2000-01-05c-decl.c (finish_enum): Simplify code to determine minimum and maximum ↵Zack Weinberg1-49/+46
values of the enum... 2000-01-05 11:25 -0800 Zack Weinberg <zack@rabi.columbia.edu> * c-decl.c (finish_enum): Simplify code to determine minimum and maximum values of the enum, and calculate the type. Remove check for FUNCTION_DECLs in the values list, which cannot happen. Replace the DECL_INITIAL of each enumeration constant with a copy converted to the enumeration type. When updating variant types, don't bother updating the type itself. * c-typeck.c (build_binary_op): Simplify conditional expressions when weeding out spurious signed-unsigned warnings. Add new spurious warning category: if the unsigned quantity is an enum and its maximum value fits in signed_type(result_type). Update commentary. (build_conditional_expr): Warn here if one alternative is signed and the other is unsigned. From-SVN: r31244
