PR binutils/17512 * coffdump.c (dump_coff_section): Check for a symbol being available before printing its name. (main): Check the return value from coff_grok. * coffgrok.c: Reformat and tidy. Add range checks to most functions. (coff_grok): Return NULL if the input bfd is not in a COFF format. * coffgrok.h: Reformat and tidy. (struct coff_section): Change the nrelocs field to unsigned. * srconv.c (main): Check the return value from coff_grok. * coff-i860.c (CALC_ADDEND): Always set an addend value. * tekhex.c (getvalue): Add an end pointer parameter. Use it to avoid reading off the end of the buffer. (getsym): Likewise. (first_phase): Likewise. (pass_over): Pass an end pointer to the invoked function.
