Hi Sebastian. > Why would you use > this instead of -mfloat-abi=hard? For a statically linked executable > this makes little sense. My goal is to link with a 3rd party object file which had been compiled with -mfloat-abi=softfp and which cannot be recompiled. In fact, there are also other flags which might cause a conflict with the current flags used by RTEMS and which might cause even more headache (-mfpu comes to my mind). > If you really need such a multilib, then you can patch > gcc/config/arm/t-rtems.

arm bsps: changing the float-abi to softfp
Hi, we are currently using the RTEMS source builder to build the toolchain, RTEMS and a few BSPs for ARM (32bit) targets. Apparently, RTEMS generally uses -mfloat-abi=hard for all arm32 targets. Can this easily be changed to compile with -mfloat-abi=softfp instead? Or extend the multilib build to include also softfp variants? No "clean" solution expected which is ready for inclusion in rtems.org -- just a pointer to the relevant files which would have to be patched. Kind regards Ingolf ___ users mailing list users@rtems.org http://lists.rtems.org/mailman/listinfo/users
