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

document pge

Print the expression that is $ in C syntax.

Works only when an inferior is executing.

end

end

define pdn

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

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 $.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

set bitmap_print (stderr, $, "", "\n")

end

document pbm

Dump the bitmap that is in $ as a comma-separated list of numbers.

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

# 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.
