From: Jim Wilson Date: Fri, 6 Oct 1995 19:06:13 +0000 (+0000) Subject: Changes to make the simulator work again. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=abf6a9dc4ebf206e0e9d619a1e2a700a60d068ff;p=binutils-gdb.git Changes to make the simulator work again. * callback.c (fdbad): Fix typo in comment. (os_close, os_isatty, os_lseek, os_read, os_write): Use if statements rather than || to get correct return value. (os_write_stdout): Pass missing first argument to os_write. * remote-sim.c: Include callback.h. (_initialize_remote_sim): Call sim_set_callbacks and then initialize the callbacks. --- diff --git a/gdb/ChangeLog b/gdb/ChangeLog index ddfa05f6c0a..035e5179d80 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,13 @@ +Fri Oct 6 11:56:49 1995 Jim Wilson + + * callback.c (fdbad): Fix typo in comment. + (os_close, os_isatty, os_lseek, os_read, os_write): Use if statements + rather than || to get correct return value. + (os_write_stdout): Pass missing first argument to os_write. + * remote-sim.c: Include callback.h. + (_initialize_remote_sim): Call sim_set_callbacks and then initialize + the callbacks. + Thu Oct 5 17:28:09 1995 Per Bothner * values.c allocate_repeat_value): Allocate an array type, and diff --git a/gdb/callback.c b/gdb/callback.c index b878f770e95..d59ecdabd7a 100644 --- a/gdb/callback.c +++ b/gdb/callback.c @@ -56,7 +56,7 @@ wrap (p, val) return val; } -/* Make sure the FD provided is ok.
