MIPS32 support different FP modes (32,xx,64), so give the user the opportunity to choose between them. That will cause host-gcc to be built using the --with-fp-32=[32|xx|64] configure option. Also the -mfp[32|xx|64] gcc option will be added to TARGET_CFLAGS and to the toolchain wrapper. FP mode option shouldn't be used for soft-float, so we add logic in the toolchain wrapper if -msoft-float is among the arguments in order to not append the -fp[[32|xx|64] option, otherwise the compilation may fail.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
