This makes passing them around cheaper. There is now a table (see
front/codemap.rs) that is needed to transform such an uint into an
actual filename/line/col location.
Also cleans up the span building in the parser a bit.
symbols because of an Object.o in a .a and one outside. A similar
problem happens for the non-shared part of libpthread.
This patch moves the -whole-archive/-no-whole-archive to include just the
llvm libs.
I think just about every type can be used as a block result now. There's quite
a proliferation of tests here, but they all test slightly different things and
some are split out to remain XFAILed. The tests of generic vectors are still
XFAILed because generic aliased boxes still don't work in general.
This was removed because of the repetition, but doing single-byte
reads in terms of read_bytes (which allocates a vec) is needlessly
slow. This change speeds up parsing by 22%.
(Eventually, we won't be able to escape handling the buffering in the
stdlib itself.)
Nicer parsing of self-calls (expr_self_method nodes inside expr_call
nodes, rather than a separate expr_call_self) makes typechecking
tractable. We can now write self-calls that take arguments and return
values (see: test/run-pass/obj-self-*.rs).
It was creating non-multiple-of-four section sizes, which, for some
reason, presumably by LLVM, were clipped, rather than padded, to be a
multiple of four.
It's still sketchy. I added a typestate annotation field to statements
tagged stmt_decl or stmt_expr, because a stmt_decl statement has a typestate
that's different from that of its child node. This necessitated trivial
changes to a bunch of other files all over to the compiler. I also added a
few small standard library functions, some of which I didn't actually end
up using but which I thought might be useful anyway.
The last few pieces of the hack that lets us use trans.trans_call() to
translate self-calls, plus a fix for the parser buy that was
preventing self-call expressions from getting past parsing.
test/run-pass/obj-self.rs works now (as in it actually prints "hi!"
twice!).
