I think I figured out the problem.
As commented on DECL_RESOURCE_FUNC macro, the RESOURCE_VAR inline function
is not type safe, and stuff that's not a ir_variable is wrongly being casted
into it.
This patch seems to do the trick, but I'm not 100% sure.
Yep it is correct, just like with _mesa_longest_attribute_name_length. Not sure
why I did not manage to hit this.

I think we should invest the time to make RESOURCE_VAR and friends more
robust, by adding assertions that the types are indeed correct. (Replace
DECL_RESOURCE_FUNC helper macro by manually written code if necessary.)
This sort of bugs is hard to find otherwise.
I agree, current way is too fragile. IMO a type template would be best
solution. Maybe first just adding the assert for the correct type is good
start.

mesa: refactor active attrib queries for glGetProgramiv
Main motivation here is to get rid of iterating IR and
encapsulate queries within program resources.
No functional changes.
Piglit tests calling the modified functionality:
- gl-get-active-attrib-returns-all-inputs
- glsl-1.50-get-active-attrib-array
- getactiveattrib
[...]
Piglit `getactiveattrib 110` test started to randomly fail on llvmpipe:
$ for i in `seq 1 100`; do .../piglit/bin/getactiveattrib 110 -auto -fbo; done
PIGLIT: {result: pass }
PIGLIT: {result: pass }
PIGLIT: {result: pass }
PIGLIT: {result: pass }
PIGLIT: {result: pass }
PIGLIT: {result: pass }
PIGLIT: {result: pass }
PIGLIT: {result: pass }
Mesa: User error: GL_INVALID_VALUE in glGetActiveAttrib(index)
Failing shader:
attribute vec4 vertex;
attribute vec2 alternate;
uniform bool use_alternate;
void main() {
gl_Position = vertex;
if (use_alternate) gl_Position = alternate.xyxy;
}
Attribute `alternate' listed multiple times in active list.
PIGLIT: {result: fail }
PIGLIT: {result: pass }
PIGLIT: {result: pass }
When I revert 'a563689' all is smooth, again.
And likewise, if I revert a563689 it passes consistently.
