Readers pin the store and get the plain words, decoded from the frame when the plain copy is gone; one packer makes the frame of a store unused for a while, checks it by decoding it, and frees the plain copy. The lock is held for a few loads and stores only, never across a decode, an encode or a free. tests/spv_store_check.py walks a store through its states and runs four reader threads against a packer for three seconds, comparing every word they read.

"""Build and run tests/spv_store_check.c: runtime/spv_store.h, which keeps a shader's SPIR-V zstd-compressed while
|
|
nobody reads it (runtime/gfx_shader.c "SPIR-V at rest"). The check walks one store through pin, pack, decode and idle
|
|
again, and runs reader threads against a packer that compresses every store as soon as it is free: no reader may see
|
|
other words than the original, and every pin must be given back. Linked with the platform layer and libzstd.
