...that assume a C-like front-end (C, C++ or ObjC): calls are made to decl_constant_value, iasm_build_bracket and similar routines that mostly aren't defined by the Ada, fortran and java front-ends. However two of the calls, to c_common_type_for_mode and pushdecl, could equivalently be made to a langhook. This patch switches these to langhook calls. 2-stubs.diff This adds a new file that provides dummy implementations for all the routines mentioned in (1) that can't be turned into langhook calls. Putting these in one place means that Ada, java and fortran can be made to compile by simply li...

...and I don't know objective C very well in any case. :) Fortran, Java, and Ada support has not been tried at all, and are likely to be more work than objc. If you are familiar with GCC, adding support for the other GCC front-ends is not very difficult. It basically amounts to implementing the langhooks that are used to expand the language-specific tree nodes into the appropriate LLVM code. Of all of them, having G77 would be particularly nice, because it would allow us to run the rest of SpecFP, though f2c might be another option if it works very well (I've never tried it before). Long-ter...
