[Bug c/18898] New: [SH target], internal compiler error (ICE): for given code if using #pragma interrupt

["prafullat at kpitcummins dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Hi,

Sh-XXX-gcc gives ICE (internal compiler error) for subroutines 
with #pragma interrupt attribute when the size of variable or 
variables in the routing exceed 256 bytes.
GCC version: 3.4 and later.

Following is the simple test case for it. 

Test case:
///////////////////////////
//bug.c
#pragma interrupt
int foo (void)
{
#if ERROR
	char cName[257];
#else
	char cName[256];
#endif
	return 1;
}
/*
sh-XXX-gcc  -c -DERROR bug.c gives ICE
sh-XXX-gcc  -c  bug.c         no    ICE
*/
///////////////////////////
bug.c: In function `foo':
bug.c:10: internal compiler error: in output_stack_adjust, at 
config/sh/sh.c:4741 Please submit a full bug report, with 
preprocessed source if appropriate. See 
<URL:http://gcc.gnu.org/bugs.html> for instructions.
