  "message": "lift handling of -\u003eimmutable into dup_token()\n\nWe need to make sure that any struct string with more than one token\nrefering to it will have -\u003eimmutable set; that\u0027s what de1fa7e60 (\"Make\nmacro expanded string immutable\") tried to achieve.  Unfortunately, it\nwas not enough - constructing an example where an unexpanded argument gets\nseveral copies is very easy (see the testcase in this commit).\n\nA better place for dealing with that is dup_token() - that\u0027s guaranteed\nto catch all such tokens and with sane code generation (\u003d\u003d with compiler\nmade certain that *streampos can\u0027t be altered by stores to alloc-\u003epos)\nit\u0027s quite cheap; we already have alloc-\u003epos in registers and checking\nif the lower 6 bits happen to be 001000 or 001001 (TOKEN_STRING and\nTOKEN_WIDE_STRING resp.) doesn\u0027t take much.\n\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n",
