Subject: nir: Split macro nir_foreach_function_with_impl out of nir_foreach_function_impl
X-Git-Tag: upstream/23.3.3~6339
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=fde6b51749a7b2ef6b3ecf7ecb34ef8d5813d3f0;p=platform%2Fupstream%2Fmesa.git

nir: Split macro nir_foreach_function_with_impl out of nir_foreach_function_impl

This macro nir_foreach_function_with_impl can be used when func and func->impl are both accessed in
foreach loop
