re PR ada/30740 (Improper semantics in gnat's compilation of certain expressions involving modular arithmetic)
2008-05-20 Robert Dewar <dewar@adacore.com>
PR ada/30740
* einfo.ads, einfo.adb (Non_Binary_Modulus): Applies to all types and
subtypes, always False for non-modular types.
Shared_Var_Assign_Proc (node22) and Shared_Var_Read_Proc (node 15)
entry nodes have been replaced by Shared_Var_Procs_Instance (node22)
for Shared_Storage package.
(Is_RACW_Stub_Type): New entity flag.
* exp_ch4.adb
(Expand_N_Op_Expon): Avoid incorrect optimization of a*(2**b) in the
case where we have a modular type with a non-binary modules.
Comments reformattings.
* sem_intr.adb: Simplify code not that Non_Binary_Modulus applies to
all types.
