Chris Lattner b77ba73a29 Add support for calls that pass and return legal vectors. 
llvm-svn: 28340
 2006-05-16 23:39:44 +00:00
Chris Lattner aa40ec1b32 Instead of implementing LowerCallTo directly, let the default impl produce an 
ISD::CALL node, then custom lower that.  This means that we only have to handle
LEGAL call operands/results, not every possible type.  This allows us to
simplify the call code, shrinking it by about 1/3.

llvm-svn: 28339
 2006-05-16 22:56:08 +00:00
Chris Lattner aaa23d953f Add a new ISD::CALL node, make the default impl of TargetLowering::LowerCallTo 
produce it.

Chris Lattner 318f0d2122 Vector args passed in registers don't reserve stack space.

Chris Lattner f4d08dd0d3 Another testcase that shouldn't need vrsave twiddling

Chris Lattner 4302e8fb67 Switch the PPC backend over to using FORMAL_ARGUMENTS for formal argument 
handling.  This makes the lower argument code significantly simpler (we
only need to handle legal argument types).

Incidentally, this also implements support for vector argument registers,
so long as they are not on the stack.

Chris Lattner c7df70db57 Implement the custom lowering hook right, returning values for all of the 
arguments at once.

Chris Lattner 7b8b8bbbf9 Fix a bug I introduced yesterday, which broke functions with *no* arguments. 
llvm-svn: 28326
 2006-05-16 17:08:35 +00:00
Reid Spencer 40f1b1321d Make sure to default ${prefix} to /usr/local if the user didn't specify it. 
This assists with getting around configure's late binding values so that
our LLVM variables don't end up with a "NONE" prefix.

Evan Cheng 9fee442e63 X86 integer register classes naming changes. Make them consistent with FP, vector classes.

Evan Cheng d985d66781 Allow patterns to refer to physical registers that belong to multiple 
register classes.

Reid Spencer 540c1b95f1 Make sure that $(CXX.Flags) is passed to the linker so that the same options 
with which source is compiled are used when linking. This matters when a
project is using the LLVM makefiles and overrides CXXFLAGS to specify new
flags to use.

Chris Lattner 3d82699605 Add a chain to FORMAL_ARGUMENTS. This is a minimal port of the X86 backend, 
it doesn't currently use/maintain the chain properly.  Also, make the
X86ISelLowering.cpp file 80-col clean.

Vladimir Prus 788db2c812 Replace "../whatever.td" with "whatever.td", so that out-of-tree backends 
can just add lib/Target to TableGen includes.

Reid Spencer 1f54156a01 For PR778:

Reid Spencer 1053658517 When linking, make sure the project libraries are linked before the LLVM 
libraries. This ensures that the project's libraries (which most likely
depend on LLVM libraries) come first on the command line and can thus be
resolved by the LLVM libraries that appear later.

Chris Lattner 957cb6733a Move function-live-in-handling code from the sdisel code to the scheduler. 
This code should be emitted after legalize, so it can't be in sdisel.

Note that the EmitFunctionEntryCode hook should be updated to operate on the
DAG.  The X86 backend is the only one currently using this hook.

Reid Spencer 3d01718c70 Upgrade in preparation for doxygen 1.4.4. The config file format changed, 
there are new/different css styles to support, and the footer was woefully
out of date.
