[Mesa-dev] [PATCH] R600/SI: allow 4 more input SGPRs to a shader

[Marek Olšák]

From: Marek Olšák <marek.olsak at amd.com>

Mesa needs one more SGPR, let's add 5 then, because it's a recurring issue.

This is silly. Why cannot Mesa specify the calling convention?
Now I have to break transform feedback to support ARB_draw_indirect until
this patch is released. Or I'll have to wait until the release and then
merge ARB_draw_indirect support.
