15427 (store_killed_after): Add parameter to say whether to do the

15431 vectors properly, and somewhat optimized.
15432 (store_motion): Init the df_analyzer, get REG_DEF chains.

19181
19182 * c-common.h (enum rid): Add RID_FIRST_AT, RID_LAST_AT,
19183 RID_LAST_PQ. Move RID_FIRST_PQ down with the other FIRST/LAST
19184 enumerators.
19185 (OBJC_IS_AT_KEYWORD, OBJC_IS_PQ_KEYWORD): New macros.
19186
19187 * c-parse.in (OBJC_STRING): Kill.
19188 (objc_string): Decompose to [objc_string] '@' STRING.
19189 (reswords): Take the leading '@' off all the Objective-C keywords.

19194 an '@'; if we get an identifier, check whether it's an
19195 Objective-C @-keyword. If so, return the keyword. Otherwise,
19196 put back the token and return the '@' as a terminal.
19197
19198 * cpplib.c (lex_macro_node): Remove unnecessary check for
19199 leading '@' on identifier. Clarify control flow and commentary.
