For targets with IEEE support but without the issignaling macro in libc (currently, everywhere except glibc), this allows us to provide a fallback implementation. In order to keep the code in ieee_helper.c relatively readable, I've put that new implementation in a separate file, issignaling_fallback.h. libgfortran/ChangeLog: * ieee/issignaling_fallback.h: New file. * ieee/ieee_helper.c: Include issignaling_fallback.h when target does not define issignaling macro. gcc/testsuite/ChangeLog: * gfortran.dg/ieee/signaling_1.f90: Do not require issignaling. * gfortran.dg/ieee/signaling_2.f90: Add comment. * gfortran.dg/ieee/signaling_3.f90: New test.
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
