Author: emaste Date: Fri Oct 7 12:57:35 2016 New Revision: 306806 URL: https://svnweb.freebsd.org/changeset/base/306806
Log: Improvements to BSD-licensed DTC. - Numerous crash and bug fixes - Improved warning and error messages - Permit multiple labels on nodes and properties - Fix node@address references - Add support for /delete-node/ - Consume whitespace after a node - Read the next token before the second /memreserve/ - Fix parsing of whitespace - Clean up /delete-node/ and add support for /delete-property/ - Handle /delete-node/ specifying a unit address Obtained from: https://github.com/davidchisnall/dtc @df5ede4 Modified: head/usr.bin/dtc/checking.cc head/usr.bin/dtc/checking.hh head/usr.bin/dtc/dtb.cc head/usr.bin/dtc/dtb.hh head/usr.bin/dtc/dtc.1 head/usr.bin/dtc/dtc.cc head/usr.bin/dtc/fdt.cc head/usr.bin/dtc/fdt.hh head/usr.bin/dtc/input_buffer.cc head/usr.bin/dtc/input_buffer.hh head/usr.bin/dtc/string.cc head/usr.bin/dtc/util.hh Modified: head/usr.bin/dtc/checking.cc ============================================================================== --- head/usr.bin/dtc/checking.cc Fri Oct 7 11:50:59 2016 (r306805) +++ head/usr.bin/dtc/checking.cc Fri Oct 7 12:57:35 2016 (r306806) @@ -33,7 +33,7 @@ #include "checking.hh" #include <stdio.h> - +using std::string; namespace dtc { @@ -44,6 +44,30 @@ namespace checking namespace { + struct deleted_node_checker : public checker + { + deleted_node_checker(const char *name) : checker(name) {} + virtual bool check_node(device_tree *, const node_ptr &n) + { + auto &deleted = n->deleted_child_nodes(); + if (deleted.empty()) + { + return true; + } + bool plural = deleted.size() > 1; + string errmsg("Attempts to delete "); + errmsg += plural ?
