12 years agoIt's possible for two types, which are isomorphic, to be added to the
Bill Wendling [Fri, 23 Mar 2012 23:17:38 +0000 (23:17 +0000)]
It's possible for two types, which are isomorphic, to be added to the
destination module, but one of them isn't used in the destination module. If
another module comes along and the uses the unused type, there could be type
conflicts when the modules are finally linked together. (This happened when
building LLVM.)

The test that was reduced is:

Module A:

%Z = type { %A }
%A = type { %B.1, [7 x x86_fp80] }
%B.1 = type { %C }
%C = type { i8* }

declare void @func_x(%C*, i64, i64)
declare void @func_z(%Z* nocapture)

Module B:

%B = type { %C.1 }
%C.1 = type { i8* }
%A.2 = type { %B.3, [5 x x86_fp80] }
%B.3 = type { %C.1 }

define void @func_z() {
  %x = alloca %A.2, align 16
  %y = getelementptr inbounds %A.2* %x, i64 0, i32 0, i32 0
  call void @func_x(%C.1* %y, i64 37, i64 927) nounwind
  ret void
}

declare void @func_x(%C.1*, i64, i64)
declare void @func_y(%B* nocapture)

(Unfortunately, this test doesn't fail under llvm-link, only during an LTO
linking.) The '%C' and '%C.1' clash. The destination module gets the '%C'
declaration. When merging Module B, it looks at the '%C.1' subtype of the '%B'
structure. It adds that in, because that's cool. And when '%B.3' is processed,
it uses the '%C.1'. But the '%B' has used '%C' and we prefer to use '%C'. So the
'@func_x' type is changed to 'void (%C*, i64, i64)', but the type of '%x' in
'@func_z' remains '%A.2'. The GEP resolves to a '%C.1', which conflicts with the
'@func_x' signature.

We can resolve this situation by making sure that the type is used in the
destination before saying that it should be used in the module being merged in.

With this fix, LLVM and Clang both compile under LTO.

12 years agoRuntimeDyldMachO has the ability to keep track of
Sean Callanan [Tue, 20 Mar 2012 22:25:39 +0000 (22:25 +0000)]
RuntimeDyldMachO has the ability to keep track of
relocations (i.e., pieces of data whose addresses
are referred to elsewhere in the binary image) and
update the references when the section containing
the relocations moves.  The way this works is that
there is a map from section IDs to lists of
relocations.

Because the relocations are associated with the
section containing the data being referred to, they
are updated only when the target moves.  However,
many data references are relative and also depend
on the location of the referrer.

To solve this problem, I introduced a new data
structure, Referrer, which simply contains the
section being referred to and the index of the
relocation in that section.  These referrers are
associated with the source containing the
reference that needs to be updated, so now
regardless of which end of the relocation moves,
the relocation will now be updated correctly.

Require a base pointer for stack realignment when SP may vary dynamically.

ARMBaseRegisterInfo::canRealignStack was checking for variable-sized objects
but not for stack adjustments around calls.  Use hasReservedCallFrame() to
check for both.  The hasBasePointer function was already correctly checking
both conditions, so the effect of this was that a base pointer would be used
without checking whether the base pointer register could be reserved. I don't
