GDB computes structure byte offsets using a 32 bit integer. And, first it computes the offset in bits and then converts to bytes. The result is that any offset that if 512K bytes or larger overflows. This patch changes GDB to use LONGEST for such calculations. PR gdb/17520 Structure offset wrong when 1/4 GB or greater. * c-lang.h: Change all parameters, variables, and struct or union members used as struct or union fie3ld offsets from int to LONGEST. * c-valprint.c: Likewise. * cp-abi.c: Likewise. * cp-abi.h: Likewise. * cp-valprint.c: Likewise. * d-valprint.c: Likewise. * dwarf2loc.c: Likewise. * eval.c: Likewise. * extension-priv.h: Likewise. * extension.c: Likewise. * extension.h: Likewise. * findvar.c: Likewise. * gdbtypes.h: Likewise. * gnu-v2-abi.c: Likewise. * gnu-v3-abi.c: Likewise. * go-valprint.c: Likewise. * guile/guile-internal.h: Likewise. * guile/scm-pretty-print.c: Likewise. * jv-valprint.c Likewise. * opencl-lang.c: Likewise. * p-lang.h: Likewise. * python/py-prettyprint.c: Likewise. * python/python-internal.h: Likewise. * spu-tdep.c: Likewise. * typeprint.c: Likewise. * valarith.c: Likewise. * valops.c: Likewise. * valprint.c: Likewise. * valprint.h: Likewise. * value.c: Likewise. * value.h: Likewise. * p-valprint.c: Likewise. * c-typeprint.c (c_type_print_base): When printing offset, use plongest, not %d. * gdbtypes.c (recursive_dump_type): Ditto.
