Subject: aarch64: Expand %<w> correctly according to mode iterator
X-Git-Tag: basepoints/gcc-13~5506
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a5e78ee60cd54dcceb9e7cfa42edd0c29c280f5c;p=thirdparty%2Fgcc.git

aarch64: Expand %<w> correctly according to mode iterator

Pattern "*extend<SHORT:mode><GPI:mode>2_aarch64" is duplicated
from the corresponding zero_extend pattern, however %<w> needs
to be expanded according to its mode iterator because the smov
instruction is different to umov.

	(*extend<SHORT:mode><GPI:mode>2_aarch64): Use %<GPI:w>0.
