[Mesa-dev] swrast gallium provider doesn't work on Solaris SPARC (Mesa 20 with LLVM 10)

[Petr Sumbera]

Seems to be related to:

llvmpipe: switch to NIR by default

https://github.com/mesa3d/mesa/commit/e6b2af56cb037e3174d049478e0ad7c7715780e4#diff-ca9de5cfd0347994dacc6eca9816d334

Following helps me as workaround:

--- a/src/gallium/drivers/llvmpipe/lp_screen.c
+++ b/src/gallium/drivers/llvmpipe/lp_screen.c
@@ -434,8 +434,10 @@ llvmpipe_get_shader_param(struct pipe_screen *screen,
           struct llvmpipe_screen *lscreen = llvmpipe_screen(screen);
           if (lscreen->use_tgsi)
              return PIPE_SHADER_IR_TGSI;
+#if !defined(__sparc__)
           else
              return PIPE_SHADER_IR_NIR;
+#endif
        }

        switch (param) {

---

Any idea?
