The
scope(failure)
construct means that a try/catch statement is inserted into the function, this raises an error whenparams.useExceptions
is disabled. This might look less than ideal, however counter-intuitively this change makes it possible to compile the whole front-end with-fno-exceptions
.So the good news is, we could mark every function in the front-end as
nothrow
and it'd successfully compile.The downside is, that change requires hundreds-to-thousands of code changes everywhere at once.
I'd prefer to do the simplest thing for now and get
-fno-exceptions
working, then if someone finds the time to - or can automate - addingnothrow
everywhere in the compiler, then all the better later.@Geod24
