What has changed in GDB?
(Organized release by release)
-*** Changes since GDB 5.0:
+*** Changes since GDB 5.1:
+
+* New command line option
+
+GDB now accepts --pid or -p followed by a process id.
+
+* Change in command line behavior -- corefiles vs. process ids.
+
+There is a subtle behavior in the way in which GDB handles
+command line arguments. The first non-flag argument is always
+a program to debug, but the second non-flag argument may either
+be a corefile or a process id. Previously, GDB would attempt to
+open the second argument as a corefile, and if that failed, would
+issue a superfluous error message and then attempt to attach it as
+a process. Now, if the second argument begins with a non-digit,
+it will be treated as a corefile. If it begins with a digit,
+GDB will attempt to attach it as a process, and if no such process
+is found, will then attempt to open it as a corefile.

-* GDB has been converted to ANS/ISO C.
+* GDB has been converted to ISO C.
-GDB's source code has been converted to ANS/ISO C. In particular, the
+GDB's source code has been converted to ISO C. In particular, the
sources are fully protoized, and rely on standard headers being
present.
* Changes in GNU/Linux native debugging.
+Support for debugging multi-threaded programs has been completely
+revised for all platforms except m68k and sparc. You can now debug as
+many threads as your system allows you to have.
+
Attach/detach is supported for multi-threaded programs.
-Support for SSE registers was added.
+Support for SSE registers was added for x86. This doesn't work for
+multi-threaded programs though.
* Changes in MIPS configurations.
DWARF2 debug info is now supported.
+It is now possible to `step' and `next' through calls to `longjmp'.
+
* Changes in documentation.
All GDB documentation was converted to GFDL, the GNU Free
projects / deliverable / binutils-gdb.git / blobdiff
