(Organized release by release) -*** Changes since GDB 5.1: +*** Changes since GDB 5.2: + +* GDB now supports C/C++ preprocessor macros. + +GDB now expands preprocessor macro invocations in C/C++ expressions, +and provides various commands for showing macro definitions and how +they expand. + +Most compilers don't include information about macros in the debugging +information by default. In GCC 3.1, for example, you need to compile +your program with the options `-gdwarf-2 -g3'. If the macro +information is present in the executable, GDB will read it. + +Here are the new commands for working with macros: + +** macro expand EXPRESSION + +Expand any macro invocations in expression, and show the result. + +** show macro MACRO-NAME + +Show the definition of the macro named MACRO-NAME, and where it was +defined. + +* Multi-arched targets. + +NEC V850 v850-*-* + +* New targets. + +Atmel AVR avr*-*-* + +* New native configurations + +Alpha NetBSD alpha*-*-netbsd* +SH NetBSD sh*-*-netbsdelf* + +* OBSOLETE configurations and files + +Configurations that have been declared obsolete in this release have +been commented out.

The default is 1024. + +* Changes in FreeBSD/i386 native debugging. + +Support for the "generate-core-file" has been added. + +* New commands "dump", "append", and "restore". + +These commands allow data to be copied from target memory +to a bfd-format or binary file (dump and append), and back +from a file into memory (restore). + +*** Changes in GDB 5.2: + +* New command "set trust-readonly-sections on[off]". + +This command is a hint that tells gdb that read-only sections +really are read-only (ie. that their contents will not change). +In this mode, gdb will go to the object file rather than the +target to read memory from read-only sections (such as ".text"). +This can be a significant performance improvement on some +(notably embedded) targets. + +* New command "generate-core-file" (or "gcore"). + +This new gdb command allows the user to drop a core file of the child +process state at any time. So far it's been implemented only for +GNU/Linux and Solaris, but should be relatively easily ported to other +hosts. Argument is core file name (defaults to core.). + +* 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. + +* Changes in ARM configurations. + +Multi-arch support is enabled for all ARM configurations. The ARM/NetBSD +configuration is fully multi-arch. * New native configurations +ARM NetBSD arm*-*-netbsd* x86 OpenBSD i[3456]86-*-openbsd* +AMD x86-64 running GNU/Linux x86_64-*-linux-* +Sparc64 running FreeBSD sparc64-*-freebsd* + +* New targets + +Sanyo XStormy16 xstormy16-elf + +* OBSOLETE configurations and files + +Configurations that have been declared obsolete in this release have +been commented out.
