Chris Lattner 3f972c9150 Fix PR2423 by checking all indices for out of range access, not only 
indices that start with an array subscript.  x->field[10000] is just 
as bad as (*X)[14][10000].

Dan Gohman eb0cee91f6 Move the point at which FastISel taps into the SelectionDAGISel 
process up to a higher level. This allows FastISel to leverage
more of SelectionDAGISel's infastructure, such as updating Machine
PHI nodes.

Also, implement transitioning from SDISel back to FastISel in
the middle of a block, so it's now possible to go back and
forth. This allows FastISel to hand individual CallInsts and other
complicated things off to SDISel to handle, while handling the rest
of the block itself.

To help support this, reorganize the SelectionDAG class so that it
is allocated once and reused throughout a function, instead of
being completely reallocated for each block.

Dan Gohman 95d1056831 Avoid creating shift-by-zero SDNodes in the common case of 
i8* getelementptr. DAGCombine eliminates these, but this is

Dan Gohman 49e19e906f Factor out the predicate check code from DAGISelEmitter.cpp 
and use it in FastISelEmitter.cpp, and make FastISel
subtarget aware. Among other things, this lets it work
properly on x86 targets that don't have SSE, where it
successfully selects x87 instructions.

Dan Gohman 814f291664 Move the handling of ANY_EXTEND, SIGN_EXTEND_INREG, and TRUNCATE 
out of X86ISelDAGToDAG.cpp C++ code and into tablegen code.
Among other things, using tablegen for these things makes them
friendlier to FastISel.

Tablegen can handle the case of i8 subregs on x86-32, but currently
the C++ code for that case uses MVT::Flag in a tricky way, and it
happens to schedule better in some cases. So for now, leave the
C++ code in place to handle the i8 case on x86-32.

 2008-08-20 00:48:50 +00:00
Dan Gohman 847ebb90b8 Add support for running SelectionDAG if FastISel fails. This is under

Bill Wendling f00f3055d8 Revert r55018 and apply the correct "fix" for the 64-bit sub_and_fetch atomic.

 2008-08-19 23:09:18 +00:00
Dan Gohman 065e24709e Fast-isel is now *minimally* functional. Add a testcase to 
demonstrate the extent of its capabilities. Note that it
only attempts to operate on one of the blocks in this
testcase.

llvm-svn: 55016

Dan Gohman 547ce65467 Use the BuildMI overload that sets up a destination register 
instead of the one that doesn't and then adding it manually.

Owen Anderson c75ae13566 The fast-path still needs to set kill markers and spill/restore points as appropriate. 
With this patch, all of MultiSource/Applications and all of SPEC2000/2006 pass with
the SimpleSpiller and this fast-path enabled.

llvm-svn: 55000
 2008-08-19 20:09:52 +00:00
Dale Johannesen 5afbf510aa Add support for 8 and 16 bit forms of __sync

Change "lock" instructions to be on a separate line.
This is needed to work around a bug in the Darwin
assembler.

Nicolas Geoffray d58c8e759f Update the JIT exception writer to better mimic the codegen exception writer. 
Also skip indirect encoding for platforms that ask for one: we direclty
write an address, not a pointer to the address.

Chris Lattner 604e351456 Change WriteTypeSymbolic/WriteAsOperand to return void instead of 
an ostream, which is just weird.

Rename SC_DEBUG -> ST_DEBUG

Remove static indentation strangeness from WriteConstantInt.  This makes it 
so that large structs are not broken down and printed on multiple lines.  If
there is demand for this to return, there are better ways to implement this.
