py-inferior.exp: Make sure local var is allocated on the stack.
The testcase, at some point, is trying to change the contents
of a string that was defined as follow:
char *str = "hello, testsuite";
The problem is that the string is constant, and str is never used
to change the contents of the string in the program, so the compiler
is free to allocate it in a read-only section. This is what happens
on x86-windows, for instance.
As a result, trying to change the contents of the string during
the `python gdb.inferiors()[0].write_memory (addr, str)' results
in the following error:
(gdb) python gdb.inferiors()[0].write_memory (addr, str)

Traceback (most recent call last):
File "<string>", line 1, in <module>

array rather than a pointer.

The BF537 family glues a bunch of peripherals into single interrupt lines

sim: bfin: push SIC mappings to device tree
The machs.c file is the best place for holding cpu-specific details, so
restructure the way the SIC manages its ports to do just that. Now the
SIC's have a standard set of input pins and the different line routing
from peripherals is kept in the device tree only. This better models
the hardware where the SIC doesn't care about the exact peripheral that
is sending it stuff, just which input pin it gets it on.
