From: apbianco Date: Mon, 14 Jun 1999 17:15:35 +0000 (+0000) Subject: Mon Jun 14 13:13:39 1999 Alexandre Petit-Bianco X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=265dbe5d3f75b63bab85bbbb68bda6534e03e53b;p=platform%2Fupstream%2Flinaro-gcc.git Mon Jun 14 13:13:39 1999 Alexandre Petit-Bianco * parse.y (qualify_ambiguous_name): Reorganized the post evaluation of non WFL leading expression nodes. Fri Jun 11 21:37:18 1999 Alexandre Petit-Bianco * parse.y (qualify_ambiguous_name): Handle ARRAY_REF after CONVERT_EXPR. Thu Jun 10 22:26:17 1999 Alexandre Petit-Bianco * parse.y (qualify_ambiguous_name): Handle qualified expression beginning with a STRING_CST. Thu Jun 10 20:27:25 1999 Alexandre Petit-Bianco * parse.y (register_fields): Set DECL_INITIAL on both pre-initialized static and public fields. (resolve_field_access): Static field access expressions to always use pointer types. (qualify_ambiguous_name): Work out buried CALL_EXPR for proper qualification. CONVERT_EXPR to be resolved as an expression name. (java_complete_lhs): Identify and access qualified final initialized field in switch statement case expression. (fold_constant_for_init): Pre-initialized field decl constant to be folded. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@27523 138bc75d-0d04-0410-961f-82ee72b054a4 --- diff --git a/gcc/java/ChangeLog b/gcc/java/ChangeLog index de871e6..bf8e310 100644 --- a/gcc/java/ChangeLog +++ b/gcc/java/ChangeLog @@ -1,3 +1,31 @@ +Mon Jun 14 13:13:39 1999 Alexandre Petit-Bianco + + * parse.y (qualify_ambiguous_name): Reorganized the post + evaluation of non WFL leading expression nodes. + +Fri Jun 11 21:37:18 1999 Alexandre Petit-Bianco + + * parse.y (qualify_ambiguous_name): Handle ARRAY_REF after + CONVERT_EXPR. + +Thu Jun 10 22:26:17 1999 Alexandre Petit-Bianco + + * parse.y (qualify_ambiguous_name): Handle qualified expression + beginning with a STRING_CST. + +Thu Jun 10 20:27:25 1999 Alexandre Petit-Bianco + + * parse.y (register_fields): Set DECL_INITIAL on both + pre-initialized static and public fields. + (resolve_field_access): Static field access expressions to always + use pointer types. + (qualify_ambiguous_name): Work out buried CALL_EXPR for proper + qualification.
