df0fe27b66 Fixup the rest of the trivial cases of the codegen of volatile. If 
any body can spot codegen bugs with volatile, or knows of any in the
bug database, let me know.

c63428b192 Fixup codegen for __block int i; i += rhs();. Should also slightly 
improve codegen in some cases.

aed08f9929 Fixup blocks codegen for { __block i; i = rhs(); }, we want the rhs 
evaluated first.  This can also improve codegen just a bit as we might
have another register to play with for the evaluation of the rhs.

ef2ffbc390 Fix pointer addressing and array subscripting of Objective-C interface 
types.
 - I broke this in the switch to representing interfaces with opaque
   types.

 - <rdar://problem/6822660> clang crashes on subscript of interface in
   32-bit mode

562d68e8db Pointer width on targets like PIC16 is 16-bit, while the valid index size to GEP is only 32 or 64. So promote index to 32 in such cases.

d3e3885f2d Remove -ftrapu. 
llvm-svn: 68330
 2009-04-02 18:15:54 +00:00
Mike Stump
40968598c7 Fixup -ftrapv to be more gcc compatible. -ftrapu (for want of a 
better name) is the option that SmallTalk can use to intercept all
overflows, including unsigned.  I added some testcases so we don't
break anything.

Also included is another patch from David for += and friends.

8b7b1b1aee Change compound assignment operators to keep track of both the promoted 
LHS type and the computation result type; this encodes information into 
the AST which is otherwise non-obvious.  Fix Sema to always come up with the 
right answer for both of these types.  Fix IRGen and the analyzer to 
account for these changes.  This fixes PR2601.  The approach is inspired 
by PR2601 comment 2.

Note that this changes real *= complex in CodeGen from a silent 
miscompilation to an explicit error.

I'm not really sure that the analyzer changes are correct, or how to 
test them... someone more familiar with the analyzer should check those 
changes.

a374b68b5a Back out the patch in r66302, and re-fix it properly. We assume for 
performance that the type of the returned llvm::Value for an expression 
matches the converted type of the clang::Expr; mismatches will cause all
sorts of errors and silent miscompilations.

988a16b9b8 Change the AST generated for offsetof a bit so that it looks like a 
normal expression, and change Evaluate and IRGen to evaluate it like a 
normal expression.  This simplifies the code significantly, and fixes 
PR3396.

d7e7b8e411 first wave of fixes for @encode sema support. This is part of PR3648. 
The big difference here is that (like string literal) @encode has 
array type, not pointer type.

ab3afd8f2d Initial codegen for block literals. This is a work in progress. I've 
tried to put FIXMEs on the most important things to fix up.  Lots left
to do including more codegen, more documentation and cleaning code and
style cleanups.

0202cb406e Introduce a new expression node, ImplicitValueInitExpr, that 
represents an implicit value-initialization of a subobject of a
particular type. This replaces the (ab)use of CXXZeroValueInitExpr
within initializer lists for the "holes" that occur due to the use of
C99 designated initializers.

The new test case is currently XFAIL'd, because CodeGen's
ConstExprEmitter (in lib/CodeGen/CGExprConstant.cpp) needs to be
taught to value-initialize when it sees ImplicitValueInitExprs.
