In doing some testing we’ve noticed that trying to draw pixel aligned textures does not work very well with linear filtering in llvmpipe.Here’s an example of the problem.Imagine wanting to paint a 100x100 texture. After being scaled by 100 the texture coordinates will end up as:0.5, 1.5, 2.5, 3.5,

This adds code that is basically the same as the code in smod, div and idiv.
However, unlike idiv we return -1.
diff --git a/src/gallium/auxiliary/gallivm/lp_bld_tgsi_action.c
b/src/gallium/auxiliary/gallivm/lp_bld_tgsi_action.c

Do you mind fixing up the language to match what you're looking for
and committing it?
Thanks,
