2010-12-06Rename CXXExprWithTemporaries -> ExprWithCleanups; there's no theoreticalJohn McCall
reason this is limited to C++, and it's certainly not limited to temporaries. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120996 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-05Fix a bug in the emission of __real/__imag l-values on scalar operands.John McCall
Fix a bug in the emission of complex compound assignment l-values. Introduce a method to emit an expression whose value isn't relevant. Make that method evaluate its operand as an l-value if it is one. Fixes our volatile compliance in C++. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120931 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-04Silly special case: never load when dereferencing void*.John McCall
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120905 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-04Although we currently have explicit lvalue-to-rvalue conversions, they'reJohn McCall
not actually frequently used, because ImpCastExprToType only creates a node if the types differ. So explicitly create an ICE in the lvalue-to-rvalue conversion code in DefaultFunctionArrayLvalueConversion() as well as several other new places, and consistently deal with the consequences throughout the compiler. In addition, introduce a new cast kind for loading an ObjCProperty l-value, and make sure we emit those nodes whenever an ObjCProperty l-value appears that's not on the LHS of an assignment operator. This breaks a couple of rewriter tests, which I've x-failed until future development occurs on the rewriter. Ted Kremenek kindly contributed the analyzer workarounds in this patch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120890 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-16Simplify some complex emission and implement correct semantics forJohn McCall
assignment to volatiles in C. This in effect reverts some of mjs's work in and around r72572. Basically, the C++ standard is quite clear, except that it lies about volatile behavior approximating C's, whereas the C standard is almost actively misleading. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@119344 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-14Add a few more complex-related cast kinds that arise due to arbitraryJohn McCall
implicit conversions; the last batch was specific to promotions. I think this is the full set we need. I do think dividing the cast kinds into floating and integral is probably a good idea. Annotate a *lot* more C casts with useful cast kinds. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@119036 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-17Add a -ftrapv-handler= option which allows a handler to invoke instead of ↵David Chisnall

2010-09-15one piece of code is responsible for the lifetime of every aggregateJohn McCall
slot. The easiest way to do that was to bundle up the information we care about for aggregate slots into a new structure which demands that its creators at least consider the question. I could probably be convinced that the ObjC 'needs GC' bit should be rolled into this structure. Implement generalized copy elision. The main obstacle here is that IR-generation must be much more careful about making sure that exactly git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113962 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-23Abstract out everything having to do with member pointers into the ABIJohn McCall
class; they should just be completely opaque throughout IR gen now, although I haven't really audited that.

2010-08-22Experiment with using first-class aggregates to represent member functionJohn McCall
pointers. I find the resulting code to be substantially cleaner, and it makes it very easy to use the same APIs for data member pointers (which I have conscientiously avoided here), and it avoids a plethora of potential inefficiencies due to excessive memory copying, but we'll have to see if it actually works. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111776 91177308-0d34-0410-b5e6-96231b3b80d8
