6 Print the full structure of the rtx that is $.
7 Works only when an inferior is executing.
11 set debug_rtx_list ($, debug_rtx_count)
15 Print the full structure of all rtx insns beginning at $.
16 Works only when an inferior is executing.
17 Uses variable debug_rtx_count to control number of insns printed:
18 debug_rtx_count > 0: print from $ on.
19 debug_rtx_count < 0: print a window around $.
21 There is also debug_rtx_find (rtx, uid) that will scan a list for UID and print
22 it using debug_rtx_list. Usage example: set $foo=debug_rtx_find(first, 42)
30 Print the full structure of the tree that is $.
31 Works only when an inferior is executing.
39 Print the tree that is $ in C syntax.
40 Works only when an inferior is executing.
44 output (enum tree_code) $.common.code
49 Print the tree-code of the tree node that is $.
53 output $.decl.name->identifier.pointer
58 Print the name of the decl-node that is $.
62 output $.type.name->decl.name->identifier.pointer
67 Print the name of the type-node that is $.
71 output (enum rtx_code) $.code
78 Print the rtx-code and machine mode of the rtx that is $.
86 Print the fields of an instruction that is $.
90 set print_binding_stack ()
94 In cc1plus, print the current binding stack, frame by frame, up to and
95 including the global binding level.
98 # Put breakpoints at exit and fancy_abort in case abort is mapped
99 # to either fprintf/exit or fancy_abort.
102 # Make gdb complain about symbol reading errors. This is so that gcc
103 # developers can see and fix bugs in gcc debug output.
106 # Don't let abort actually run, as it will make
107 # stdio stop working and therefore the `pr' command above as well.
108 # Put this last because gcc does not reference it any more unless
109 # USE_SYSTEM_ABORT is defined, so gdb may complain and bail out.
