58 /** Fail SPIR-V parsing
60 * This function logs an error and then bails out of the shader compile using
61 * longjmp. This being safe relies on two things:
63 * 1) We must guarantee that setjmp is called after allocating the builder
64 * and setting up b->debug (so that logging works) but before before any
65 * errors have a chance to occur.
67 * 2) While doing the SPIR-V -> NIR conversion, we need to be careful to
68 * ensure that all heap allocations happen through ralloc and are parented
69 * to the builder. This way they will get properly cleaned up on error.
71 * 3) We must ensure that _vtn_fail is never called while a mutex lock or a
72 * reference to any other resource is held with the exception of ralloc
73 * objects which are parented to the builder.
75 * So long as these two things continue to hold, we can easily longjmp back to
76 * spirv_to_nir(), clean up the builder, and return NULL.
