The attached set of patches add long double support for i386, aarch64 and x86_64. The riscv and powerpc are supported by FreeBSD but will need more work to be supported by newlib. FreeBSD has separate 64 and 32 bit powerpc support which would have to be integrated for newlib. FreeBSD riscv support is 64 and there are issues with fenv.h that would have to be addressed. The first patch is FreeBSD source. Most of the source resides in three directories ld, ld128, and ld80. These contain the long double methods. The ld128 and ld80 are enabled based on the architecture. I also added the FreeBSD sys/endian.h file which was required to build. Finally, an architecture machine/_fpmath.h file was copied from FreeBSD for each architecture the methods are to be built with. The existence of this file is used to trigger the FreeBSD long double math methods to build. If the architecture does not have _fpmath.h the LDBL_EQ_DBL files are built instead. The second patch contains the modifications necessary to build in newlib. In FreeBSD some header files from any of the three directories are visible to all the source files. The include statements were modified so the header file was pulled from the required directory (e.g, “file.h” was changed to “ld/file.h”). The files invtrig.h and k_expl.h were created in the ld directory and conditionally include either the ld128 or the ld80 version of that header file. If the configure/makefile magic were changed it might be possible to adjust the include arguments to the compiler rather than the include statements. Also in the second patch, some of the _fpmath.h and a couple of the source files unsigned long and unsigned int were changed to fixed width types so different sized unsigned long could be accommodated. The FreeBSD file s_nearbyint.c contained the methods nearbyint, nearbyintf, and nearbyintl. This file name was changed to s_nearbyintl.c and the methods nearbyint and nearbyintf were removed from the compile to resolve conflicts. Finally, since long double support shouldn’t be considered rare anymore prototypes in math.h are no longer conditional.
