Richard Smith 5503805555 Mangling of undeduced 'auto' types, as specified by Itanium C++ ABI. 
llvm-svn: 126140
 2011-02-21 20:10:02 +00:00
Richard Smith b2bc2e6752 Tweaks to C++0x deduced auto type support: 
* Flag indicating 'we're parsing this auto typed variable's initializer' moved from VarDecl to Sema
 * Temporary template parameter list for auto deduction is now allocated on the stack.
 * Deduced 'auto' types are now uniqued.

Ted Kremenek bda17491c4 Fix call to send_error() in scan-view. An int error code is expected but a string was being sent. Patch by Andrew Price!

John McCall 15dd404c46 Don't warn about static const integral data members with in-line constant 
initializers just because they don't have a proper out-of-line definition.
Such code is technically ill-formed but is too common and too unlikely to be
a problem to be seriously worth worrying about.

David Greene 55820a6b7b Add a convenience tool for doing comparison builds of the LLVM 
ecosystem.  This is a handy utility for checking changes before
committing them to the repository.

Chris Lattner 22b7495ec8 Better OpenBSD support, patch by Amit Kulkarni. I have no way to test 
that this doesn't break gold, but it seems reasonable to me.

Duncan Sands ecbbf0825b If the phi node was used by an unreachable instruction that ends up using 
itself without going via a phi node then we could return false here in
spite of making a change.  Also, tweak the comment because this method
can (and always could) return true without deleting the original phi node.
For example, if the phi node was used by a read-only invoke instruction
which is used by another phi node phi2 which is only used by and only uses
the invoke, then phi2 would be deleted but not the invoke instruction and
not the original phi node.

Chris Lattner 5237febf0c a serious "compare CSE" issue that is nontrivial to get right, 
but which is responsible for us doing really bad things to 256.bzip2.

Duncan Sands 6dcd49bc2b Simplify RecursivelyDeleteDeadPHINode. The only functionality change 
should be that if the phi is used by a side-effect free instruction with
no uses then the phi and the instruction now get zapped (checked by the
unittest).

John McCall 701417a0ac Pseudo-revirtualize CallExpr::getSourceRange by making it follow the 
logic from CXXMemberCallExpr and by making it check for
CXXOperatorCallExpr in order to defer.  This is not really an awesome solution,
but I don't have a better idea.

NAKAMURA Takumi 860abd0f28 Target/X86/X86FastISel: [PR6275] Fix Win32's dllimport function with fastisel. 
"dllimport" function must not be GlobalVariable, but Function. It is enough to check with GlobalValue.

John McCall f2e9110a9f Rename test/CodeGenCXX/gnu-conditional-scalar-ext.cpp to conditional-gnu-ext.cpp 
for consistency with other tests (and to remove "scalar" from the name).

Cameron Zwarich 39314bdbc8 A lo/hi mul has higher latency than an imul r,ri, e.g. 5 cycles compared to 3 
on Core 2 and Nehalem, so the code we generate is better than GCC's here.

Chandler Carruth d05b352b0e Clean up the tests for warning about unused function results given the 
appropriate attribute. Add a bit more testing that finds a pretty bad
regression (since ~forever) in this warning. Fix it with a nice 2 line
change. =]

Cameron Zwarich 8731d0cc83 The signed version of our "magic number" computation for the integer approximation 
of a constant had a minor typo introduced when copying it from the book, which
caused it to favor negative approximations over positive approximations in many
cases. Positive approximations require fewer operations beyond the multiplication.

In the case of division by 3, we still generate code that is a single instruction
larger than GCC's code.

Chandler Carruth 468b5cbd40 Allow -Wformat to be enabled without -Wformat-security. GCC gates

Nick Lewycky 183c24c51b Make RecursivelyDeleteDeadPHINode delete a phi node that has no users and add a 
test for that. With this change, test/CodeGen/X86/codegen-dce.ll no longer finds
any instructions to DCE, so delete the test.

Also renamed J and JP to I and IP in RecursivelyDeleteDeadPHINode.

 2011-02-20 15:20:01 +00:00
Benjamin Kramer d5d7f37beb InstCombine: Add a bunch of combines of the form x | (y ^ z). 
We usually catch this kind of optimization through InstSimplify's distributive
magic, but or doesn't distribute over xor in general.

"A | ~(A | B) -> A | ~B" hits 24 times on gcc.c.

Nadav Rotem 25f2ac948b Fix 9267; Add vector zext support. 
The DAGCombiner folds the zext into complex load instructions. This patch
prevents this optimization on vectors since none of the supported targets
knows how to perform load+vector_zext in one instruction.
