Zhongxing Xu 23030c9004 Replace code with a method call. No functionality change. 
llvm-svn: 101876
 2010-04-20 05:40:40 +00:00
Chris Lattner 38c1a1a247 teach cellspu how to return i8 and i16 from calls, 
patch by Kalle Raiskila!

Chris Lattner 66e809acc0 remove a bunch of ad-hoc code to simplify instructions from 
loop unswitch, and use inst simplify instead.  It is more
powerful and less duplication.

llvm-svn: 101874
 2010-04-20 05:33:18 +00:00
Chris Lattner c707fa9651 move some select simplifications out out instcombine into 
inst simplify.  No functionality change.

 2010-04-20 05:19:10 +00:00
Chris Lattner 5814d9d9da RewriteLoopBodyWithConditionConstant can end up rewriting the 
condition we're unswitching on.  In this case, don't try to
simplify the second copy of the loop which may be dead or not,
but is probably a constant now.  This fixes PR6879

Anders Carlsson 3d4218570a Assert that the path from the derived to the base class in CodeGenFunction::GetAddressOfBaseClass is not ambiguous.

Chris Lattner c239eb79bd reapply 'reject forward references to functions whose type don't match' 
now that the testsuite has been updated.

Chris Lattner 3da9a2a3a9 revert r101863, whcih is causing Sema/altivec-init.c to fail on a ton 
of buildbots with:

error: 'error' diagnostics expected but not seen: 
  Line 9: too few elements in vector initialization (expected 8 elements, have 2)
1 warning and 1 error generated.

 2010-04-20 03:37:34 +00:00
John McCall 0f55a035cf Restore r101841 without modification. Also mark 'operator delete' as used for 
actual delete expressions, not just new expressions.

Chris Lattner b6410e168c add __builtin_[r]index. Perhaps all LIBBUILTIN's should get 
these or something?

llvm-svn: 101858

John McCall 21f8d1d643 Use __SIZE_TYPE__ as suggested by dgregor.

 2010-04-20 01:26:56 +00:00
Bill Wendling 467e6c2deb The visitXOR method can return the same SDNode. If so, we don't want to delete 
it as it's not dead.

 2010-04-20 01:25:01 +00:00
Chris Lattner 4025306a91 disable optimizations in this directory for MSVC9. This avoids 
an optimizer infinite loop on the file, PR6866.

Johnny Chen 2161e9f03b Better error-handling for DisassembleThumb2DPModImm() with 2-reg operands where 
d==15 is considered illegal.  Return false instead of assert().

Eric Christopher 64831c6a4c Remove the palignr intrinsics now that we lower them to vector shuffles, 
shifts and null vectors. Autoupgrade these to what we'd lower them to.

Add a testcase to exercise this.

llvm-svn: 101851
 2010-04-20 00:59:54 +00:00
Dan Gohman eadc04badc Remove this debug output; it isn't that useful, and it's incomplete 
in the case where a basic block is split.

llvm-svn: 101850
 2010-04-20 00:56:44 +00:00
Dan Gohman e450d7444d Sink DebugLoc handling out of SelectionDAGISel into FastISel and 
SelectionDAGBuilder, where it doesn't have to be as complicated.

Chris Lattner aedb8a3535 make CallGraphNode dtor abort if a node is deleted when there are still 
references to it.

 2010-04-20 00:47:34 +00:00
Chris Lattner a5cdd5e6a2 make the inliner do less work for leaf functions. 
llvm-svn: 101846
 2010-04-20 00:47:08 +00:00
Chris Lattner e93846762a Fix rdar://7879828 - crash in CallGraph, a self host issue. 
Arg promotion was deleting call graph nodes that still had references
from the 'indirect' CGN.  Like the inliner, it should only delete the
function if all references are gone.

