This comes with a terminology change. All linkage-symbols are 'extern'
now, including rust syms in other crates. Some extern ABIs are
merely "foreign". The term "native" is retired, not clear/useful.
What was "crust" is now "extern" applied to a _definition_. This
is a bit of an overloading, but should be unambiguous: it means
that the definition should be made available to some non-rust ABI.
And replace trans::common::block_parent with option<block>. To handle
the recursive self-reference in the block_ class, I had to add a
newtype-like enum "block" which is equivalent to @block_ -- which due
to an interaction with borrowck, resulted in having to change a few
functions in trans::base to take their block argument in ++ mode,
irritatingly enough (but not that irritatingly, since we're supposed to
get rid of modes).
This means GEPi now takes a list of uints. Apologies in advance
if this is hard to rebase against, but it gets rid of many a cast :-)
Also modernized some for loops here and there.
As per Issue #1193. Closes#1193.
I had to rename a few variables ("info" and "epsilon") to avoid
clashing with in-scope constants, which is responsible for all the
changes other than resolve and issue-1193.rs.
Classes can have ty params now. So can methods inside classes.
That was probably true before, but now it should still work if you
call methods in a class that's defined in a different crate. Yay!
get_with_default (nee from_maybe) => get_default
with_option (nee maybe) => map_default
with_option_do (nee may) => iter
As per discussion of 21be1379d5
Most could use the each method, but because of the hack used to
disambiguate old- and new-style loops, some had to use vec::each.
(This hack will go away soon.)
Issue #1619
from_maybe => get_with_default
maybe => with_option
may => with_option_do
I know these names are kind of ridiculous, but it's the best I could think of.
Feel free to bikeshed. Closes#2081
1. Enforce mutability declarations on class fields. Don't allow any
mutation of class fields not declared as mutable (except inside the
constructor).
2. Handle classes correctly in shape (treat classes like records).
The code is somewhat invasive, but it seems hard to do this in a
clean way, since the design itself involves a bunch of 'action
at a distance'.
