Eli Friedman cd2e0cd297 Update for CMakeLists; untested, so tell me if there are issues. 
llvm-svn: 72360
 2009-05-24 09:13:13 +00:00
Eli Friedman a4e1675dac Remove checks of getTypeAction from LegalizeOp; we already assert that 
all results and all operands are legal, so this change shouldn't affect 
behavior at all.

Eli Friedman 5e0d150689 Disable type legalization in LegalizeDAG. 
This leaves around 4000 lines of dead code; I'll clean that up 
in subsequent commits.

Eli Friedman 7badee92ad Fix a bug in the expansion of EXTRACT_SUBVECTOR in 
ExpandExtractFromVectorThroughStack.

llvm-svn: 72351
 2009-05-23 23:03:28 +00:00
Eli Friedman 2199ed399f Make the X86 backend mark EXTRACT_SUBVECTOR as Expand, at least for the 
moment.

llvm-svn: 72350
 2009-05-23 22:44:52 +00:00
Eli Friedman 40afdb63ec Add a proper implementation of EXTRACT_SUBVECTOR legalization that 
doesn't split legal vector operands.  This is necessary because the 
type legalization (and therefore, vector splitting) code will be going 
away soon.

Mike Stump 5e9e61b8d2 Track volatile aggregate copies better. I'm hoping someone else will decide 
how to get the backend to know that the operation is volatile.

is still ignored.

Torok Edwin be6a9a151a Fix PR4254. 
The DAGCombiner created a negative shiftamount, stored in an
unsigned variable. Later the optimizer eliminated the shift entirely as being
undefined.
Example: (srl (shl X, 56) 48). ShiftAmt is 4294967288.
Fix it by checking that the shiftamount is positive, and storing in a signed
variable.

Torok Edwin 7996339dd8 available_externall linkage is not local, this was confusing the codegenerator, 
and it wasn't generating calls through @PLT for these functions.
hasLocalLinkage() is now false for available_externally,
I attempted to fix the inliner and dce to handle available_externally properly.
It passed make check.

Eli Friedman 53a71147ba Fix test to account for legalization changes; I think this ends up 
running an extra DAGCombine pass which improves the code a bit.

Eli Friedman da90dd6d72 Add a new step to legalization to legalize vector math operations. This 
will allow simplifying LegalizeDAG to eliminate type legalization.  (I 
have a patch to do that, but it's not quite finished; I'll commit it 
once it's finished and I've fixed any review comments for this patch.)  
See the comment at the beginning of 
lib/CodeGen/SelectionDAG/LegalizeVectorOps.cpp for more details on the
motivation for this patch.

Eli Friedman dfe4f25355 Make the x86 backend custom-lower UINT_TO_FP and FP_TO_UINT on 32-bit 
systems instead of attempting to promote them to a 64-bit SINT_TO_FP or 
FP_TO_SINT.  This is in preparation for removing the type legalization 
code from LegalizeDAG: once type legalization is gone from LegalizeDAG, 
it won't be able to handle the i64 operand/result correctly.

This isn't quite ideal, but I don't think any other operation for any 
target ends up in this situation, so treating this case specially seems 
reasonable.

Douglas Gregor 4a9f481db9 Template instantiation for qualified declaration reference 
expressions. We are now missing template instantiation logic for only
three classes of expressions:
  - Blocks-related expressions (BlockExpr, BlockDeclRefExpr)
  - C++ default argument expressions
  - Objective-C expressions

Additionally, our handling of DeclRefExpr is still quite poor, since
it cannot handle references to many kinds of declarations.

As part of this change, converted the TemplateExprInstantiator to use
iteration through all of the expressions via clang/AST/StmtNodes.def,
ensuring that we don't forget to add template instantiation logic for
any new expression node kinds.

Ted Kremenek ed28b6d028 Modify begin()/end() for AsmStmt iterators to handle the case when Exprs.empty() 
is true. Because of recent changes to llvm::SmallVector, using these iterators
when Exprs was empty would cause an assertion failure.

This fixes: PR 4245.