 2010-04-20 00:46:50 +00:00
Dan Gohman 3df671a81c Remove MachineFunction's DefaultDebugLoc member, and make DwarfDebug.cpp 
responsible for figuring out what that's supposed to be on its own.

llvm-svn: 101844
 2010-04-20 00:37:27 +00:00
Dan Gohman ca35aa1122 Reapply the removal of SelectionDAGISel's BB, with a fix for the case 
where multiple blocks are emitted; functions which do this need to return
the new BB so that their callers can stay current.

llvm-svn: 101843
 2010-04-20 00:29:35 +00:00
John McCall 75b4746e7d Don't bother looking for (or diagnosing problems with) the 'operator delete' 
associated with a new expression if -fno-exceptions is set.

llvm-svn: 101841
 2010-04-20 00:22:43 +00:00
Bob Wilson 92a4685dd2 Fix tests for Neon load/store intrinsics to match the i8* types expected by 
the intrinsics.  The reason for those i8* types is that the intrinsics are
overloaded on the vector type and we don't have a way to declare an intrinsic
where one argument is an overloaded vector type and another argument is a
pointer to the vector element type.  The bitcasts added here will match what
the frontend will typically generate when these intrinsics are used.

Johnny Chen f3dd8b9487 More IT instruction error-handling improvements from fuzzing. 
llvm-svn: 101839
 2010-04-20 00:15:41 +00:00
Douglas Gregor dc35ef9279 Do not diagnose unused-parameter errors in template instantiations. We 
will already have done so when the template is declared.

llvm-svn: 101838

Dan Gohman be2e727a38 Revert 101825, which is causing trouble. 
llvm-svn: 101832
 2010-04-19 23:34:15 +00:00
Dan Gohman 35bc4d46cb Make BreakAntiDependencies' SUnits argument const, and make the Begin 
and End arguments by-value rather than by-reference.

llvm-svn: 101830
 2010-04-19 23:11:58 +00:00
Johnny Chen e62b680965 Better error handling of invalid IT mask '0000', instead of just asserting. 
llvm-svn: 101827
 2010-04-19 23:02:58 +00:00
Douglas Gregor c4df407604 Keep track of the actual storage specifier written on a variable or 
function declaration, since it may end up being changed (e.g.,
"extern" can become "static" if a prior declaration was static). Patch
by Enea Zaffanella and Paolo Bolzoni.

llvm-svn: 101826
 2010-04-19 22:54:31 +00:00
Dan Gohman 8cccc542f6 Eliminate SelectionDAGISel's "current block" member. Just pass it as 
an argument to things that need it.

llvm-svn: 101825
 2010-04-19 22:51:14 +00:00
Dan Gohman 5ccd0b3686 Delete an unnecessary reference to SelectionDAGISel::BB. 
llvm-svn: 101824
 2010-04-19 22:48:45 +00:00
Dan Gohman 7c0303a059 Eliminate the CurMBB member from SelectionDAGBuilder. For places that 
need it, just pass around the parent block of the current instruction
explicitly.

llvm-svn: 101822
 2010-04-19 22:41:47 +00:00
Douglas Gregor f4cd8f4ece Only suppress the "extern variable has an initializer" warning when the extern entity being initialized is const. 
llvm-svn: 101821
 2010-04-19 22:34:40 +00:00
Dan Gohman e637ff5e9a Remove the Expr member from IVUsers. Instead of remembering the expression, 
just ask ScalarEvolution for it on demand. This helps IVUsers be more robust
in the case of expressions changing underneath it. This fixes PR6862.

llvm-svn: 101819
 2010-04-19 21:48:58 +00:00
Douglas Gregor c81ca09830 Disable the "'extern' variable has an initializer" warning in C++, 
since it makes sense there to have const extern variables. Fixes
PR6495.

Johnny Chen 777346e749 According to A8.6.16 B (Encoding T3) and A8.3 Conditional execution -- A8.3.1 
Pseudocode details of conditional, Condition bits '111x' indicate the
instruction is always executed.  That is, '1111' is a leagl condition field
value, which is now mapped to ARMCC::AL.

Also add a test case for condition field '1111'.
