Hi
I think the command line arguments for the lm32 simulator
are not getting parsed the same for "run" as when you do
"tar sim" in gdb. Executables work with gdb that don't
with run.
lm32-rtems4.12-run --hw-file lm32_evr.conf \
--memory-region 0x08000000,0x4000000 ticker.exe
In gdb, the tar sim command is:
tar sim --hw-file lm32_evr.conf --memory-region 0x08000000,0x4000000
lm32_evr.conf is
/lm32cpu
/lm32uart/reg 0x80006000 0x100
/lm32uart > int int0 /lm32cpu
/lm32timer/reg 0x80002000 0x80
/lm32timer > int int1 /lm32cpu
Any ideas what's broken or where I should look?
I can compress an executable if someone wants to take a shot
at it.

wtf is "tar" ? hmm, guess it's short for "target sim" ...

the arg parsing codepaths are the same -- see sim/lm32/sim-if.c and
the sim_open function. gdb & the run frontend both call that.

It looks like something has changed. With gdb-7.11 and the
sparc-rtems4.11 target I am seeing:
$ /opt/work/rtems/4.12/bin/sparc-rtems4.12-run
./sparc-rtems4.12/c/erc32/testsuites/samples/ticker/ticker.exe
SIS - SPARC instruction simulator 2.7.5, copyright Jiri Gaisler 1995

sis> quit
With gdb-7.9 it use to just run the executable. GDB works.
