Jim Grosbach 96ef39a8db Revert 119600 to unbreak the build. Francois, please investigate.

Dale Johannesen ed0d840838 Do not throw away alignment when generating the DAG for 
memset; we may need it to decide between MOVAPS and MOVUPS
later.  Adjust a test that was looking for wrong code.
PR 3866 / 8675131.

Jim Grosbach cfb66204b7 Refactor the ARM PICADD and PICLDR* instructions to really be pseudos and not 
just pretend to be.

Francois Pichet ce52087bf3 Appease MSVC 2008: you can't use keyword this inside EXPECT_EQ(). 
This is because of bug 331418 on Microsoft Connect.

John Thompson 488051f1a6 Fixed to use input redirection for source - to eliminate .s output.

 2010-11-18 00:50:20 +00:00
Jim Grosbach 8e7f8df4a2 Refactor a few ARM load instructions to better parameterize things and re-use 
common encoding information.

Ted Kremenek 5d304a34c6 CursorVisitor: switch remaining expressions over 
to the data-recursion algorithm.  CursorVisitor
now no longer subclasses StmtVisitor.

Jim Grosbach 56f471726c Clean up LEApcrel instuction(s) a bit. It's not really a Pseudo, so don't mark 
it as such. Add some encoding information.

Dan Gohman 7e6b393e66 Factor out the code for purging a SCEV from all the various memoization maps. 
Some of these maps may merge in the future, but for now it's convenient to have
a utility function for them.

llvm-svn: 119587
 2010-11-17 23:28:48 +00:00
Ted Kremenek 7df92ae92b Make definition of CXTranslationUnitImpl private 
to libclang.

 2010-11-17 23:24:11 +00:00
Dan Gohman 7ee1bbb76c Merge the implementations of isLoopInvariant and hasComputableLoopEvolution, and 
memoize the results. This improves compile time in code which highly complex
expressions which get queried many times.

 2010-11-17 23:21:44 +00:00
Argyrios Kyrtzidis af84ec0a96 Introduce option -Wargument-larger-than[=N] which warns about function definitions if they take by-value 
or return by-value any POD that is larger than some threshold (default is 64 bytes).

Implements rdar://8548050.

 2010-11-17 23:11:54 +00:00
Sean Callanan afe16a71f7 Added support for constant strings of the form @"this-is-a-string". 
They are replaced with calls to the CoreFoundation function 
CFStringCreateWithBytes() by a portion of the IRForTarget pass.

llvm-svn: 119582
 2010-11-17 23:00:36 +00:00
Sean Callanan ac6429fc9a Whitespace fix.

Wesley Peck 307e4688c5 Now that the MBlaze backend is in its own directory, split the test cases into multiple files for different types of instructions. 
llvm-svn: 119580
 2010-11-17 22:54:43 +00:00
Dan Gohman 534749bf70 Make SCEV::getType() and SCEV::print non-virtual. Move SCEV::hasOperand 
to ScalarEvolution. Delete SCEV::~SCEV. SCEV is no longer virtual.

Rafael Espindola cfaaddaee0 Don't warn about 
clang -w -c foo.s
Helps with the gdb testsuite.

Dale Johannesen 0659c8f157 These tests are looking for library function names that 
appear to differ on Linux.  Try to make them pass on Linux.
Would be good for a Linux person to review this.

Douglas Gregor b4a7c0385d Do not produce "purely informative" code completion results for 
Objective-C message sends, which have only whitespace in their
TypedText chunk. Such results have no purpose.

Marcin Swiderski af56739355 In EvalArguments allow for evaluation of first argument always as a lvalue. Will be used for CXXOperatorCallExpr that represents method call.

Bob Wilson 881b45ccdf Change ARMGlobalMerge to keep BSS globals in separate pools. 
This completes the fixes for Radar 8673120.

llvm-svn: 119566
 2010-11-17 21:25:39 +00:00
Bob Wilson 4c8ab19c22 Fix ARMGlobalMerge pass to check if globals are entirely within range. 
It is generally not sufficient to check if the starting offset is in range
of the maximum offset that can be efficiently used for the target.

llvm-svn: 119565
 2010-11-17 21:25:36 +00:00
Bob Wilson 59182fb4b5 Change the symbol for merged globals from "merged" to "_MergedGlobals". 
This makes it more clear that the symbol is an internal, compiler-generated
name and gives a little more description about its contents.

llvm-svn: 119564
 2010-11-17 21:25:33 +00:00
Bob Wilson f796d4b469 Fix the ARMGlobalMerge pass to look at variable sizes instead of pointer sizes. 
It was mistakenly looking at the pointer type when checking for the size of
global variables.  This is a partial fix for Radar 8673120.

llvm-svn: 119563
 2010-11-17 21:25:27 +00:00
Dan Gohman afd6db9932 Move SCEV::isLoopInvariant and hasComputableLoopEvolution to be member 
functions of ScalarEvolution, in preparation for memoization and
other optimizations.

Jim Grosbach 08c562bba6 Make the ARM BR_JTadd instruction an explicit pseudo and lower it properly 
in the MC lowering process.

Evan Cheng 39c81c0a55 Avoid isel movcc of large immediates when the large immediate is available in a register. These immediates aren't free. 
llvm-svn: 119558
 2010-11-17 20:56:30 +00:00
Dan Gohman 1ee6d24072 Reference ScalarEvolution by name rather than directly in LICM, 
to avoid an unneeded dependence.

 2010-11-17 20:50:07 +00:00
Duncan Sands 39d77131a1 Before replacing a phi node with a different value, it 
needs to be checked that this won't break LCSSA form.
Change the existing checking method to a more direct one:
rather than seeing if all predecessors belong to the loop,
check that the replacing value is either not in any loop or
is in a loop that contains the phi node.

Dan Gohman d3a32ae4c8 Verify SCEVAddRecExpr's invariant in ScalarEvolution::getAddRecExpr 
instead of in SCEVAddRecExpr's constructor, in preparation for an
upcoming change.
