constants from
being selected by the isel pass, fixing PR2735.

llvm-svn: 57385
 2008-10-11 22:08:30 +00:00
Dale Johannesen 4f0bd68cfe Add a "loses information" return value to APFloat::convert 
and APFloat::convertToInteger.  Restore return value to
IEEE754.  Adjust all users accordingly.

llvm-svn: 57329
 2008-10-09 23:00:39 +00:00
Evan Cheng 94d14f2d45 Fix PR2850 and PR2863. Only generate movddup for 128-bit SSE vector shuffles. 
llvm-svn: 57210
 2008-10-06 21:13:08 +00:00
Dale Johannesen 8c36a1c09c Make atomic Swap work, 64-bit on x86-32. 
Make it all work in non-pic mode.

llvm-svn: 57034
 2008-10-03 22:25:52 +00:00
Dale Johannesen 5d60c1ebb1 Pass MemOperand through for 64-bit atomics on 32-bit, 
incidentally making the case where the memop is a
pointer deref work.  Fix cmp-and-swap regression.

llvm-svn: 57027
 2008-10-03 19:41:08 +00:00
Dan Gohman 0d1e9a8e04 Switch the MachineOperand accessors back to the short names like 
isReg, etc., from isRegister, etc.

llvm-svn: 57006
 2008-10-03 15:45:36 +00:00
Dale Johannesen 867d549fce Handle some 64-bit atomics on x86-32, some of the time. 
llvm-svn: 56963
 2008-10-02 18:53:47 +00:00
Bill Wendling 68f12ee567 Implement the -fno-builtin option in the front-end, not in the back-end. 
llvm-svn: 56900
 2008-10-01 00:59:58 +00:00
Bill Wendling 1782584f56 Just don't transform this memset into "bzero" if no-builtin is specified. 
llvm-svn: 56888
 2008-09-30 22:05:33 +00:00
Bill Wendling bd09262e97 Add the new `-no-builtin' flag. This flag is meant to mimic the GCC 
`-fno-builtin' flag. Currently, it's used to replace "memset" with "_bzero"
instead of "__bzero" on Darwin10+. This arguably violates the meaning of this
flag, but is currently sufficient. The meaning of this flag should become more
specific over time.

llvm-svn: 56885
 2008-09-30 21:22:07 +00:00
Dale Johannesen f61a84ec43 Remove misuse of ReplaceNodeResults for atomics with 
valid types.  No functional change.

Dan Gohman 6e0548336a Rename ConstantSDNode's getSignExtended to getSExtValue, for 
consistancy with ConstantInt, and re-implement it in terms
of ConstantInt's getSExtValue.

Evan Cheng d77cbe8947 Fix @llvm.frameaddress codegen. FP elimination optimization should be disabled when frame address is desired. Also add support for depth > 0. 
llvm-svn: 56683
 2008-09-26 19:48:35 +00:00
Dale Johannesen 0e32a2c935 Add "inreg" field to CallSDNode (doesn't increase 
its size).  Adjust various lowering functions to
pass this info through from CallInst.  Use it to
implement sseregparm returns on X86.  Remove
X86_ssecall calling convention.

llvm-svn: 56677

Devang Patel 4c758ea3e0 Large mechanical patch. 
s/ParamAttr/Attribute/g
s/PAList/AttrList/g
s/FnAttributeWithIndex/AttributeWithIndex/g
s/FnAttr/Attribute/g

This sets the stage 
- to implement function notes as function attributes and 
- to distinguish between function attributes and return value attributes.

This requires corresponding changes in llvm-gcc and clang.

Arnold Schwaighofer 796a271c5f Change the calling convention used when tail call optimization is enabled from CC_X86_32_TailCall to CC_X86_32_FastCC.

 2008-09-22 14:50:07 +00:00
Bill Wendling 24c79f28b1 Reverting r56249. On further investigation, this functionality isn't needed. 
Apologies for the thrashing.

llvm-svn: 56251
 2008-09-16 21:48:12 +00:00
Bill Wendling 8bc392fb1d - Change "ExternalSymbolSDNode" to "SymbolSDNode". 
- Add linkage to SymbolSDNode (default to external).
- Change ISD::ExternalSymbol to ISD::Symbol.
- Change ISD::TargetExternalSymbol to ISD::TargetSymbol

These changes pave the way to allowing SymbolSDNodes with non-external linkage.

llvm-svn: 56249
 2008-09-16 21:12:30 +00:00
Dan Gohman 38453eebdc Remove isImm(), isReg(), and friends, in favor of 
isImmediate(), isRegister(), and friends, to avoid confusion
about having two different names with the same meaning. I'm
not attached to the longer names, and would be ok with
changing to the shorter names if others prefer it.

llvm-svn: 56189
 2008-09-13 17:58:21 +00:00
Dan Gohman d3fe174c53 Define CallSDNode, an SDNode subclass for use with ISD::CALL. 
Currently it just holds the calling convention and flags
for isVarArgs and isTailCall.

And it has several utility methods, which eliminate magic
5+2*i and similar index computations in several places.

CallSDNodes are not CSE'd. Teach UpdateNodeOperands to handle
nodes that are not CSE'd gracefully.

llvm-svn: 56183
 2008-09-13 01:54:27 +00:00
Dan Gohman effb894453 Rename ConstantSDNode::getValue to getZExtValue, for consistency 
with ConstantInt. This led to fixing a bug in TargetLowering.cpp
using getValue instead of getAPIntValue.

llvm-svn: 56159
 2008-09-12 16:56:44 +00:00
Arnold Schwaighofer dd45bc25ac When tailcallopt is enabled all fastcc calls must have an aligned argument stack size. Add a test case. 
llvm-svn: 56119
 2008-09-11 20:28:43 +00:00
Dale Johannesen 58d084c05b The version of AtomicSDNode::AtomicSDNode used (only) for 
cmp-and-swap reversed the Cmp and Swap arguments; comments
make it clear this is unintentional.  Unfortunately, the
x86 BE had a compensating reversal, which is removed here.
PPC is OK.

From inspection of the Alpha code I think it is OK, but
if somebody has that platform please check it out.  I
cannot test on that platform.

llvm-svn: 56091
 2008-09-11 03:12:59 +00:00
Dan Gohman 39d82f902a Add X86FastISel support for static allocas, and refences 
to static allocas. As part of this change, refactor the
address mode code for laods and stores.

Duncan Sands 83e45acc25 Add trampoline support for the new FastCC calling 
convention (not related to recent Ada testsuite
failures).

llvm-svn: 56054
 2008-09-10 13:11:09 +00:00
Duncan Sands 536c399579 Turn off the new FastCC for the moment. It causes 
a slew of Ada testsuite failures on x86-32 linux.
Seems to be related to the use of float.
