Nate Begeman e74dfbb9ce Do the right thing and enable 64 bit regs under the control of a subtarget 
option.  Currently the only way to enable this is to specify the
64bitregs mattr flag.  It is never enabled by default on any config yet.

Nate Begeman 0b71e007ef First bits of 64 bit PowerPC stuff, currently disabled. A lot of this is 
purely mechanical.

John Criswell d122b68735 Use %s instead of hard coding the input filename. 
This allows the test to work when srcdir != objdir.

Chris Lattner acf3d627b9 update this a little bit to talk about the dag combiner and remove inaccuracies. 
This still doesn't talk about autogen much

llvm-svn: 23757

Chris Lattner d869bec4fe Remove some dead code: the ORI/ORIS cases are autogen'd. This makes 
SelectIntImmediateExpr dead.

Chris Lattner 6b22d2554a Implement the last major missing piece in the DAG isel generator: when emitting 
a pattern match, make sure to emit the (minimal number of) type checks that
verify the pattern matches this specific instruction.  This allows FMA32
patterns to not match double expressions for example.

Chris Lattner b986f471be Use getExtLoad here instead of getNode, as extloads produce two values. This 
fixes a legalize failure on SPASS for itanium.

from the .td file that correspond to it

llvm-svn: 23736
 2005-10-14 22:44:13 +00:00
Nate Begeman 9d7008b08d Properly split f32 and f64 into separate register classes for scalar sse fp 
fixing a bunch of nasty hackery

llvm-svn: 23735
 2005-10-14 22:06:00 +00:00
Nate Begeman c41e1be2e8 Remove an unnecsesary file. PPC32 and PPC64 share architected registers. 
We will decide with subtarget support whether we ever use an i64 register
class.

Chris Lattner c4db8f4163 Now that we have int/fp lattice values, implement the SDTCisOpSmallerThanOp 
type constraint.  This lets tblgen realize that it doesn't need any dynamic
type checks for fextend/fround on PPC (and many other targets), because there
are only two fp types.
