2013-08-17Fix warnings in testsErick Tryzelaar-1/+1
2013-08-16auto merge of #8532 : kballard/rust/cstr-cleanup, r=ericktbors-4/+4

2013-08-15Add ToCStr method .with_c_str()Kevin Ballard-4/+4
.with_c_str() is a replacement for the old .as_c_str(), to avoid unnecessary boilerplate. Replace all usages of .to_c_str().with_ref() with .with_c_str().

2013-08-06vec: use `offset_inbounds` for iteratorsDaniel Micay-1/+20
This allows LLVM to optimize vector iterators to an `getelementptr` and `icmp` pair, instead of `getelementptr` and *two* comparisons.

2013-08-04std and rustc: explicitly pass c strings to c functionsErick Tryzelaar-47/+54
When strings lose their trailing null, this pattern will become dangerous: let foo = "bar"; let foo_ptr: *u8 = &foo[0]; Instead we should use c_strs to handle this correctly.

2013-07-18auto merge of #7857 : blake2-ppc/rust/fix-test-warnings, r=alexcrichtonbors-3/+4
Fix warnings that only show up when compiling the tests for libstd, libextra and one in librusti. Only trivial changes.

2013-07-08update ptr intrinsics and rewrite vec routines to be more correct.Niko Matsakis-0/+50
In particular, it is not valid to go around passing uninitialized or zero'd memory as arguments. Rust should generally be free to assume that the arguments it gets are valid input values, but the output of intrinsics::uninit() and intrinsics::init() are not (e.g., an @T is just null, leading to an error if we should try to increment the ref count).

2013-06-06libc: omit memcpy, memmove and memsetDaniel Micay-23/+1
LLVM provides these functions as intrinsics, and will generate calls to libc when appropriate. They are exposed in the `ptr` module as `copy_nonoverlapping_memory`, `copy_memory` and `set_memory`.
