Dan Gohman be474734a5 Add some comments. 
llvm-svn: 102731
 2010-04-30 18:33:41 +00:00
Dan Gohman 57bb73c80b Remove the -disable-16bit command-line option, which is now obsolete. 
llvm-svn: 102730
 2010-04-30 18:30:26 +00:00
Jakob Stoklund Olesen 408459ffa6 Don't use floating point in SimpleRegisterCoalescing. 
Rounding differences causes tests to fail on Linux.

llvm-svn: 102729
 2010-04-30 18:28:11 +00:00
Dan Gohman e0d8f9dbe9 Properly escape edge source and destination labels. 
llvm-svn: 102728
 2010-04-30 18:27:57 +00:00
Dan Gohman 6221b85680 Add -o /dev/null to some tests which don't care about their output. 
llvm-svn: 102722
 2010-04-30 17:42:30 +00:00
Dan Gohman e82c25e878 Apply a patch from Jan Sjodin to fix a compiler abort on vector 
comparisons sign-extended to a different bitwidth than the
comparison operands.

llvm-svn: 102721
 2010-04-30 17:19:19 +00:00
Daniel Dunbar d411fcbc4c Regenerate. 
llvm-svn: 102720
 2010-04-30 17:12:26 +00:00
Daniel Dunbar e96fcbb085 Default OPTIMIZE_OPTION to -O2 on FreeBSD, at the request of the Clang/FreeBSD 
folks. LLVM/Clang is miscompiled by the standard GCC at -O3.

llvm-svn: 102719
 2010-04-30 17:12:23 +00:00
Benjamin Kramer 2073fcac2d SmallBitVector: Rework find_first/find_next and tweak test to test them (at least on 64 bit platforms). 
llvm-svn: 102712
 2010-04-30 13:40:27 +00:00
Benjamin Kramer e2a98b1e90 Implement a read/write operator[] for SmallBitVector with a proxy class. 
llvm-svn: 102709
 2010-04-30 12:29:39 +00:00
Benjamin Kramer 120e6b748b Make sure SmallBitVector actually uses the small case and fix latent bugs. 
- We can't use PointerIntPair here since we require the discrimination bit to be in the LSB.

llvm-svn: 102707
 2010-04-30 11:34:01 +00:00
Evan Cheng 5f2314f3a3 Fix test. 
llvm-svn: 102694
 2010-04-30 06:00:56 +00:00
Evan Cheng 5117a555e0 Another sibcall bug. If caller and callee calling conventions differ, then it's only safe to do a tail call if the results are returned in the same way. 
llvm-svn: 102683
 2010-04-30 01:12:32 +00:00
Dan Gohman 587e0800e5 Temporarily disable SelectionDAG kill flags, which are causing trouble. 
llvm-svn: 102680
 2010-04-30 00:32:51 +00:00
Jeffrey Yasskin 0a1513902f Fix the OProfileJITEventListener build after r101844 removed 
MachineFunction::DefaultDebugLoc.  We now use the same technique as
DwarfDebug::beginFunction to find the starting line number for a
function.

llvm-svn: 102679
 2010-04-30 00:16:10 +00:00
Dan Gohman ac55510c4e Set register kill flags on the SelectionDAG path, at least in the 
easy cases.

llvm-svn: 102678
 2010-04-30 00:08:21 +00:00
Jakob Stoklund Olesen 8d4214578d Reject really weird coalescer case when trying to merge identical subregisters 
of different register classes. e.g.

  %reg1048:3<def> = EXTRACT_SUBREG %RAX<kill>, 3

Where %reg1048 is a GR32 register. This is not impossible to handle, but it is
pretty hard and very rare.

This should unbreak the dragonegg builder.

llvm-svn: 102672
 2010-04-29 23:47:46 +00:00
Nick Lewycky 83e3060f08 The llc -f flag was removed. 
llvm-svn: 102670
 2010-04-29 23:37:44 +00:00
Dan Gohman 0fd54fbbcf Don't leave Base.FrameIndex uninitialized, so that it doesn't 
print randomly in debug output.

llvm-svn: 102668
 2010-04-29 23:30:41 +00:00
Chris Lattner 9d186478c0 add some more (void)'s to prototypes for PR6961 
llvm-svn: 102667
 2010-04-29 23:27:32 +00:00
Dan Gohman 35cd68c888 Fix typos in assertion strings. 
llvm-svn: 102666
 2010-04-29 23:25:34 +00:00
Jakob Stoklund Olesen e2550f4f93 Slightly verboser debug spew from coalescer 
llvm-svn: 102663
 2010-04-29 22:21:48 +00:00
Devang Patel 02b2574d06 Missed earlier. This is part of previous check-in. (r102661 - refactor.) 
llvm-svn: 102662
 2010-04-29 20:48:12 +00:00
Devang Patel 0395553e35 Refactor. 
llvm-svn: 102661
 2010-04-29 20:40:36 +00:00
Dale Johannesen 6feac8a39b Make naked functions work on PPC. 
llvm-svn: 102657
 2010-04-29 19:32:19 +00:00
Devang Patel 080e4fb2f0 Print variable scope name in DEBUG_VALUE comment. Useful in some cases. e.g. 
##DEBUG_VALUE: runOnMachineFunction:this <- RDI+0
	##DEBUG_VALUE: runOnMachineFunction:fn <- RSI+0
	##DEBUG_VALUE: DeadDefs <- undef ## SimpleRegisterCoalescing.cpp:2706
	##DEBUG_VALUE: getRegInfo:this <- [%rsp+$56]+$0
	##DEBUG_VALUE: getTarget:this <- [%rsp+$56]+$0

