- Subject: [commit] New function gdbarch_infi_fill
Hello,
The attached adds the new function gdbarch_info_fill. This new function
fills in un-initialized fields of the "info" structure using global
"set" variables and the "gdbarch" parameter.
committed,
Andrew
2003-11-09 Andrew Cagney <cagney@redhat.com>
* Makefile.in (arch-utils.o): Update dependencies.
* arch-utils.c: Include "osabi.h".
(gdbarch_info_fill): New function.
* arch-utils.h (gdbarch_info_fill): Declare.
* gdbarch.sh (gdbarch_update_p): Call "gdbarch_info_fill".
* gdbarch.c: Re-generate.
