to the same class-wide type.

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

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.
* get_targ.ads (Get_Float_Size, Get_Double_Size,
Get_Long_Double_Size): Remove.

If named types with similar names are defined inside of methods
with similar names, it was possible that the mangled type names would be
the same, leading to multiple definitions of type descriptor and
garbage collection info variables.
This can only occur with similarly named methods across different
receivers, so we use the receiver name to distinguish.
Fixes issue 33.

With my last change, `sed' is used to cut out the target name from a listed
target. Since there may be additional OPTions encoded in the "target", I tried
to get only the first submatch before an `OPT'. However, `sed' uses longest
match, so I'm re-writing this using awk.
If anybody is like using `gawk' or anything different, please feel free to
drop another patch. Since this is usually called by hand or by robots under
review, I don't see much of a problem here.
