Hi,
As noted in #6804, a pattern that contains `NaN` will never match because `NaN != NaN`. This adds a warning for such a case. The first commit handles the basic case and the second one generalizes it to more complex patterns using `walk_pat`.
Remove directive, if present, from CFG_RUSTC_FLAGS.

Fix#7898.
(One alternative tack is to build up distinct CFG_TEST_RUSTC_FLAGS
alongside CFG_RUSTC_FLAGS; but currently debug is the only --cfg flag
ever added to CFG_RUSTC_FLAGS; the other contents of CFG_RUSTC_FLAGS
are a mix of -Z flags and a few other switches like O, which seem to
make sense to propogate to the tests.)
Infers type of constants used as discriminants and ensures they are
integral, instead of forcing them to be a signed integer.
Also, stores discriminant values as uint instead of int interally and
deals with related fallout.
Fixes issue #7994
First, clean up the uses of "None" and "Some" to always use consistent title case matching the variant names.
Add .chain_mut_ref() which is a missing method. A use case example for this method is extraction of an optional value from an Option\<Container\> value.
Hello,
I made a tiny change to `tidy.py` so that it uses a regexp to find `// NOTE` comments. I could not find an easy way to write an automated test for this but if this is needed and possible I'd be happy to write one.
Please note that it also removes extra empty lines that appear after each of these warnings (I believe that there were not wanted).
On the performance side, `make tidy` is now a bit slower (running it 10 times in a row takes 71s on my machine, 65s before) but I don't think that it is performance sensitive.
Thanks!
This is a cleanup pull request that does:
* removes `os::as_c_charp`
* moves `str::as_buf` and `str::as_c_str` into `StrSlice`
* converts some functions from `StrSlice::as_buf` to `StrSlice::as_c_str`
* renames `StrSlice::as_buf` to `StrSlice::as_imm_buf` (and adds `StrSlice::as_mut_buf` to match `vec.rs`.
* renames `UniqueStr::as_bytes_with_null_consume` to `UniqueStr::to_bytes`
* and other misc cleanups and minor optimizations
The code to build the transmute intrinsic currently makes the invalid
assumption that if the in-type is non-immediate, the out-type is
non-immediate as well. But this is wrong, for example when transmuting
[int, ..1] to int. So we need to handle this fourth case as well.

This allows for control over the section placement of static, static
mut, and fn items. One caveat is that if a static and a static mut are
placed in the same section, the static is declared first, and the static
mut is assigned to, the generated program crashes. For example:
#[link_section=".boot"]
static foo : uint = 0xdeadbeef;
#[link_section=".boot"]
static mut bar : uint = 0xcafebabe;
Declaring bar first would mark .bootdata as writable, preventing the
crash when bar is written to.
This just redoes various parts of workcache to support context-cloning (eventually quite crudely, via ARCs), the absence of which was blocking rustpkg from being able to use it. Better versions of this are possible (notably removing the ARCs on everything except the database) but it ought to work well enough for now.
