What has changed since GDB-3.5?
|
||||
(Organized release by release)
|
||||
|
||||
*** Changes in GDB-4.8:
|
||||
|
||||
* New features
|
||||
|
||||
GDB now supports array constants that can be used in expressions typed in by
|
||||
the user. The syntax is `{element, element, ...}'. Ie: you can now type
|
||||
`print {1, 2, 3}', and it will build up an array.
|
||||
|
||||
There is also a new directory `gdb/sparclite' that contains a program that can
|
||||
be run on a Fujitsu SPARClite processor to demonstrate how the sparc-stub
|
||||
remote stub works.
|
||||
|
||||
* Faster and better demangling
|
||||
|
||||
We have improved template demangling and fixed numerous bugs in the GNU style
|
||||
demangler. It can now handle type modifiers such as `static' or `const'. Wide
|
||||
character types (wchar_t) are now supported. Demangling of each symbol is now
|
||||
only done once, and is cached when the symbol table for a file is read in.
|
||||
This results in a moderate increase in memory usage, but a fantastic speedup in
|
||||
symbol lookups.
|
||||
|
||||
`Cfront' style demangling still doesn't work with AT&T cfront. It was written
|
||||
from the specifications in the Annotated Reference Manual, which AT&T's
|
||||
compiler does not actually implement.
|
||||
|
||||
* Improved configure script
|
||||
|
||||
The `configure' script will now attempt to guess your system type if you don't
|
||||
supply a host system type. WE CAN GIVE NO GUARANTEES ABOUT THE VALIDITY OF THE
|
||||
GUESSES MADE BY THIS METHOD. The old scheme of supplying a host system triplet
|
||||
is greatly preferable over using this. All the magic is done in the new
|
||||
`config.guess' script. Examine it for details.
|
||||
|
||||
We have also brought our configure script much more in line with the FSF's
|
||||
version. It now supports the --with-xxx options. In particular,
|
||||
`--with-minimal-bfd' is of interest to those people who want a minimal BFD
|
||||
that only supports target file formats.
|
||||
|
||||
We have also cleaned up the issue with the rpc and ptrace header files for
|
||||
VxWorks that was discovered at the last minute during the 4.7 release. You
|
||||
should now be able to build a VxWorks GDB.
|
||||
|
||||
* Documentation
|
||||
|
||||
There's lots of new internal documentation on how to modify GDB, and produce
|
||||
clean changes to the code. We implore people to look at this before submitting
|
||||
changes.
|
||||
|
||||
The GDB manual uses new, sexy Texinfo conditionals, rather than the arcane M4
|
||||
macros. This requires the use of the new Texinfo program, which is available
|
||||
from the same place that you got this copy of GDB.
|
||||
|
||||
*NOTE* The new Texinfo program produces TeX output that can cause old versions
|
||||
of TeX to hang. We're not sure exactly which versions have this problem, but
|
||||
it has been seen in 3.0. We highly recommend upgrading to TeX version 3.141 or
|
||||
better. If that isn't possible, there is a patch in `texinfo/tex3patch' that
|
||||
will modify `texinfo/texinfo.tex' to work around this problem.
|
||||
|
||||
* Mmalloc now licensed under the GNU Library General Public License
|
||||
|
||||
* New native hosts supported
|
||||
|
||||
HP/PA-RISC under HPUX using GNU tools hppa1.1-hp-hpux
|
||||
|
||||
386 CPUs running SCO Unix i386-unknown-scosysv322 or sco
|
||||
(core file support added)
|
||||
386 CPUs running SCO Unix 3.2v4 i386-unknown-sco3.2v4
|
||||
|
||||
* New targets supported
|
||||
|
||||
AMD 29k family via UDI a29k-amd-udi or udi29k
|
||||
|
||||
* New file formats supported
|
||||
|
||||
BFD now has minimal support for reading HP/PA-RISC executables (SOM?), and
|
||||
HPUX core files. We can't write them yet.
|
||||
|
||||
* New commands
|
||||
|
||||
We now accept --silent as an alias for --quiet.
|
||||
|
||||
* Major bug fixes
|
||||
|
||||
This version fixes the attach problem that many of you reported. We have
|
||||
also stomped on a bunch more printf_filtered("%s") problems.
|
||||
|
||||
You can also now ^C a gdb that is attached to a process. This will cause the
|
||||
attached process to stop, and give control back to GDB.
|
||||
|
||||
We also fixed a lot of problems associated with either not closing file
|
||||
descriptors, or using too many. This was especially a problem for programs
|
||||
that used many (~100) shared libraries.
|
||||
|
||||
|
||||

|
||||
|
||||

||||
