* Firm contains a debugger extension. This allows to set debugger breakpoints
* an various events.
* The extension uses a text interface which can be accessed from most debuggers.
+ * More than one command can be given separated by ';'.
*
* @section sec_cmd Supported commands
*
+ * Historically all debugger commands start with a dot. This isn't needed in newer
+ * versions, but still supported, ie the commands ".init" and "init" are equal.
* The following commands are currently supported:
- * @b .init
+ *
+ * @b init
*
* Break immediately after the debugger extension was initialized.
* Typically this command is used in the environment to stop the execution
*
* $export FIRMDBG=".init"
*
- *
- * @b .create nr
+ * @b create nr
*
* Break if a new IR-node with node number nr was created.
* Typically used to find the place where wrong nodes are created.
*
- * @b .replace nr
+ * @b replace nr
*
* Break before IR-node with node number nr is replaced by another node.
*
- * @b .lower nr
+ * @b lower nr
*
* Break before IR-node with node number nr is lowered.
*
- * @b .remirg nr
+ * @b remirg nr
*
* Break if the irg with graph number nr is deleted.
*
- * @b .remirg name
+ * @b remirg name
*
* Break if the irg of entity name is deleted.
*
- * @b .newent nr
+ * @b newent nr
*
* Break if the entity with number nr was created.
*
- * @b .newent name
+ * @b newent name
*
* Break if the entity name was created.
*
- * @b .newtype nr
+ * @b newtype nr
*
* Break if the type with number nr was created.
*
- * @b .newtype name
+ * @b newtype name
*
* Break if the type name was created.
*
- * @b .bp
+ * @b bp
*
* Show all Firm internal breakpoints.
*
- * @b .enable nr
+ * @b enable nr
*
* Enables breakpoint nr.
*
- * @b .disable nr
+ * @b disable nr
*
* Disables breakpoint nr.
*
- * @b .setmask name lvl
+ * @b showent nr
+ *
+ * Show the content of entity nr.
+ *
+ * @b showent name
+ *
+ * Show the content of entity name.
+ *
+ * @b showtype nr
+ *
+ * Show the content of type nr.
+ *
+ * @b showtype name
+ *
+ * Show the content of type name.
+ *
+ * @b setmask name msk
+ *
+ * Sets the debug module name to mask msk.
+ *
+ * @b setlvl name lvl
*
* Sets the debug module name to level lvl.
*
- * @b .setoutfile name file
+ * @b setoutfile name file
*
* Redirects debug output of module name to file.
*
- * @b .help
+ * @b irgname name
+ *
+ * Prints address and graph number of a method given by its name.
+ *
+ * @b irgldname name
+ *
+ * Prints address and graph number of a method given by its linker name.
+ *
+ * @b help
*
* List all commands.
*
* The following example shows how to set a creation breakpoint in GDB when
* node 2101 is created.
*
- * -# set FIRMDBG=".init"
+ * -# set FIRMDBG="init"
* -# start gdb with your compiler
* -# after gdb breaks, issue
*
- * p firm_debug(".create 2101")
+ * call firm_debug("create 2101")
*
* On the console the following text should be issued:
*
# define firm "cmd" Firm debugger extension
#
define firm
- p firm_debug($arg0)
+ call firm_debug($arg0)
end
* @endcode
*
- * Then, all Firm debugger extension commands can be access in the gdb
+ * Then, all Firm debugger extension commands can be accessed in the gdb
* console using the firm prefix, eg.:
*
- * firm ".create 2101"
- * firm ".help"
+ * firm "create 2101"
+ *
+ * firm "help"
