I don't have a small testcase for this.

__alignof__ operator, make sure to take into account the packed alignment
of the struct/union/class itself. Matches GCC's behavior and fixes PR6362.

More fixes. Don't try to emit a virtual base vtable if the virtual base in question is a primary virtual base of some other base.

llvm-svn: 96881

Always emit vcall offset for the primary base, not only if it's virtual. Remove a debug printf, and add the test case that now passes.

llvm-svn: 96880

Simplify the vcall offset calculation and make it give the correct answers :) My test case now has the right values but in the wrong order.

llvm-svn: 96877

llvm-svn: 96875

More work on vcall offsets. We now emit the right number of vcall offsets in my local test case, but not the right values.

don't alis it in the MMX .td file with a different width,
split into two X86ISD opcodes.  This fixes an x86 testcase.

VBR encoding for the insanity being perpetrated by the spu backend. 

llvm-svn: 96843

1) emit base destructors as aliases to their unique base class destructors
under some careful conditions.  This is enabled for the same targets that can
support complete-to-base aliases, i.e. not darwin.

2) Emit non-variadic complete constructors for classes with no virtual bases
as calls to the base constructor.  This is enabled on all targets and in
theory can trigger in situations that the alias optimization can't (mostly
involving virtual bases, mostly not yet supported).

These are bundled together because I didn't think it worthwhile to split them,
not because they really need to be.

C++98/03 and C++0x, since the '0x semantics break valid C++98/03
code. This new mess is tracked by core issue 399, which is still
unresolved.

Fixes PR6358 and PR6359.

ridiculously ginormous patterns and need more than one byte
of displacement for encodings.  This fixes CellSPU/fdiv.ll.
SPU is still doing something else ridiculous though.

Instcombine constant folding can normalize gep with negative index to index with large offset. When instcombine objsize checking transformation sees these geps where the offset seemingly point out of bound, it should just return "i don't know" rather than asserting.

well as the operands produced when the pattern is matched.  This
allows CheckSame to work correctly when matching replicated 
names involving ComplexPatterns.  This fixes a bunch of MSP430 
failures, we're down to 13 failures, two of which are
due to a sched bug.

126.gcc nightly tests. These failures uncovered latent bugs that machine DCE
could remove one half of a stack adjust down/up pair, causing PEI to assert.
This update fixes that, and the tests now pass.
