This file is part of GDB.
Make writing to files work properly. (Fixes to BFD are also needed.) * core.c (core_open): Open file ourselves, read or r/w, depending on write_files. Use bfd_fdopenr. * gdbcore.h (write_files): New variable. * exec.c (write_files): Define variable, add set&show for it. (exec_file_command): Use write_files to open for read or r/write. Make shared library reading happen automatically. These changes are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>. * inferior.h (stop_soon_quietly): Add to exported variables. * infrun.c (child_create_inferior): call solib hook, if defined. (child_attach): call solib hook, if defined. * solib.c: Include inferior.h. Add from_tty to so_list as kludge. (find_solib): Use lookup_misc_func rather than hand-rolled. (symbol_add_stub): New stub for catch_errors. (solib_add): Avoid output if !from_tty. Catch errors rather than just calling symbol_file_add and bombing. (solib_create_inferior_hook): Interface with the target process to let it read and alloc shared libs, then figure out what it did. * core.c (validate_files): Fix typo, soften warning. (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.) * utils.c (fputs_demangled): Avoid duplicate printing if demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.) * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing. (Fix from pierre@la.tce.com (Pierre Willard).) * main.c (catch_errors): Change argument to a char * from an int, since a char * can point to a struct full of glop, but an int is not guaranteed to be able to hold a pointer. * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status, breakpoint_re_set_one, breakpoint_re_set): Adapt. * core.c (core_open, solib_add_stub): Adapt. * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
