* ptype/o prints offsets and sizes of members (like pahole)
* tab-completion improved: quoting function names is not generally
necessary anymore, completion offers for breakpoint don't include
data symbol
* enable/disable breakpoints now accept ranges: 'disable 1.3-5'
* new commands:
- set/show cwd: working directory of debuggee
- set/show compile-gcc: program to use for 'compile' command
- starti: start program and stop at first instruction
- TUI single-key commands: 'i' for stepi and 'o' for nexti
* --readnever option disables any reading of debug info (for dumping)
* s390: guarded storage register access for z14
* gcore option -a dumps all memory mapping
* C++ breakpoints: 'b foo' will now set a breakpoint on all functions
and methods named 'foo' no matter the scope. Use -qualified if you
don't want that
* python scripting: new events gdb.new_inferior, gdb.inferior_deleted
and gdb.new_thread; new command rbreak (breakpoint accepting regexps)
* gdbserver can be passed environment parameters to remote debuggee
- Added patches from Fedora:
gdb-ppc64-stwux-tautological-compare.patch
gdb-rhbz1540559-gdbaddindex-glibcdebug-regression.patch
gdb-vla-intel-fix-print-char-array.patch
- Removed unused gdb-libstdc++-v3-python-7.1.1-20170526.tar.bz2
- Removed obsolete upstream patches:
gdb-s390x-1b63490.patch
gdb-s390x-289e23a.patch
gdb-s390x-8fe09d7.patch

Subject: gdb-6.5-sharedlibrary-path.patch
|
|
|
|
FileName: gdb-6.5-sharedlibrary-path.patch
|
|
|
|
;; Fix TLS symbols resolving for shared libraries with a relative pathname.
|
|
;; The testsuite needs `gdb-6.5-tls-of-separate-debuginfo.patch'.
|
|
;;=fedoratest: One should recheck if it is really fixed upstream.
|
|
|
|
If you provided some relative path to the shared library, such as with
|
|
export LD_LIBRARY_PATH=.
|
|
then gdb would fail to match the shared library name during the TLS lookup.
|
|
|
|
Dropped the workaround/fix for gdb-6.8.50.20081128 - is it still needed?
|
|
|
|
The testsuite needs `gdb-6.3-bz146810-solib_absolute_prefix_is_empty.patch'.
|
|
The testsuite needs `gdb-6.5-tls-of-separate-debuginfo.patch'.
|
|
|
|
2006-09-01 Jan Kratochvil <jan.kratochvil@redhat.com>
|
|
|
|
* solib-svr4.c (svr4_fetch_objfile_link_map): Match even absolute
|
|
requested pathnames to the internal loaded relative pathnames.
|
|
|
|
2007-10-16 Jan Kratochvil <jan.kratochvil@redhat.com>
|
|
|
|
Port to GDB-6.7.
|
|
|
|
2008-02-27 Jan Kratochvil <jan.kratochvil@redhat.com>
|
|
|
|
Port to gdb-6.7.50.20080227.
