...node unless
aggreagte accesses are supported.
To distinct unions from other types we can have a special group for
them. Alternatively, we can use type identification nodes, see below.
For aggregate accesses:
The comment in TypeBasedAliasAnalysis.cpp suggests:
// TODO: We need to check if AccessType of TagA encloses AccessType of
// TagB to support aggregate AccessType. If yes, return true.
Consider these two accesses:
struct A { int i; };
struct B { struct A a; } *b;
struct X { int i; } *x;
b->a
x->i
Following the rule in the comment, the accesses are al...

TBAA metadata
...() calls createTBAAStructTagNode() to create the access tag, but it does not pass the IsConstant parameter.
/// \brief Return metadata for a TBAA tag node with the given
/// base type, access type and offset relative to the base type.
MDNode *createTBAAStructTagNode(MDNode *BaseType, MDNode *AccessType,
uint64_t Offset, bool IsConstant = false);
So my questions are:
- Is there any reason IsConstant is never set ?
- Would it be valid to set this information according to the const-qualifier of the data accessed, maybe by getting it from Qual...

SOAP client not seeing all of my AWS service methods
Hi all,
Ruby 1.8.4
Rails 1.1.2
I''m a newb when it comes to SOAP, but I thought I''d give it a shot. I
have several web services defined. However, when I try to connect with
a SOAP client it seems the client is only picking up one of the
services, called Hardware.

Sadly, this is where this becomes "unlikely to want to use to replace
TBAA", at least for me. It may still be a thing we want anyway.
This scheme is really an encoding of C/C++ TBAA info so it can be read by
LLVM and requires

[LLVMdev] alias set collapse and LICM
I'm current facing an issue related to AliasSetTracker/LICM: the
transitive closure of the alias sets is materially more conservative
than individual aliasing queries and this conservatism leads to
generally worse optimization in LICM.
For instance, consider this module:
declare i32 @only_reads() readonly
declare void @escape(i32*, i32*, i32*)
define void @f(i32 %count) {
entry:

[LLVMdev] PROPOSAL: struct-access-path aware TBAA (new version)
Hello,
After discussions with Daniel, Dan and others, here is an updated proposal for struct-access-path aware TBAA.
Given an example
struct A {
int x;
int y;
};
struct B {
A a;
int z;
};
struct C {
B b1;
B b2;
int *p;
};
struct D {
C c;
};
The purpose of struct-path-aware TBAA is to say
"C::b1.a" will alias with "B::a.x", "C::b1.a" will alias with