llvm-svn: 102655
 2010-04-29 18:52:10 +00:00
Evan Cheng 6e7ca24907 Remove DBG_VALUE which reference dead stack slots. 
llvm-svn: 102654
 2010-04-29 18:51:00 +00:00
Devang Patel a46953d281 DO not push DBG_VALUE machine instructions for inlined fuction arguments in entry block. 
llvm-svn: 102653
 2010-04-29 18:50:36 +00:00
Evan Cheng d433757315 Add DenseMapInfo for int. 
llvm-svn: 102652
 2010-04-29 18:50:35 +00:00
Dan Gohman 0cc5629f4e llc no longer requires the -f option to overwrite files. 
llvm-svn: 102651
 2010-04-29 18:46:52 +00:00
Bob Wilson 1905e2be86 Don't remove libLTO.dylib if it's not being installed in Developer/usr/lib; 
just leave it in Developer/usr/local/lib.

llvm-svn: 102646
 2010-04-29 18:04:29 +00:00
Dan Gohman 4695c20f8c Elaborate on a comment. 
llvm-svn: 102637
 2010-04-29 16:57:54 +00:00
Daniel Dunbar c1626e3317 Remove dead option. 
llvm-svn: 102621
 2010-04-29 16:29:02 +00:00
Duncan Sands 76d6217906 Verify metadata harder. In particular, check that module 
level metadata does not have any function local operands.
This would have caught the problem found in PR6112.

llvm-svn: 102620
 2010-04-29 16:10:30 +00:00
Duncan Sands d4886f1fbe Fix comment typo. 
llvm-svn: 102612
 2010-04-29 12:32:45 +00:00
Evan Cheng 5c864b42b2 Add comment. 
llvm-svn: 102606
 2010-04-29 06:58:53 +00:00
Torok Edwin 63dd86352e Fix PR6910. 
Limit alignment in SmallVector 8, otherwise GCC assumes 16 byte alignment.
opetaror new, and malloc only return 8-byte aligned memory on 32-bit Linux,
which cause a crash if code is compiled with -O3 (or -ftree-vectorize) and some
SmallVector code is vectorized.

llvm-svn: 102604
 2010-04-29 06:43:12 +00:00
Evan Cheng 923679f929 Re-enable 102565 with fixes. 
llvm-svn: 102602
 2010-04-29 06:33:38 +00:00
Nick Lewycky d16766e091 Fix typo. 
llvm-svn: 102599
 2010-04-29 05:54:29 +00:00
Evan Cheng 38dfa5cf20 Load folding tail call should not use ebp / rbp after it's popped. PEI 
should use esp / rsp to reference frame instead.

llvm-svn: 102596
 2010-04-29 05:08:22 +00:00
Mon P Wang b0a0a26df1 Add support for assemblers that don't support periods in a name 
llvm-svn: 102594
 2010-04-29 04:00:56 +00:00
Evan Cheng d65a1e782b Temporarily disable my changes to unbreak the build. 
llvm-svn: 102590
 2010-04-29 03:34:19 +00:00
Evan Cheng 5fb45a2b85 Do not generate duplicate dbg_value instructions for function arguments. 
llvm-svn: 102585
 2010-04-29 01:40:30 +00:00
Dan Gohman d9e7322c9a Fix missing #include. 
llvm-svn: 102584
 2010-04-29 01:39:13 +00:00
Evan Cheng 70a0145d7c Avoid emitting a dbg_value machineinstr that's not going to be inserted into entry block. 
llvm-svn: 102581
 2010-04-29 01:23:55 +00:00
Evan Cheng 250e917e9d Frame index can be negative. 
llvm-svn: 102577
 2010-04-29 01:13:30 +00:00
Evan Cheng f4336ebb2a Check Reg against zero. 
llvm-svn: 102573
 2010-04-29 00:59:34 +00:00
Evan Cheng a5a8f76cea - Really preserve dbg_value instructions when the register is spilled. 
- Also, update dbg_value is the value is being re-matted from a frame slot, e.g. fixed slots for arguments.

llvm-svn: 102565
 2010-04-28 23:52:26 +00:00
Devang Patel bb728e17d3 tidy up. 
llvm-svn: 102558
 2010-04-28 23:24:13 +00:00
Kevin Enderby 4822841b82 Fixed the word sized Bit Scan Forward/Reverse instructions, they needed the 
Operand size override prefix to be part of their records.
