Eric Christopher 22fd29a94a 64-bit fp loads can come straight out of the constant pool, not as 
bad as I'd thought.

Eric Christopher 4bd7047324 SIToFP and FPToSI conversions work only on fp-reg to fp-reg. Move 
some data around and implement a couple of move routines to do this.

Eric Christopher 2cbe0fd956 New "move to fp reg" routine. Use it.

Eric Christopher 82b05d7206 "Strike that, reverse it." -- Mr. Wonka. 
Truncate when truncating, extend when extending.

Eric Christopher 3cf63f1edd Rewrite TargetMaterializeConstant splitting it out into two functions 
for integer and fp constants. Implement todo to use vfp3 instructions
to materialize easy constants if we can.

 2010-09-02 23:43:26 +00:00
Eric Christopher 2020d69800 Clang's -ccc-host-triple was ignoring the arch specifier on my triple, 
I don't need to implement this quite yet - and not for ConstantInt anyhow.

llvm-svn: 112798
 2010-09-02 02:30:46 +00:00
Eric Christopher 92db201e23 This should be TargetMaterializeConstant instead. 
llvm-svn: 112795
 2010-09-02 01:48:11 +00:00
Eric Christopher 6a0333c1ed One definition of isThumb is plenty, thanks.

Eric Christopher 74487fcbe7 Rework arm fast-isel load and store handling. Move offset computation 
into the "address selection" routine and handle constant materialization
for stores.

Eric Christopher 901176a755 Rewrite slightly so we can expand for floating point types easier. 
llvm-svn: 112568
 2010-08-31 01:28:42 +00:00
Eric Christopher bbd1098989 If we have an unhandled type then assert, we shouldn't get here for 
things we can't handle.

llvm-svn: 112559
 2010-08-30 23:48:26 +00:00
Eric Christopher 7a0d8c69cb Do type checks before we bother to do everything else.

Eric Christopher eb47692c22 Add register class hack that needs to go away, but makes it more obvious 
that it needs to go away.  Use loadRegFromStackSlot where possible.

Also, remember to update the value map.

 2010-08-19 00:37:05 +00:00
