ICE with gcc 3.4

ICE with gcc 3.4

[Nitin Yewale]

Hi,
	I would like to add following test case in dejagnu test suite under "gcc/testsuite/gcc.c-torture/compile" directory.

	Following program was giving ICE with "h8300-elf-gcc -ms -mn -c kp_ice.cpp" command line.

	H8300-elf toolchain is built by using gcc 3.4.

/**************** START of kp_ice.cpp**************************/
void f(void) __attribute__((interrupt_handler));
void g(void) { }
void f(void) { g(); }
/**************** End of kp_ice.cpp**************************/

Regards,

Mailing it to gcc-bugs will not accomplish this.  Patches need to be 
sent to gcc-patches.  This also needs to be sent as a patch with a 
ChangeLog entry.

Also, you need a bit more work on the testcase.  It needs to fit into 
the testsuite.  This is an h8300 only testcase, so it needs to be marked 
as such.  See examples already in the testsuite, for instance, 
gcc/testsuite/gcc.dg/h8300-stack-1.c.  You also need to indicate where 
this is a compile only or compile and run testcase, and you need to put 
in any special compiler options, etc.  There are dg-* commands for all 
of this stuff.

Try using grep.  There are at least two others in the gcc.dg directory,
and maybe some others in other directories.

There is no standard naming scheme.  Sometimes they are named after the
date that they are submitted.  Sometimes they are named after the
feature that is broken.  See for instance the gcc.dg/attr-* testcases.

Hi Jim,
	
	Thank you very much for valuable suggestions. 
	
	I have a couple of crucial test cases for H8 and SH targets and while posting on gcc-patches mailing list and I will make sure that all test cases are in proper format.

	I have posted the test case on gcc-patches mailing list http://gcc.gnu.org/ml/gcc-patches/2004-06/msg01871.html

	I am able to locate only one test case for h8300 target [h8300-stack-1.c].
 
	Please suggest the standard naming convention I should use for further test cases.
Thanks and Regards,
