--- Comment #23 from anlauf at gcc dot gnu.org --- (In reply to jos...@codesourcery.com from comment #22) > Closely related: the LONG_DOUBLE_TYPE_SIZE target macro which assumes > "size in bits" can uniquely determine the format of long double. In the > absence of hacks such as the above, LONG_DOUBLE_TYPE_SIZE needs replacing > by a target hook that returns the machine mode, not "size in bits" (maybe > a hook that covers all of float, double and long double). Remember that Fortran needs a correspondence between a storage representation (in bytes / bits) and the kind type on the language side. We'd thus need a method to get the machine mode for a given representation. If there are multiple representations with the same storage size (ieee128 vs. ibm128), the ME needs to provide a way to the FE to uniquely address those.
