Rounding differences causes tests to fail on Linux.

comparisons sign-extended to a different bitwidth than the
comparison operands.

Another sibcall bug. If caller and callee calling conventions differ, then it's only safe to do a tail call if the results are returned in the same way.

MachineFunction::DefaultDebugLoc.  We now use the same technique as
DwarfDebug::beginFunction to find the starting line number for a
function.

of different register classes. e.g.

  %reg1048:3<def> = EXTRACT_SUBREG %RAX<kill>, 3

Where %reg1048 is a GR32 register. This is not impossible to handle, but it is
pretty hard and very rare.

This should unbreak the dragonegg builder.

Replace r102368 with code that's less fragile. This creates DBG_VALUE instructions for function arguments early and insert them after instruction selection is done.

alignment of globals to the preferred alignment, but only when
there is no section specified on the global (by far the common

While lowering dbg_declare, emit DBG_VALUE machine instruction if alloca matching llvm.dbg.declare intrinsic is missing.

update them. Computing kill flags is notoriously difficult, and the coalescer
would get it wrong sometimes, and it would completely skip physical registers.

Now we simply remove kill flags based on the live intervals after coalescing.
This is a few percent slower, but now we get correct kill flags for physical
registers after coalescing.

This instruction would crash the pass:
