Re: Mingw GDB build fails for M16C target

[Mahesh Basavaraj Shavari]

Hi,

I have now built the MinGW gdb successfully but without simulator;
using option '--disable-sim'.

There is still following issue with simulator building:

>/home/mahesh/GDB/gdb-6.8/gdb-6.8.50.20090327/sim/m32c/mem.c:29:24:
>sys/select.h: No such file or directory
>/home/mahesh/GDB/gdb-6.8/gdb-6.8.50.20090327/sim/m32c/mem.c:30:21:
>termios.h: No such file or directory
>/home/mahesh/GDB/gdb-6.8/gdb-6.8.50.20090327/sim/m32c/mem.c: In function
>`stdin_ready':
>/home/mahesh/GDB/gdb-6.8/gdb-6.8.50.20090327/sim/m32c/mem.c:383: error:
>`fd_set' undeclared (first use in this function)

Any help would be highly appreciated.
Thank you.

Best regards,
Mahesh Shavari

Mahesh,

Please try the patch below and let me know if it works for you.

Jim,

It appears to me that comment, "Oddly, the gdb/sim interface uses host
signal numbers...", isn't true.  My patch deletes this comment in
addition to using TARGET_SIGNAL_foo instead of SIGfoo.  If you look at
remote-sim.c, you'll see that `enum target_signal' (which defines the
various TARGET_SIGNAL_foo constants) is used throughout the file.

Okay to apply?

Kevin

	* m32c/gdb-if.c (m32c_signal_to_host): Rename to
	m32c_signal_to_target.  Change signal return values from SIGILL,
	SIGTRAP, SIGSEGV, etc. to TARGET_SIGNAL_ILL, TARGET_SIGNAL_TRAP,
	TARGET_SIGNAL_SEGV, etc.  Fix all callers.
