(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. + + + * Library changes + + * Configuration + + * New hosts supported + + +PA/HPUX support (cleaned up), uses unwind info, needs gcc/gas... +HP300 native support (???) +Vax Ultrix native (was already there) +step only goes into a subr if there is line # info present +rs6000 bug fixes... +Language interfaces +VxWorks/rpc problems resolved +symbols/psymbols/msymbols combined +Lotsa host/native/target stuff cleaned up + +Don Allen +Gerald Baumgartner +Michael Ben-Gershon +Art Berggreen +Karl Berry +Per Bothner +Ralph Campbell +John Carr +Steve Chamberlain +Lee W.
