Since all tests are compiled with LTO effectively in Emscripten this commit
disables optimizations to hopefully squeeze some more time out of the CI
builders.
Closes #48826

LLVM currently doesn't remove the "bypass if argument is zero" assembly inside branches where the value is known to be non-zero, pessimizing code that uses uN::leading_zeros
|
|
|
|
Similarly to the simd intrinsics.

This commit removes pretty-expanded from all tests that wind up calling panic!
one way or another now that its internals are unstable.
|
|
|
|
Now that features must be declared expanded source often does not compile.
This adds 'pretty-expanded' to a bunch of test cases that still work.

If you define lang items in your crate, add `#[feature(lang_items)]`.
If you define intrinsics (`extern "rust-intrinsic"`), add
`#[feature(intrinsics)]`.
Closes #12858.

Exposing ctpop, ctlz, cttz and bswap as taking signed i8/i16/... is just
exposing the internal LLVM names pointlessly (LLVM doesn't have "signed
integers" or "unsigned integers", it just has sized integer types
with (un)signed *operations*).
These operations are semantically working with raw bytes, which the
unsigned types model better.

From the 0.10 changelog:
* The inner attribute syntax has changed from `#[foo];` to `#![foo]`.
|
|
This commit shreds all remnants of libextra from the compiler and standard
distribution. Two modules, c_vec/tempfile, were moved into libstd after some
cleanup, and the other modules were moved to separate crates as seen fit.
Closes #8784
Closes #12413
Closes #12576

This was previously implemented, and it just needed a snapshot to go through
|
|
|
|
They've been replaced by putting the name on the extern block.
#[abi = "foo"]
goes to
extern "foo" { }
Closes #9483.

This commit fixes all of the fallout of the previous commit which is an attempt
to refine privacy. There were a few unfortunate leaks which now must be plugged,
and the most horrible one is the current `shouldnt_be_public` module now inside
`std::rt`. I think that this either needs a slight reorganization of the
runtime, or otherwise it needs to just wait for the external users of these
modules to get replaced with their `rt` implementations.
Other fixes involve making things pub which should be pub, and otherwise
updating error messages that now reference privacy instead of referencing an
"unresolved name" (yay!).
|
|
|
|
Place `pub` or `priv` on individual items instead.

I believe this patch incorporates all expected syntax changes from extern
function reform (#3678). You can now write things like:
extern "<abi>" fn foo(s: S) -> T { ... }
extern "<abi>" mod { ... }
extern "<abi>" fn(S) -> T
The ABI for foreign functions is taken from this syntax (rather than from an
annotation). We support the full ABI specification I described on the mailing
list. The correct ABI is chosen based on the target architecture.
Calls by pointer to C functions are not yet supported, and the Rust type of
crust fns is still *u8.

Adds support for the llvm.bswap.i{8,16,32} intrinsics, which swaps the
byte order from little endian to big endian, or the reverse.
|
|
Adds support for the llvm.ctpop, llvm.ctlz and llvm.cttz intrinsics.
