This JIT buster test checks to see if a JIT doing register allocation
|
|
on a machine with a callees saves ABI for non-volatile registers can
|
|
get the exception handling correct. Intel and PowerPC are both such
|
|
machines. The problem is restoring the correct values of i and j in
|
|
the catch block. If i and j are never put into registers, then the
|
|
JIT won't have a problem with correctness because the catch block
|
|
will load the correct values from memory. If the JIT puts i and j
|
|
into registers, then restoring their correct values at the catch
|
|
block gets a little bit tougher.
