Hi folks,
On both 4.7-RC1 and STABLE (cvsup'ed at about 8 AM GMT today) I get the
following "warnings" when starting gdb :
$ gdb a.out
GNU gdb 4.18 (FreeBSD)

This GDB was configured as "i386-unknown-freebsd"...Deprecated bfd_read
called at
/usr/src/gnu/usr.bin/binutils/gdb/../../../../contrib/gdb/gdb/dbxread.c
line 2627 in elfstab_build_psymtabs
Deprecated bfd_read called at
/usr/src/gnu/usr.bin/binutils/gdb/../../../../contrib/gdb/gdb/dbxread.c
line 933 in fill_symbuf
(gdb)
Once started, gdb functions as usual.
These annoying messages are most likely caused by the recent import of
new binutils. It was also reported to -stable by Aurelien Nephtali on 3
Sep 2002.
An obvious solution is to replace all calls to "bfd_read" in
"/usr/src/contrib/gdb/gdb/dbxread.c" with the appropriate call to
"bfd_bread". I have done this, and it works (see attached patch).
Probably the same should be done for the files "coffread.c",
"dwarfread.c" and
"dwarf2read.c". I have no way to test that however, and consequently
have not done that.
I hope this solution still makes it into 4.7-RELEASE. The warnings look
quite silly, and it is easy to patch.
Kind regards,
Hans
