* 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 <apbianco@redhat.com>
* parse.y (java_complete_lhs): Allow final locals in CASE_EXPRs.
Fixes PR java/1413
2001-08-28 Alexandre Petit-Bianco <apbianco@redhat.com>
* 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.
