Eric Christopher 2c8e7f421c Remove assert, add comment. 
llvm-svn: 115009
 2010-09-29 00:49:09 +00:00
Eric Christopher a86a6d2fed 32-bit constant ints only for now. 
llvm-svn: 115001
 2010-09-28 22:47:54 +00:00
Eric Christopher 953b1afd5f Integer materialization needed the same thinko change. 
llvm-svn: 114994
 2010-09-28 21:55:34 +00:00
Eric Christopher 7990df1ae2 Rework builtin handling and call setup. The builtin handling 
now takes a libcall operand, sets up the arguments correctly and
handles stack adjustments.

llvm-svn: 114934
 2010-09-28 01:21:42 +00:00
Eric Christopher 6f98bfd870 Fix fp constant loads to have a destination register. 
llvm-svn: 114930
 2010-09-28 00:35:09 +00:00
Eric Christopher 0720611e3a Insert missing coherency in comment. Add a quick check for hardware 
divide support also.

llvm-svn: 114812
 2010-09-27 06:02:23 +00:00

llvm-svn: 114263
 2010-09-18 02:32:38 +00:00

 2010-09-17 22:28:18 +00:00
Eric Christopher 8b9126694d Emit libcalls for SDIV, this requires some call infrastructure 
that needs to be shared a bit more widely around.

llvm-svn: 113886
 2010-09-14 23:03:37 +00:00
Eric Christopher 72497e5d90 Start sketching out ARM fast-isel calls.

more clear.  No functional change.

llvm-svn: 113565
 2010-09-10 00:34:35 +00:00
Eric Christopher 22fd29a94a 64-bit fp loads can come straight out of the constant pool, not as 
bad as I'd thought.

llvm-svn: 113561
 2010-09-09 23:50:00 +00:00
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.

llvm-svn: 113546
 2010-09-09 21:44:45 +00:00

 2010-09-09 20:49:25 +00:00
Eric Christopher 82b05d7206 "Strike that, reverse it." -- Mr. Wonka. 
Truncate when truncating, extend when extending.

llvm-svn: 113536
 2010-09-09 20:36:19 +00:00

llvm-svn: 113453
 2010-09-09 00:19:41 +00:00
Eric Christopher c3e9c404aa Very basic compare support.

 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. 
llvm-svn: 112793
 2010-09-02 01:39:14 +00:00
Eric Christopher 74487fcbe7 Rework arm fast-isel load and store handling. Move offset computation

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. 
llvm-svn: 112039

 2010-08-24 01:10:04 +00:00
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.

llvm-svn: 111883
 2010-08-24 00:50:47 +00:00
