*** Changes in GDB 6.0:
|
||||||
|
|
||||||
|
* New backtrace mechanism (includes DWARF 2 Call Frame Information).
|
||||||
|
|
||||||
|
DWARF 2's Call Frame Information makes available compiler generated
|
||||||
|
information that more exactly describes the program's run-time stack.
|
||||||
|
By using this information, GDB is able to provide more robust stack
|
||||||
|
backtraces.
|
||||||
|
|
||||||
|
The i386, amd64 (nee, x86-64), Alpha, m68hc11, ia64, and m32r targets
|
||||||
|
have been updated to use a new backtrace mechanism which includes
|
||||||
|
DWARF 2 CFI support.
|
||||||
|
|
||||||
|
* Hosted file I/O.
|
||||||
|
|
||||||
|
GDB's remote protocol has been extended to include support for hosted
|
||||||
|
file I/O (where the remote target uses GDB's file system). See GDB's
|
||||||
|
remote protocol documentation for details.
|
||||||
|
|
||||||
|
* All targets using the new architecture framework.
|
||||||
|
|
||||||
|
All of GDB's targets have been updated to use the new internal
|
||||||
|
architecture framework. The way is now open for future GDB releases
|
||||||
|
to include cross-architecture native debugging support (i386 on amd64,
|
||||||
|
ppc32 on ppc64).
|
||||||
|
|
||||||
|
* GNU/Linux's Thread Local Storage (TLS)
|
||||||
|
|
||||||
|
GDB now includes support for for the GNU/Linux implementation of
|
||||||
|
per-thread variables.
|
||||||
|
|
||||||
|
* GNU/Linux's Native POSIX Thread Library (NPTL)
|
||||||
|
|
||||||
|
GDB's thread code has been updated to work with either the new
|
||||||
|
GNU/Linux NPTL thread library or the older "LinuxThreads" library.
|
||||||
|
|
||||||
|
* Separate debug info.
|
||||||
|
|
||||||
|
GDB, in conjunction with BINUTILS, now supports a mechanism for
|
||||||
|
automatically loading debug information from a separate file. Instead
|
||||||
|
of shipping full debug and non-debug versions of system libraries,
|
||||||
|
system integrators can now instead ship just the stripped libraries
|
||||||
|
and optional debug files.
|
||||||
|
|
||||||
|
* DWARF 2 Location Expressions
|
||||||
|
|
||||||
|
DWARF 2 Location Expressions allow the compiler to more completely
|
||||||
|
describe the location of variables (even in optimized code) to the
|
||||||
|
debugger.
|
||||||
|
|
||||||
|
GDB now includes preliminary support for location expressions (support
|
||||||
|
for DW_OP_piece is still missing).
|
||||||
|
|
||||||
|
* Java
|
||||||
|
|
||||||
|
A number of long standing bugs that caused GDB to die while starting a
|
||||||
|
Java application have been fixed. GDB's Java support is now
|
||||||
|
considered "useable".
|
||||||

||||||

GDB's SPARC, MIPS and PowerPC targets, in 6.0, have not been updated
|
||||||
|
to use the new frame mechanism.
|
||||||
|
|
||||||
|
People encountering problems with these targets should consult GDB's
|
||||||
|
web pages and mailing lists (http://www.gnu.org/software/gdb/) to see
|
||||||
|
if there is an update.
|
||||||
|
|
||||||
|
arm-*-*
|
||||||
|
|
||||||
|
GDB's ARM target, in 6.0, has not been updated to use the new frame
|
||||||
|
mechanism.
|
||||||
|
|
||||||
|
Fortunatly the ARM target, in the GDB's mainline sources, has been
|
||||||
|
updated so people encountering problems should consider downloading a
|
||||||
|
more current GDB (http://www.gnu.org/software/gdb/current).
