Dan Gohman e8f9a00424 Fix FastISel to recognize that the last block in the function does 
not have a fall-through successor.

llvm-svn: 55033
 2008-08-20 01:17:01 +00:00
Dan Gohman 98265cae87 Fix a leak in the FastISel code that Chris pointed out.

Dan Gohman eaef5f612a Add a -march line for this test, and run it on x86-64 too for fun.

llvm-svn: 55029
 2008-08-20 00:48:50 +00:00
Dan Gohman 847ebb90b8 Add support for running SelectionDAG if FastISel fails. This is under 
a command-line option, so that the default behavior is an abort, which
is useful for exposing code that isn't supported yet.

llvm-svn: 55028
 2008-08-20 00:47:54 +00:00

Bill Wendling f00f3055d8 Revert r55018 and apply the correct "fix" for the 64-bit sub_and_fetch atomic. 
Just expand it like the other X-bit sub_and_fetches.

 2008-08-20 00:11:48 +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.

llvm-svn: 55018
 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

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

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.

MachineRegisterInfo::use_iterator.

Gordon Henriksen d930f913e6 Rename some GC classes so that their roll will hopefully be clearer. 
In particular, Collector was confusing to implementors. Several
thought that this compile-time class was the place to implement
their runtime GC heap. Of course, it doesn't even exist at runtime.
Specifically, the renames are:

  Collector               -> GCStrategy
  CollectorMetadata       -> GCFunctionInfo
  CollectorModuleMetadata -> GCModuleInfo
  CollectorRegistry       -> GCRegistry
  Function::getCollector  -> getGC (setGC, hasGC, clearGC)

Several accessors and nested types have also been renamed to be
consistent. These changes should be obvious.

- add ../ on several include in X86/AsmPrinter/

Chris Lattner edceac3861 avoid an extraneous std::string construction 
llvm-svn: 54875
 2008-08-17 07:24:08 +00:00
Chris Lattner 17f7165f84 Rework the routines that convert AP[S]Int into a string. Now, instead of 
returning an std::string by value, it fills in a SmallString/SmallVector
passed in.  This significantly reduces string thrashing in some cases.

More specifically, this:
 - Adds an operator<< and a print method for APInt that allows you to 
   directly send them to an ostream.
 - Reimplements APInt::toString to be much simpler and more efficient
   algorithmically in addition to not thrashing strings quite as much.

This speeds up llvm-dis on kc++ by 7%, and may also slightly speed up the
asmprinter.  This also fixes a bug I introduced into the asmwriter in a
previous patch w.r.t. alias printing.

Chris Lattner 84b94f77c6 add a new raw_ostream class which is an extremely high performance ostream that 
can *only* output data (no seeking, reading, etc).  This is adapted from the
clang "-E outputter", and is roughly 10% faster than stdio on darwin and 30%
(or more) faster than std::ostream.

Devang Patel fdee7034b3 The pass manager is not able to schedule -loop-deletion -loop-index-split. 
The loop-deletion pass does not preserve dom frontier, which is required by
loop-index-split. When the PM checks dom frontier for loop-index-split, it has
already verified that lcssa is availalble. However, new dom frontier forces new
loop pass manager, which does not  have lcssa yet.

The PM should recheck availability of required analysis passes in such cases.

Bruno Cardoso Lopes 02ff450f13 Added Mips support for DYNAMIC_STACKALLOC 
Fixed bug in adjustMipsStackFrame, which was breaking
while trying to access a dead stack object index. Also added
one more alignment before fixing the callee saved registers
stack offset adjustment.

FPROUND_F80_F32, FPROUND_PPCF128_F32, 
FPROUND_F80_F64, FPROUND_PPCF128_F64

Support for soften float fp_round operands is added, Mips 
needs this to round f64->f32.

Also added support to soften float FABS result, Mips doesn't 
support double fabs results while in 'single float only' mode.
