fp-test.cc - Check that all floating-point operations are available. Copyright (C) 1995-2024 Free Software Foundation, Inc. Contributed by Ronald F. Guilmette <rfg@monkeys.com>. This file is part of GCC. GCC is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 3, or (at your option) any later version.

This is a trivial test program which may be useful to people who are porting the GCC or G++ compilers to a new system. The intent here is merely to check that all floating-point operations have been provided by the port. (Note that I say ``provided'' rather than ``implemented''.) To use this file, simply compile it (with GCC or G++) and then try to link it in the normal way (also using GCC or G++ respectively). If all of the floating -point operations (including conversions) have been provided, then this file will link without incident. If however one or more of the primitive floating-point operations have not been properly provided, you will get link-time errors indicating which floating-point operations are unavailable. This file will typically be used when porting the GNU compilers to some system which lacks floating-point hardware, and for which software emulation routines (for FP ops) are needed in order to complete the port.
