Subject: nir/builder: Generate the alu helpers directly in python
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=fc58cb543fe2430576216680c4f6a55ec22b937e;p=mesa.git

nir/builder: Generate the alu helpers directly in python

There's no reason for having a macro *and* a python generator.  We can
easily just do the whole thing in python.  This has the advantage that we
are no longer definining ALU# macros which conflict with the ones in
brw_fs_builder.h.
