Soft-FP sh3eb port of OpenLibm
This is a fork of OpenLibm with support for the sh3eb architecture, intended for add-in programming on fx-9860G and fx-CG 50.
Building
You will need a GCC toolchain built with --target=sh3eb-elf, such as the
sh-elf-gcc commonly used on Planète Casio.
First locate the compiler's install directory. This is normally the
lib/gcc/sh3eb-elf/<version>/ folder inside the install path of the compiler.
% PREFIX=$(sh-elf-gcc --print-search-dirs | grep install | sed 's/install: //')
You can then build and install the static libopenlibm.a archive and the headers.
% make USEGCC=1 TOOLPREFIX=sh-elf- libdir="$PREFIX" includedir="$PREFIX/include" install-static install-headers
Using in a program
Simply link with -lopenlibm as you would do with -lm.
