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 pct
set debug_c_tree ($)
end

document pct
Print the tree that is $ in C syntax.
Works only when an inferior is executing.
end

define pgs
set debug_generic_stmt ($)
end

document pgs
Print the statement that is $ in C syntax.
Works only when an inferior is executing.
end

define pge
set debug_generic_expr ($)
end

echo \n
end

document pdn
Print the name of the decl-node that is $.
end

define ptn

echo \n
end

document ptn
Print the name of the type-node that is $.
end

define prc

echo \ (
output $.mode
echo )\n
end

document prc
Print the rtx-code and machine mode of the rtx that is $.
end

define pi
print $.u.fld[0].rt_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

define pbb
set dump_bb ($, stderr, 0)
end

document pbb
Dump the basic block that is in $, including rtx.
end

define pbm

end

document pbm

# Put breakpoints at exit and fancy_abort in case abort is mapped
# to either fprintf/exit or fancy_abort.
b fancy_abort

# Put a breakpoint on internal_error to help with debugging ICEs.
b internal_error

# Make gdb complain about symbol reading errors.  This is so that gcc
# developers can see and fix bugs in gcc debug output.
set complaints 20

# Don't let abort actually run, as it will make
# stdio stop working and therefore the `pr' command above as well.
# Put this last because gcc does not reference it any more unless
# USE_SYSTEM_ABORT is defined, so gdb may complain and bail out.

b abort
