* gnat1drv.adb: Minor: complete previous change.
2015-01-06 Olivier Hainque <hainque@adacore.com>
* set_targ.ads (C_Type_For): New function. Return the name of
a C type supported by the back-end and suitable as a basis to
construct the standard Ada floating point type identified by
the T parameter. This is used as a common ground to feed both
ttypes values and the GNAT tree nodes for the standard floating
point types.
* set_targ.adb (Long_Double_Index): The index at which "long
double" gets registered in the FPT_Mode_Table. This is useful to
know whether we have a "long double" available at all and get at
it's characteristics without having to search the FPT_Mode_Table
when we need to decide which C type should be used as the
basis for Long_Long_Float in Ada.
(Register_Float_Type): Fill Long_Double_Index.
(FPT_Mode_Index_For): New function. Return the index in
FPT_Mode_Table that designates the entry corresponding to the
provided C type name.
(FPT_Mode_Index_For): New function. Return the index in
FPT_Mode_Table that designates the entry for a back-end type
suitable as a basis to construct the standard Ada floating point
type identified by the input T parameter.
(elaboration code): Register_Back_End_Types unconditionally,
so C_Type_For can operate regardless of -gnateT. Do it
early so we can query it for the floating point sizes, via
FPT_Mode_Index_For. Initialize Float_Size, Double_Size and
Long_Double_Size from the FPT_Mode_Table, as cstand will do.
* cstand.adb (Create_Float_Types): Use C_Type_For to determine
which C type should be used as the basis for the construction
of the Standard Ada floating point types.
