It almost seems like you want a hash of the program key - and maybe a
file containing a printed copy of the key so you can identify which
program is which.
Alternatively, one could use the address of the key with %p to obtain
a unique identifier. That's easy and should solve the problem.
Unfortunately, the pointer is non-deterministic so comparing from one
run to another is going to be hard. A quick-and-dirty hash of the key
might work though.
Why not use the same path/file prefix & hash as what
MESA_SHADER_DUMP_PATH feature does?
Then it's easy to match saved GLSL source to the optimizer output.
(Windows driver uses same shader source hash for identifying everything
from GLSL source to intermediate representation to shader asm and I
think that's the only sane way.)
