in a successor block for every block...resulting in some O(N^k) algorithm which wasn't very good for performance. Calculating this information up front and keeping it in a map made it much faster. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@30697 91177308-0d34-0410-b5e6-96231b3b80d8

2006-09-28Fix PR902:Reid Spencer
Errors are generated with the YYERROR macro which can only be called from a production (inside yyparse) because of the goto statement in the macro. This lead to several situations where GEN_ERROR was not called but GenerateError was used instead (because it doesn't use YYERROR). However, in such situations, catching the error much later (e.g. at the end of the production) is not sufficient because LLVM can assert on invalid data before the end of the production is reached. The solution is to ensure that the CHECK_FOR_ERROR macro (which invokes YYERROR if there's an error) is used as soon as possible after a call to GenerateError has been made. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@30650 91177308-0d34-0410-b5e6-96231b3b80d8
