lang.c (flag_use_divide_subroutine): New variable.
1999-07-15 Andrew Haley <aph@cygnus.com>
* lang.c (flag_use_divide_subroutine): New variable.
* typeck.c: (convert_ieee_real_to_integer): Bounds check
fp-to-integer conversion.
(convert): Call convert_ieee_real_to_integer when flag_fast_math
is not set.
* expr.c (build_java_soft_divmod): New function.
(build_java_binop): Call build_java_soft_divmod if
flag_use_divide_subroutine is set.
* decl.c: soft_idiv_node, soft_irem_node, soft_ldiv_node, tree
soft_lrem_node: new builtin functions.
(init_decl_processing) Initialize the new builtins.
* java-tree.h soft_idiv_node, soft_irem_node, soft_ldiv_node, tree
soft_lrem_node: new builtin functions.
(build_java_soft_divmod): New function.
* parse.y: Call build_java_soft_divmod if
flag_use_divide_subroutine is set.
* parse.c: Rebuilt.
* jvspec.c (lang_specific_driver): Always allow an extra arg (for
a --specs= arg) even if not linking.
* lang-options.h (DEFINE_LANG_NAME ("Java")): Add
-fuse-divide-subroutine
