Subject: gallivm: use common code to select texel type
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=727bb217be680ba7de4e8821fbe409921952cd93;p=mesa.git

gallivm: use common code to select texel type

This was suggested by Roland, and fixes stencil images.

Fixes:
dEQP-VK.renderpass.dedicated_allocation.formats.d24_unorm_s8_uint.*
dEQP-VK.renderpass.dedicated_allocation.formats.d32_sfloat_s8_uint.*
