Comment (by bdubbs):
* Changes in GDB 8.2
* The 'set disassembler-options' command now supports specifying options
for the MIPS target.
* The 'symbol-file' command now accepts an '-o' option to add a relative
offset to all sections.
* Similarly, the 'add-symbol-file' command also accepts an '-o' option to
add
a relative offset to all sections, but it allows to override the load
address of individual sections using '-s'.
* The 'add-symbol-file' command no longer requires the second argument
(address of the text section).
* The endianness used with the 'set endian auto' mode in the absence of
an executable selected for debugging is now the last endianness chosen
either by one of the 'set endian big' and 'set endian little' commands
or by inferring from the last executable used, rather than the startup
default.
* The pager now allows a "c" response, meaning to disable the pager
for the rest of the current command.
* The commands 'info variables/functions/types' now show the source line
numbers of symbol definitions when available.
* 'info proc' now works on running processes on FreeBSD systems and core
files created on FreeBSD systems.
* C expressions can now use _Alignof, and C++ expressions can now use
alignof.
* Support for SVE on AArch64 Linux. Note that GDB does not detect changes
to
the vector length while the process is running.
* New commands
set debug fbsd-nat
show debug fbsd-nat
Control display of debugging info regarding the FreeBSD native target.
set|show varsize-limit
This new setting allows the user to control the maximum size of Ada
objects being printed when those objects have a variable type,
instead of that maximum size being hardcoded to 65536 bytes.
set|show record btrace cpu
Controls the processor to be used for enabling errata workarounds for
branch trace decode.
maint check libthread-db
Run integrity checks on the current inferior's thread debugging
library
maint set check-libthread-db (on|off)
maint show check-libthread-db
Control whether to run integrity checks on inferior specific thread
debugging libraries as they are loaded. The default is not to
perform such checks.
* Python API
* Type alignment is now exposed via the "align" attribute of a
gdb.Type.
* The commands attached to a breakpoint can be set by assigning to
the breakpoint's "commands" field.
* gdb.execute can now execute multi-line gdb commands.
* The new functions gdb.convenience_variable and
gdb.set_convenience_variable can be used to get and set the value
of convenience variables.
* A gdb.Parameter will no longer print the "set" help text on an
ordinary "set"; instead by default a "set" will be silent unless
the get_set_string method returns a non-empty string.
* New targets
RiscV ELF riscv*-*-elf
* Removed targets and native configurations
m88k running OpenBSD m88*-*-openbsd*
SH-5/SH64 ELF sh64-*-elf*, SH-5/SH64 support in sh*
SH-5/SH64 running GNU/Linux SH-5/SH64 support in sh*-*-linux*
SH-5/SH64 running OpenBSD SH-5/SH64 support in sh*-*-openbsd*
* Aarch64/Linux hardware watchpoints improvements
Hardware watchpoints on unaligned addresses are now properly
supported when running Linux kernel 4.10 or higher: read and access
watchpoints are no longer spuriously missed, and all watchpoints
lengths between 1 and 8 bytes are supported. On older kernels,
watchpoints set on unaligned addresses are no longer missed, with
the tradeoff that there is a possibility of false hits being
reported.
* New configure options
--enable-codesign=CERT
This can be used to invoke "codesign -s CERT" after building gdb.
This option is useful on macOS, where code signing is required for
gdb to work properly.
