From: Roland Scheidegger <srol...@vmware.com> This partly reverts 6ace2e41da7dded630d932d03bacb7e14a93d47a. Apparently with GL_MESA_texture_array fixed-function texturing with texture arrays is possible, and hence we have to handle TXP. (Though noone seems to know the semantics, softpipe now does what it did before, which is to NOT project the array coord, llvmpipe for instance however indeed does project the array coord. Unlike before it will project the comparison coord for shadow1d array, as that clearly was an error.) This fixes https://bugs.freedesktop.org/show_bug.cgi?id=61828. --- src/gallium/auxiliary/tgsi/tgsi_exec.c | 14 +++++++++++--- 1 file changed, 11 insertions(+), 3 deletions(-)
