/* With enough constants, constant numbers emitted for e.g. GETPROP will no
|
|
* longer fit into the short 9-bit arguments and will cause problems.
|
|
* In the worst case a constant reference becomes a register reference
|
|
* because the reg/const indicator bit will be flipped; this further
|
|
* causes valgrind gripes.
|
|
*
|
|
* This needs to be fixed in the compiler so that it will croak when it
|
|
* attempts to emit invalid code. Also constants above the 9-bit addressable
|
|
* range need to be coerced into temp registers with LDCONST.
|
|
*
|
|
* This test case illustrates the current problem: execution fails and
|
|
* there are valgrind errors for invalid reads.
