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.
35 output (enum tree_code) $.common.code
40 Print the tree-code of the tree node that is $.
44 output $.decl.name->identifier.pointer
49 Print the name of the decl-node that is $.
53 output $.type.name->decl.name->identifier.pointer
58 Print the name of the type-node that is $.
62 output (enum rtx_code) $.code
69 Print the rtx-code and machine mode of the rtx that is $.
77 Print the fields of an instruction that is $.
81 set print_binding_stack ()
85 In cc1plus, print the current binding stack, frame by frame, up to and
86 including the global binding level.
89 # Put breakpoints at exit and fancy_abort in case abort is mapped
90 # to either fprintf/exit or fancy_abort.
93 # Make gdb complain about symbol reading errors. This is so that gcc
94 # developers can see and fix bugs in gcc debug output.
97 # Don't let abort actually run, as it will make
98 # stdio stop working and therefore the `pr' command above as well.
99 # Put this last because gcc does not reference it any more unless
100 # USE_SYSTEM_ABORT is defined, so gdb may complain and bail out.
