From: Jan Kratochvil Date: Thu, 2 Sep 2010 15:42:03 +0000 (+0000) Subject: gdb/ X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=58b61394cfd1f96444c1debd9ba9e0ea69d439f2;p=binutils-gdb.git gdb/ * cli-logging.c: Include gdb_assert.h. (set_logging_overwrite): New function. (logging_redirect): New comment. (logging_no_redirect_file, set_logging_redirect) (pop_output_files) : New. (handle_redirections) : New variable no_redirect_file. Remove file autoclose for tee_file_new. No longer discard cleanup for the close of former OUTPUT. Set LOGGING_NO_REDIRECT_FILE. (handle_redirections) : gdb_assert LOGGING_NO_REDIRECT_FILE. (show_logging_command) : Adjust messages for SAVED_FILENAME not NULL. (_initialize_cli_logging): Install set_logging_overwrite and set_logging_redirect. --- diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 2d2344c9873..cf7f2bd4128 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,21 @@ +2010-09-02 Jan Kratochvil + + * cli-logging.c: Include gdb_assert.h. + (set_logging_overwrite): New function. + (logging_redirect): New comment. + (logging_no_redirect_file, set_logging_redirect) + (pop_output_files) : New. + (handle_redirections) : New variable + no_redirect_file.
