... previously the exit condition was treated the same as the loop
condition (which is the inverse condition of the exit condition). Now
this is corrected.
gcc/rust/ChangeLog:
* backend/rust-compile-expr.cc (CompileExpr::visit): Properly formulate
exit condition when compiling while loops.
Signed-off-by: Zixing Liu <[email protected]>
Tested on x86_64-pc-linux-gnu, committed on master.
