Anton Korobeynikov e96503faa1 IT turns out that during jumpless setcc lowering eq and ne were swapped. 
This fixes PR6348

Anton Korobeynikov dd2b2f8cba Reduce (cmp 0, and_su (foo, bar)) into (bit foo, bar). This saves extra instruction. Patch inspired by Brian Lucas!

Duncan Sands b56334b4f2 While this test is testing a problem in the generic part of codegen, 
the problem only shows for msp430 and pic16 which is why it specifies
them using -march.  But it is wrong to put such tests in CodeGen/Generic,
since not everyone builds these targets.  Put a copy of the test in each
of the target test directories.

 2009-11-08 14:27:38 +00:00
Anton Korobeynikov dc2beaa05e It is invalid to infer the value type from the result #0 of the node 
since the instruction might use the other result of different type.

Anton Korobeynikov f1ad2c618a Use special DAG-to-DAG preprocessing to allow mem-mem instructions to be selected. 
Yay for ASCII graphics!

llvm-svn: 84776
 2009-10-21 19:18:28 +00:00
Anton Korobeynikov ccfa3e31f7 RMW preprocessing stuff was incorrect. Grab the stuff from x86 backend and disable some tests until it will be clever enough to handle them.

Anton Korobeynikov 5b8826b4da It seems that OR operation does not affect status reg at all. 
Remove impdef of SRW. This fixes PR4779

Anton Korobeynikov 592638ae05 Allow symbols to start from the digit if target requests it. This allows, e.g. pinning 
variables to specified absolute address. Make use of this feature for MSP430.
This unbreaks PR4776.

Dan Gohman a5b9645c4b Split the Add, Sub, and Mul instruction opcodes into separate 
integer and floating-point opcodes, introducing
FAdd, FSub, and FMul.

For now, the AsmParser, BitcodeReader, and IRBuilder all preserve
backwards compatability, and the Core LLVM APIs preserve backwards
compatibility for IR producers. Most front-ends won't need to change
immediately.

This implements the first step of the plan outlined here:

Eli Friedman 9030c35eb4 Fix for PR4235: to build a floating-point value from integer parts, 
build an integer and cast that to a float.  This fixes a crash 
caused by trying to split an f32 into two f16's.

This changes the behavior in test/CodeGen/XCore/fneg.ll because that 
testcase now triggers a DAGCombine which converts the fneg into an integer
operation.  If someone is interested, it's probably possible to tweak 
the test to generate an actual fneg.

Anton Korobeynikov 6de08cd093 Mark rotl/rotr as expand. This generates pretty ugly code, but this is better than nothing.
