Fix the ValueMap copy constructor.  The issue is that the map keys are value
handles with a pointer to the containing map.  When a map is copied, these
pointers need to be corrected to point to the new map.  If not, then consider
the case of a map M1 which maps a value V to something.  Create a copy M2 of
M1.  At this point there are two value handles on V, one representing V as a
key in M1, the other representing V as a key in M2.  But both value handles
point to M1 as the containing map.  Now delete V.  The value handles remove
themselves from their containing map (which destroys them), but only the first
value handle is successful: the second one cannot remove itself from M1 as
(once the first one has removed itself) there is nothing there to remove; it
is therefore not destroyed.  This causes an assertion failure "All references
to V were not removed?".

Jim Grosbach [Fri, 30 Jul 2010 02:41:01 +0000 (02:41 +0000)]
Many Thumb2 instructions can reference the full ARM register set (i.e.,
have 4 bits per register in the operand encoding), but have undefined
behavior when the operand value is 13 or 15 (SP and PC, respectively).
The trivial coalescer in linear scan sometimes will merge a copy from
SP into a subsequent instruction which uses the copy, and if that
instruction cannot legally reference SP, we get bad code such as:
  mls r0,r9,r0,sp
instead of:
  mov r2, sp
  mls r0, r9, r0, r2

This patch adds a new register class for use by Thumb2 that excludes
the problematic registers (SP and PC) and is used instead of GPR
for those operands which cannot legally reference PC or SP. The
trivial coalescer explicitly requires that the register class
of the destination for the COPY instruction contain the source
register for the COPY to be considered for coalescing. This prevents
errant instructions like that above.
