In clear_depth_stencil() stencil_surf is defined but not initiaized.
Then in the same function if stencil_mask is calculated and if != 0
stencil_surf is initialized.
But blorp_clear_stencil_as_rgba() access stencil_surf before checking
stencil_mask, what could cause a read of a uninitialized valued.
clear_depth_stencil()
struct blorp_surf stencil_surf;
...
uint8_t stencil_mask = clear_stencil && stencil_res ? 0xff : 0;
if (stencil_mask) {
...
iris_blorp_surf_for_resource(&stencil_surf);
}
...
blorp_clear_depth_stencil(stencil_mask, stencil_surf)
blorp_clear_stencil_as_rgba(stencil_mask, stencil)
if (surf->surf->format ...)
....
Just inverting the order and checking stencil_mask first in
blorp_clear_stencil_as_rgba() fixes the issue.
