046afdb50b The bits in the cmode field of 32-bit VMOV immediate instructions all depend 
of the value of the immediate.

which get the same line, and this confuses debug info.

b5611a6230 In inline asm treat indirect 'X' constraint as 'm'.

than asserting which it was doing before.  PR 7528.

6382d2cadd Add an assertion to make PR7542 fail consistently. 
LiveInterval::overlapsFrom dereferences end() if it is called on an empty
interval.

It would be reasonable to just return false - an empty interval doesn't overlap
anything, but I want to know who is doing it first.

218977b53e Extend the r107852 optimization which turns some fp compare to code sequence using only i32 operations. It now optimize some f64 compares when fp compare is exceptionally slow (e.g. cortex-a8). It also catches comparison against 0.0.

d0d3ccc827 Handle the case of a tail recursion in which the tail call is followed 
by a return that returns a constant, while elsewhere in the function
another return instruction returns a different constant.  This is a
special case of accumulator recursion, so just generalize the existing
logic a bit.

63d024fc9a rotate CallInst operands 
with this commit the callee moves to the end of
the operand array (from the start) and the call
arguments now start at index 0 (formerly 1)

this ordering is now consistent with InvokeInst

this commit only flips the switch,
functionally it is equivalent to
r101465

I intend to commit several cleanups after a few
days of soak period

9fac4159dd Don't add memory operands to storeRegToStackSlot / loadRegFromStackSlot results, 
they already have one.

slot load above a store to the same slot.
