[bug-mdk] Bug in the `sbpr' command of mixvm

[rrl]

Hi,

There's a problem with the command `sbpr' that set a conditional
breakpoint on register change.  For example, `sbpr I2' should set a
breakpoint when the value in rI2 changes but the breakpoint will be
set when the value of rI1 changes instead.  Here's a patch that fixes
the problem:
