from <span class="vcard"><a class="email" href="mailto:caio.oliveira@intel.com" title="Caio Marcelo de Oliveira Filho <caio.oliveira@intel.com>"> <span class="fn">Caio Marcelo de Oliveira Filho</span></a>

<pre>I suspect this is <a href="https://gcc.gnu.org/bugzilla/show_bug.cgi?id=10676">https://gcc.gnu.org/bugzilla/show_bug.cgi?id=10676</a>. In our
struct we have a nested union that's unnamed. The tested GCC misses that
somehow.
struct value {
bool is_ssa;
union {
struct {
nir_ssa_def *def[NIR_MAX_VEC_COMPONENTS];
uint8_t component[NIR_MAX_VEC_COMPONENTS];
} ssa;
nir_deref_instr *deref;
};
};
The bug comments there suggests (1) adding extra set of braces around the .ssa
in the initializer. Other possible ways to fix are: (2) naming the union, or
(3) creating the temporary and then assigning to '*value' in the code. If we
have to do this, I think the more natural solution would be (3).
I don't have GCC 4.4 handy to test those three options though.</pre>
