Daniel Dunbar e017ecc9e2 Remove ';' after method definition. Noticed by clang++, which one would think 
would have a higher respect for its own code. This is getting old, is this
warning really adding value?

Anders Carlsson b396f43520 It's perfectly fine to see UserDefinedConversion casts when emitting scalar expressions.

Mike Stump e8c3b3eca4 Switch codegen for -fcatch-undefined-bahavior over to __builtin_trap 
instead of abort to improve codesize and codegen.

for logical not.

Eli Friedman d70bbfd7d8 Support unary type traits in a scalar context. Not that I've actually seen 
this construct, but might as well for completeness.

Fariborz Jahanian 531c16f9fb Code gen for ObjCIsaExpr AST used as lvalue. 
(fixes radar 7457534).

 2009-11-28 19:45:26 +00:00
Eli Friedman e96f1d3b2f More work on ScalarExprEmitter::EmitCastExpr: for every cast kind, either 
implement it explicitly or assert that it doesn't make sense for a scalar.
This caught a couple interesting issues: one, CK_BaseToDerivedMemberPointer
casts were getting silently miscompiled, and two, Sema was constructing some
strange implicit casts of type CK_UserDefinedConversion.

The change in SemaExprCXX makes sure the cast kinds are getting set correctly.

Eli Friedman 0dfc6804ff Cleanup for ScalarExprEmitter::EmitCastExpr; no functional changes.

Eli Friedman cb422f1dbe Use the more general Evaluate infrastructure for folding constant DeclRefs 
instead of checking explicitly for an EnumConstantDecl.  This folds references
to constant integer VarDecls, which has two benefits:

1. Slightly smaller emitted code from emitting a constant instead of a load,
and skipping emitting some constant globals.
2. Some code forgets to define static constant member variables; emitting a
load instead of the value in that case leads to a link error. (Such programs
are technically not well-formed, but in practice build with g++.)

Anders Carlsson b9f96a3286 We always need to emit the base expression of a member expression, even when the member decl refers to an enum. Thanks to Eli for pointing this out! 
llvm-svn: 89775
 2009-11-24 16:57:33 +00:00
Anders Carlsson f2e4f72f03 Don't try to treat an enum constant as an lvalue.

llvm-svn: 89201
 2009-11-18 09:41:26 +00:00

llvm-svn: 86256
 2009-11-06 17:38:18 +00:00
Mike Stump 53f9ded62b Refine volatile handling, specifically, we must have the canonical 
type to look at the volatile specifier.  I found these all from just
hand auditing the code.

Anders Carlsson 4b08db7a62 Add CGException.cpp, to be used for exception related code generation. 
llvm-svn: 85560
 2009-10-30 01:42:31 +00:00
Chris Lattner 6c4d255bf3 Implement clang support for indirect branch and address of label 
using the new LLVM support for this.  This is temporarily hiding
behind horrible and ugly #ifdefs until the time when the optimizer
is stable (hopefully a week or so).  Until then, lets make it "opt in" :)

Nate Begeman 19351639fb Support IRgen of OpenCL vector initializers, ensuring the resulting IR is in a 
form that LLVM code generators can turn into efficient code.  For example,
int4 a, b, c;
a = (int4)(b.yzw, a.x)

llvm-svn: 84434

llvm-svn: 84423
 2009-10-18 18:12:03 +00:00
Chris Lattner 671fec8727 Fix PR5211: codegen shouldn't assume that the result of ||/&& is int 
anymore.  In C++ it is bool.

John McCall 8ccfcb51ee Refactor the representation of qualifiers to bring ExtQualType out of the 
Type hierarchy.  Demote 'volatile' to extended-qualifier status.  Audit our
use of qualifiers and fix a few places that weren't dealing with qualifiers
quite right;  many more remain.

 2009-09-22 22:00:46 +00:00
John McCall 9dd450bb78 Change all the Type::getAsFoo() methods to specializations of Type::getAs(). 
Several of the existing methods were identical to their respective
specializations, and so have been removed entirely.  Several more 'leaf'
optimizations were introduced.

The getAsFoo() methods which imposed extra conditions, like
getAsObjCInterfacePointerType(), have been left in place.
