|

|

* 1) We must guarantee that setjmp is called after allocating the builder
|
||
* and setting up b->debug (so that logging works) but before before any
|
||
* errors have a chance to occur.
|
||
*
|
||
* 2) While doing the SPIR-V -> NIR conversion, we need to be careful to
|
||
* ensure that all heap allocations happen through ralloc and are parented
|
||
* to the builder. This way they will get properly cleaned up on error.
|
||
*
|
||
* 3) We must ensure that _vtn_fail is never called while a mutex lock or a
|
||
* reference to any other resource is held with the exception of ralloc
|
||
* objects which are parented to the builder.
|
||
*
|
||
* So long as these two things continue to hold, we can easily longjmp back to

* spirv_to_nir(), clean up the builder, and return NULL.
