2013-12-10Make crate hash stable and externally computable.Jack Moffitt-0/+670
This replaces the link meta attributes with a pkgid attribute and uses a hash of this as the crate hash. This makes the crate hash computable by things other than the Rust compiler. It also switches the hash function ot SHA1 since that is much more likely to be available in shell, Python, etc than SipHash. Fixes #10188, #8523.
2013-12-09Implement LTOAlex Crichton-1/+10
This commit implements LTO for rust leveraging LLVM's passes. What this means is: * When compiling an rlib, in addition to insdering foo.o into the archive, also insert foo.bc (the LLVM bytecode) of the optimized module. * When the compiler detects the -Z lto option, it will attempt to perform LTO on a staticlib or binary output. The compiler will emit an error if a dylib or rlib output is being generated. * The actual act of performing LTO is as follows: 1. Force all upstream libraries to have an rlib version available. 2. Load the bytecode of each upstream library from the rlib. 3. Link all this bytecode into the current LLVM module (just using llvm apis) 4. Run an internalization pass which internalizes all symbols except those found reachable for the local crate of compilation. 5. Run the LLVM LTO pass manager over this entire module 6a. If assembling an archive, then add all upstream rlibs into the output archive. This ignores all of the object/bitcode/metadata files rust generated and placed inside the rlibs. 6b. If linking a binary, create copies of all upstream rlibs, remove the rust-generated object-file, and then link everything as usual. As I have explained in #10741, this process is excruciatingly slow, so this is *not* turned on by default, and it is also why I have decided to hide it behind a -Z flag for now. The good news is that the binary sizes are about as small as they can be as a result of LTO, so it's definitely working. Closes #10741 Closes #10740

2013-10-05auto merge of #9250 : erickt/rust/num, r=ericktbors-1/+1
This PR solves one of the pain points with c-style enums. Simplifies writing a fn to convert from an int/uint to an enum. It does this through a `#[deriving(FromPrimitive)]` syntax extension. Before this is committed though, we need to discuss if `ToPrimitive`/`FromPrimitive` has the right design (cc #4819). I've changed all the `.to_int()` and `from_int()` style functions to return `Option<int>` so we can handle partial functions. For this PR though only enums and `extra::num::bigint::*` take advantage of returning None for unrepresentable values. In the long run it'd be better if `i64.to_i8()` returned `None` if the value was too large, but I'll save this for a future PR. Closes #3868.
2013-10-04rustc: Use static strings in a few literalsblake2-ppc-1/+1
Avoid allocating extra copies of strings by using "" instead of ~"" for the debug options list and for the `time` function. This is a small change, but it is in a path that's always executed.

2013-10-01remove the `float` typeDaniel Micay-1/+0
It is simply defined as `f64` across every platform right now. A use case hasn't been presented for a `float` type defined as the highest precision floating point type implemented in hardware on the platform. Performance-wise, using the smallest precision correct for the use case greatly saves on cache space and allows for fitting more numbers into SSE/AVX registers. If there was a use case, this could be implemented as simply a type alias or a struct thanks to `#[cfg(...)]`. Closes #6592 The mailing list thread, for reference: https://mail.mozilla.org/pipermail/rust-dev/2013-July/004632.html

2013-09-04auto merge of #8875 : alexcrichton/rust/fix-inner-static-library-bug, r=huonwbors-1/+2
These commits fix bugs related to identically named statics in functions of implementations in various situations. The commit messages have most of the information about what bugs are being fixed and why. As a bonus, while I was messing around with name mangling, I improved the backtraces we'll get in gdb by removing `__extensions__` for the trait/type being implemented and by adding the method name as well. Yay!

2013-09-02Remove __extensions__ in names for a "pretty name"Alex Crichton-1/+2
As with the previous commit, this is targeted at removing the possibility of collisions between statics. The main use case here is when there's a type-parametric function with an inner static that's compiled as a library. Before this commit, any impl would generate a path item of "__extensions__". This changes this identifier to be a "pretty name", which is either the last element of the path of the trait implemented or the last element of the type's path that's being implemented. That doesn't quite cut it though, so the (trait, type) pair is hashed and again used to append information to the symbol. Essentially, __extensions__ was removed for something nicer for debugging, and then some more information was added to symbol name by including a hash of the trait being implemented and type it's being implemented for. This should prevent colliding names for inner statics in regular functions with similar names.

2013-08-19Make supertrait methods callable on object types.Michael Sullivan-2/+12
This requires changes to method search and to codegen. We now emit a vtable for objects that includes methods from all supertraits. Closes #4100. Also, actually populate the cache for vtables, and also key it by type so that it actually works.

2013-08-11typeck: Modify method resolution to use new object adjustments, andNiko Matsakis-3/+2
to favor inherent methods over extension methods. The reason to favor inherent methods is that otherwise an impl like impl Foo for @Foo { fn method(&self) { self.method() } } causes infinite recursion. The current change to favor inherent methods is rather hacky; the method resolution code is in need of a refactoring.
