At the LLVM Bay Area meetup this question came up
“What does -O0 mean to you?”
A. No transformations, straight translation
B. Transformations that don’t inhibit debuggability
C. B + no undefined behavior
D. Something else, explain
#Cplusplus #Programming #CppPolls
Well, it’s a chicken and egg problem… -O0 can’t improve without breaking GDB, while GDB has no incentive to improve until -O0 improves…
