DOS/Windows-related changes in the gprof subdirectory
- To: binutils@sourceware.cygnus.com
- Subject: DOS/Windows-related changes in the gprof subdirectory
- From: Eli Zaretskii <eliz@gnu.org>
- Date: Mon, 6 Sep 1999 04:17:06 -0400
The follwoing changes solve DOS/Windows-related problems, mainly with
file names and text/binary mode I/O.
1999-07-30 Eli Zaretskii <eliz@is.elta.co.il>
* gmon_io.h (SET_BINARY) [O_BINARY]: Define.
* gmon_io.c (gmon_out_read) [SET_BINARY]: Switch stdin into binary
mode.
* source.c: Include filenames.h and sys/stat.h.
(source_file_lookup_path, source_file_lookup_name): Use
FILENAME_CMP to compare file names.
(annotate_source) [__MSDOS__]: If "filename-ann" would overwrite
"filename", replace the extension with ".ann".
[DOSISH_FILENAMES]: Support file names with backslashes and drive
letters.
Use IS_ABSOLUTE.
1999-07-27 Eli Zaretskii <eliz@is.elta.co.il>
* search_list.h (PATH_SEP_CHAR): Define.
* search_list.c (search_list_append): Use PATH_SEP_CHAR.
* hertz.c (HERTZ) [__MSDOS__]: Don't define unless they have
neither HAVE_SETITIMER nor HAVE_SYSCONF.
[HAVE_SETITIMER]: If they define both HAVE_SETITIMER and
HAVE_SYSCONF, try setitimer and fall back on sysconf.
