Hi,
The patch is preparatory for the patch2 - remove mode promotion for
pseudos.
The attachments are the patch diff and change log file.
Bootstrapped and tested on powerpc64le-linux and powerpc64-linux
(with both m32 and m64) with no regressions. Is this okay for trunk? Any
recommendations? Thanks a lot.
