From 4e0995d20fcd8b2b3f6e52e14798fd643363729a Mon Sep 17 00:00:00 2001 From: apbianco Date: Sat, 1 Sep 2001 04:42:50 +0000 Subject: 2001-08-30 Alexandre Petit-Bianco * parse.y (patch_assignment): Don't verify final re-assignment here. (java_complete_lhs): Verify assignments to finals calling patch_assignment. Verify re-assignments to finals before calling patch_assignment. 2001-08-29 Alexandre Petit-Bianco * parse.y (java_complete_lhs): Allow final locals in CASE_EXPRs. Fixes PR java/1413 2001-08-28 Alexandre Petit-Bianco * lex.c (java_lex): new local found_hex_digits. Set and then used in test to reject invalid hexadecimal numbers. * parse.y (java_complete_tree): Prevent unwanted cast with initialized floating point finals. (patch_binop): Emit a warning when detecting a division by zero, mark result not constant, don't simplify non integer division.
