[PATCH] Fix for PR60080

Fri, 07 Feb 2014 03:07:40 -0800 

Hi,

there has been a ICE on solaris 9 and 10 when dumping ASM_INPUT objects
without valid source loation at print-rtl.c.

print_rtx did not check for this, and tried to print NULL with printf format %s.
This happens to be handled by glibc's printf to print "(null)" but not on 
solaris.

Attached is my proposed patch for this: Firstly attaching the source location to
ASM_INPUT objects, that should not hurt, and secondly check for
UNKNOWN_LOCATION in print-rtl.c for ASM_INPUT and ASM_OPERANDS.

Boot-Strapped and Regression-tested on X86_64-linux-gnu.


Thanks
Bernd.
