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.
