Subject: gallium: add shadow 1D and 2D array samplers to TGSI
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d8452a0be810d7176b0cbfe6632fc0f8016b5733;p=mesa.git

gallium: add shadow 1D and 2D array samplers to TGSI

And filling in all the switch statements in auxiliary. Mostly untested.
