that's a very interesting idea. It
Hi Dale, on my machine (x86-32, linux) LLVM considers long double to
have a size of 10 bytes and an alignment of 4 bytes. GCC gives it a
size of 12 bytes and an alignment of 4 bytes (of course only the first
80 bits (10 bytes) are actually used - the rest is padding).
I can see several problems
are spaced the same then I am happy. That said, the
meanings of type size etc should probably be well documented somewhere,
especially the fact that successive array elements may be space more
than the size apart.
Best wishes,
Duncan.

Hi Chris, this sounds like a big improvement! Where did you find the time

LegalizeDAG.cpp. It will remove all the code related to promotion and

Fix some typos. Call getTypeToTransformTo rather than
getTypeToExpandTo. The difference is that
getTypeToExpandTo gives the final result of expansion
(eg: i128 -
+SDOperand DAGTypeLegalizer::PromoteResult_TRUNCATE(SDNode *N) {
+ MVT::ValueType NVT = TLI.getTypeToTransformTo(N-getValueType(0));
+ switch (getTypeAction(N-getOperand(0).getValueType())) {
Presumably this switch is redundant, because it must be Promote,
and you just didn't get
Hi Devang,
// float foo(int w, float A[][w], int g) { return A[g][0]; }
ArrayAddr = BitCastToType(ArrayAddr, PointerType::get(Type::Int8Ty));

- TypeSize = CastToUIntType(TypeSize, IntPtrTy);

Hi Chris,
By the way the logic supposes that the result of any node is an
operand for
some other node. Is at least one result always used?
Nope, nodes are allowed to be unreachable/dead. What part assumes
that they are used?
I thought I had spotted a problem, but I can't find it

Return Expand from getOperationAction for all extended

It is not clear if this is correct for other operations.
On the other hand, for the various load/store actions

Hi Bill,
When ObjC is using SJLJ exceptions, don't create an unwind basic block
is this to avoid calling unwind resume? Do SJLJ exceptions actually
work with ObjC - I thought LLVM support was needed for sjlj exceptions
(I only looked at 4.2 though).
Thanks,
Duncan.
Hi Devang,
Do not raise free() call that is called through invoke instruction.
why not? As far as I know free cannot raise an exception, and we
don't support trapping exceptions for the moment.
Ciao,
Duncan.

Thanks Bill, the patch looks fine. This needs a testcase and needs
to be applied to 4.2 if it has the same problem,
Will do.
In 4.2 the unwind-resume function is configurable. For objc with SJLJ
exceptions it should be _Unwind_SjLj_Resume. If this is not correct for
objc, this can be
