Returning to the bug report at hand...
In my version of float.h I have the following (which aligns with the typedef
definitions in the std::decimal namespace).

The large code size isn't from the generated code, it's from the runtime
support in static libraries; compile main.c with -c and look at the size of
main.o.

(In reply to comment #7)
An executable with decimal float support is very big because the runtime
support is in static libraries, not in shared libraries

There's nothing strange - the runtime code is in static libraries, so all the
code for doing I/O must be linked into the executable if you use e.g. printf.

As a temporary fix I've added the following to libdfp:

This adds dfp/float.h,

n2732 says they should be defined in float.h

The definitions that n2732 wants to add are typedefs to the C++ classes, but
interoperability with C requires the typedefs using modes that Ryan shows. I

If following the spec works, then by all means do that. It's been quite a long
time since I've thought about decimal float support and my memory is a bit
