Authored by jacob_hansen on May 19 2016, 2:25 AM.



Following patch D19265 which enable software floating point support in the Sparc backend, this patch enables the option to be enabled in the front-end using the -msoft-float option.

The user should ensure a library (such as the builtins from Compiler-RT) that includes the software floating point routines is provided.
