<pre>GCC issues the following warning in my build:
In file included from ../../SOURCE/master/src/compiler/glsl_types.h:29:0,
from ../../SOURCE/master/src/compiler/nir_types.h:36,
from ../../SOURCE/master/src/compiler/nir/nir.h:39,
from
../../SOURCE/master/src/compiler/nir/nir_linking_helpers.c:24:
../../SOURCE/master/src/compiler/nir/nir_linking_helpers.c: In function
‘remap_slots_and_components’:
../../SOURCE/master/src/compiler/nir/nir_linking_helpers.c:286:63: warning:
ordered comparison of pointer with integer zero [-Wextra]
assert(remap[var->data.location - VARYING_SLOT_VAR0] >= 0);
^
I looked at the code, and remap is declared as "struct varying_loc
(*remap)[4]". It is comparing that a pointer to an array of 4 structures is >=
0. I'm not sure what the original intention was, but this tautology isn't
doing it.</pre>
