[PATCH 1/8] parloops: Copy target and optimizations when creating a function clone

[Andre Vieira (lists) via Gcc-patches]

SVE simd clones require to be compiled with a SVE target enabled or the 
argument types will not be created properly. To achieve this we need to 
copy DECL_FUNCTION_SPECIFIC_TARGET from the original function 
declaration to the clones.  I decided it was probably also a good idea 
to copy DECL_FUNCTION_SPECIFIC_OPTIMIZATION in case the original 
function is meant to be compiled with specific optimization options.

gcc/ChangeLog:

        * tree-parloops.cc (create_loop_fn): Copy specific target and
        optimization options to clone.diff --git a/gcc/tree-parloops.cc b/gcc/tree-parloops.cc
