define pr set debug_rtx ($) end document pr Print the full structure of the rtx that is $. Works only when an inferior is executing. end define prl set debug_rtx_list ($, debug_rtx_count) end document prl Print the full structure of all rtx insns beginning at $. Works only when an inferior is executing. Uses variable debug_rtx_count to control number of insns printed: debug_rtx_count > 0: print from $ on. debug_rtx_count < 0: print a window around $. There is also debug_rtx_find (rtx, uid) that will scan a list for UID and print it using debug_rtx_list. Usage example: set $foo=debug_rtx_find(first, 42) end define pt set debug_tree ($) end document pt Print the full structure of the tree that is $. Works only when an inferior is executing. end define ptc output (enum tree_code) $.common.code echo \n end document ptc Print the tree-code of the tree node that is $. end define pdn output $.decl.name->identifier.pointer echo \n end document pdn Print the name of the decl-node that is $. end define ptn output $.type.name->decl.name->identifier.pointer echo \n end document ptn Print the name of the type-node that is $. end define prc output (enum rtx_code) $.code echo \ ( output $.mode echo )\n end document prc Print the rtx-code and machine mode of the rtx that is $. end define pi print $.fld[0].rtx@7 end document pi Print the fields of an instruction that is $. end define pbs set print_binding_stack () end document pbs In cc1plus, print the current binding stack, frame by frame, up to and including the global binding level. end # Put breakpoints at exit and fancy_abort in case abort is mapped # to either fprintf/exit or fancy_abort. b exit b fancy_abort # Make gdb complain about symbol reading errors.
