Might I suggest to instead of
case GIMPLE_ASM:
gcc_unreachable ();
use
case GIMPLE_ASM:
sorry ("asm statements not allowed in transactions");
? It's not a compiler but a user error (well, usually).
Btw, what you really want is some simple IPA propagation of the various
transaction attributes similar to how we handle pure/const.
