Dan Gohman b16a7783c5 Add FastISel support for floating-point operations. 
llvm-svn: 55021
 2008-08-20 00:23:20 +00:00
Dan Gohman a3e4d5a5e1 Add FastISel support for several more binary operators.

 2008-08-20 00:11:48 +00:00
Eli Friedman 02d4a78688 Get rid of the bogus -depth +0 argument; I really have no clue what the 
heck it does on Darwin, but it's not part of POSIX, and the GNU version 
of find errors out on it.

On a side note, there are a couple of new failures due to tests 
including OS X specific headers.

 2008-08-20 00:02:01 +00:00
Bill Wendling e79740851f Add support for the __sync_sub_and_fetch atomics and friends for X86. The code 
was already present, but not hooked up to anything.

 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
 2008-08-19 22:37:59 +00:00
Dan Gohman 697284fe0a Add code to call FastISel, and a command-line option to enable it.

 2008-08-19 21:26:29 +00:00
Dan Gohman 2dbebd7db5 For now, restrict FastISel to instructions that only involve one 
register class.

llvm-svn: 55008
 2008-08-19 20:58:14 +00:00
Dan Gohman 98e6f1c48a Factor out the code to scan an instruction's operands into a 
helper function.

llvm-svn: 55007
 2008-08-19 20:56:30 +00:00
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.

llvm-svn: 55006
 2008-08-19 20:46:54 +00:00

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 
builtins on X86.

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

Ted Kremenek 67102b281e Patch by Zhongxing Xu! 
This patch extends BasicStoreManager::getInitialStore() to include code that symbolicates input variables.
It also removes redundant handling of ImplicitParamDecl, since it is a subclass of VarDecl.

 2008-08-19 16:51:45 +00:00
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.

Steve Naroff ad7013b1e6 Fix crasher in RewriteObjC::RewriteObjCSynchronizedStmt(). Can't depend on the source locations of the sync expression (since it may have been rewritten. 
Fixes <rdar://problem/6156363> clang ObjC rewriter: rewriting attached file causes assertion failure: invalid FileID

llvm-svn: 54985

Chris Lattner 585297e851 more cleanups, random methods shouldn't return ostreams.

llvm-svn: 54982
 2008-08-19 05:06:27 +00:00
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.

 2008-08-19 04:28:07 +00:00
Chris Lattner e36fd8a2ff Reid had to call this class "slot machine" out of some strange reference
