This patch changes how to specify ABI and link name of a native module.
Before:
native "cdecl" mod llvm = "rustllvm" {...}
After:
#[abi = "cdecl"]
#[link_name = "rustllvm"]
native mod llvm {...}
The old optional syntax for ABI and link name is no longer supported.
Fixes issue #547
There's no good reason to force them to be spilled anymore. Some
pieces of trans become more elegant this way, and less stack allocs
and load/stores are needed.
Issue #1021
Vectors are now similar to our old, pre-internal vectors, except that
they are uniquely owned, not refcounted.
Their name should probably change too, then. I've renamed them to vec
in the runtime, will do so throughout the compiler later.
While it is still technically possible to test stage 0, it is not part of any
of the main testing rules and maintaining xfail-stage0 is a chore. Nobody
should worry about how tests fare in stage0.
