Hi,

This series makes the 'if' conditions less liberal, by formalizing a simple
expression tree based on bare boolean logic of configure option identifiers.

(this will allow to express conditions in Rust in my QAPI-Rust PoC series, but
it is worth a standalone post)

This is based on John Snow QAPI cleanup branch:
https://gitlab.com/jsnow/qemu/-/tree/python-qapi-cleanup-pt6

thanks

Marc-André Lureau (9):
  qapi: replace List[str] by IfCond
  qapi: move gen_if/gen_endif to IfCond
  qapi: start building an 'if' predicate tree
  qapi: introduce IfPredicateList and IfAny
  qapi: add IfNot
  qapi: normalize 'if' condition to IfPredicate
  qapi: convert 'if' C expressions to literal form
  qapi: make 'if' condition strings simple identifiers
