2013-08-20auto merge of #8328 : alexcrichton/rust/llvm-head, r=brsonbors-3/+7
The first commit message is pretty good, but whomever reviews this should probably also at least glance at the changes I made in LLVM. I basically reorganized our pending patch queue to be a bit more organized and clearer in what needs to go where. After this, our queue would be: * Add the `no-split-stack` attribute * Add the `fixedstacksegment` attribute * Add split-stacks for arm android * Add split-stacks for arm linux * Add split stacks for mips Then there's a patch which I added to get rust to build at all on LLVM-head, and I'm not quite sure why it's there, but nothing seems to be crashing for now! (famous last words). Otherwise, I just updated code to reflect the changes I made in LLVM with the only major change being the advent of the new `no_split_stack` attribute. This is work towards #1226, but someone more familiar with the code should probably actually assign the attribute to the appropriate functions. Also as a bonus, I've verified that this closes #5774
2013-08-20Fix LLVM compilation issues and use the new attrsAlex Crichton-3/+7
This implements #[no_split_stack] and also changes #[fast_ffi] to using the new "fixedstacksegment" string attribute instead of integer attribute.

2013-08-11auto merge of #8410 : luqmana/rust/mcpu, r=sanxiynbors-1/+2
Adds `--target-cpu` flag which lets you choose a more specific target cpu instead of just passing the default, `generic`. It's more or less akin to `-mcpu`/`-mtune` in clang/gcc.

the default, 'generic'.
2013-08-09Implement an `address_insignificant` attributeAlex Crichton-0/+4
This can be applied to statics and it will indicate that LLVM will attempt to merge the constant in .data with other statics. I have preliminarily applied this to all of the statics generated by the new `ifmt!` syntax extension. I compiled a file with 1000 calls to `ifmt!` and a separate file with 1000 calls to `fmt!` to compare the sizes, and the results were: fmt 310k ifmt (before) 529k ifmt (after) 202k This now means that ifmt! is both faster and smaller than fmt!, yay!
2013-08-04Fix build issues once LLVM has been upgradedAlex Crichton-10/+1
* LLVM now has a C interface to LLVMBuildAtomicRMW * The exception handling support for the JIT seems to have been dropped * Various interfaces have been added or headers have changed

2013-05-29Refactor optimization pass handling.James Miller-45/+3
Refactor the optimization passes to explicitly use the passes. This commit just re-implements the same passes as were already being run. It also adds an option (behind `-Z`) to run the LLVM lint pass on the unoptimized IR.

2013-04-05rustllvm: Only initialize command-line arguments onceTim Chevalier-4/+12
In my WIP on rustpkg, I was calling driver code that calls LLVMRustWriteOutputFile more than once. This was making LLVM unhappy, since that function has code that initializes the command-line options for LLVM, and I guess you can't do that more than once. So, check if they've already been initialized.

2013-03-13Revamp foreign code not to consider the Rust modes. This requiresNiko Matsakis-2/+2
adjusting a few foreign functions that were declared with by-ref mode. This also allows us to remove by-val mode in the near future. With copy mode, though, we have to be careful because Rust will implicitly pass somethings by pointer but this may not be the C ABI rules. For example, rust will pass a struct Foo as a Foo*. So I added some code into the adapters to fix this (though the C ABI rules may put the pointer back, oh well). This patch also includes a lint mode for the use of by-ref mode in foreign functions as the semantics of this have changed.
