2013-08-15Add ToCStr method .with_c_str()Kevin Ballard-1/+1
.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().
2013-08-11auto merge of #8410 : luqmana/rust/mcpu, r=sanxiynbors-0/+1
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.
2013-08-11auto merge of #8421 : alexcrichton/rust/unnamed-addr, r=thestingerbors-0/+9
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!

the default, 'generic'.
2013-08-10auto merge of #8270 : dotdash/rust/ret_alloca_elim, r=pcwaltonbors-0/+2
When there is only a single store to the ret slot that dominates the load that gets the value for the "ret" instruction, we can elide the ret slot and directly return the operand of the dominating store instruction. This is the same thing that clang does, except for a special case that doesn't seem to affect us. Fixes #8238

2013-08-04Fix build issues once LLVM has been upgradedAlex Crichton-1/+2
* 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

2013-07-21Avoid blocks for static allocas and loading the closure environmentBjörn Steinbrink-0/+2
These blocks were required because previously we could only insert instructions at the end of blocks, but we wanted to have all allocas in one place, so they can be collapse. But now we have "direct" access the the LLVM IR builder and can position it freely. This allows us to use the same trick that clang uses, which means that we insert a dummy "marker" instruction to identify the spot at which we want to insert allocas. We can then later position the IR builder at that spot and insert the alloca instruction, without any dedicated block. The block for loading the closure environment can now also go away, because the function context now provides the toplevel block, and the translation of the loading happens first, so that's good enough. Makes the LLVM IR a bit more readable, saving a bunch of branches in the unoptimized code, which benefits unoptimized builds.
