Also outstanding is that the return value setup for beginTransaction needs to be adjusted into the new block. I.e. we current generate
(set (reg eax) (call _ITM_beginTransaction)) (set (reg psuedo) (reg eax)) .Lrestart: // rest of tm block
This must be
(set (reg eax) (call _ITM_beginTransaction)) .Lrestart: (set (reg psuedo) (reg eax)) // rest of tm block
lest the register allocator do the wrong thing.
Thanks. -- Patrick.
