Subject: Fix "void debug (const tree_node *ptr)"
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=76671eb3142f9827691fcb08ca7938624221104e;p=thirdparty%2Fgcc.git

Fix "void debug (const tree_node *ptr)"

Calling "debug (const tree_node *ptr)" does nothing.  Change it to
call debug_tree so that we can do this in gdb:

(gdb) whatis type
type = const_tree
(gdb) call debug (type)
 <real_type 0x7fffe982f2a0 float sizes-gimplified SF
    size <integer_cst 0x7fffe98204e0 type <integer_type 0x7fffe98280a8 bitsizetype> constant 32>
    unit-size <integer_cst 0x7fffe98204f8 type <integer_type 0x7fffe9828000 sizetype> constant 4>
    align:32 warn_if_not_align:0 symtab:0 alias-set -1 canonical-type 0x7fffe982f2a0 precision:32
    pointer_to_this <pointer_type 0x7fffe982f930>>
(gdb)

	PR debug/120902
	* print-tree.cc (debug with const tree_node *): Call debug_tree
	instead of debug.
