[Mesa-dev] [PATCH 0/9] spirv: Improve logging and error handling

[Jason Ekstrand]

This series has two objectives:

 1) Improve logging to provide more detail and provide hooks so we can
    plumb errors and warnings through to debug_report extensions.

 2) Improve error handling so that not all errors result in killing the
    process.  This is done by adding new spv_fail and spv_assert helpers
    which log the error and longjump back to a point where we can clean up
    and return NULL without crashing.

There is still quite a ways to go with error handling if we want to be able
to guarantee that we won't crash given an arbitrary stream of bytes.
However, this should at least be a step in the right direction.  There are
probably at least a couple of cases where I could have left an assert() as
an actual "kill the process" assert because it's testing for internal
consistency.  However, the vast majority of them are validation checks so
it seemed better to just search+replace them all and we can convert the few
that we want back to real asserts later.
