2013-08-20auto merge of #8328 : alexcrichton/rust/llvm-head, r=brsonbors-0/+1
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-0/+1
This implements #[no_split_stack] and also changes #[fast_ffi] to using the new "fixedstacksegment" string attribute instead of integer attribute.

2013-08-09Implement an `address_insignificant` attributeAlex Crichton-0/+1
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!

2013-07-21Avoid blocks for static allocas and loading the closure environmentBjörn Steinbrink-0/+1
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.

This allows parallel usage of the rustc library
2013-05-29Further refactor optimization pass handlingJames Miller-98/+2
This refactors pass handling to use the argument names, so it can be used in a similar manner to `opt`. This may be slightly less efficient than the previous version, but it is much easier to maintain. It also adds in the ability to specify a custom pipeline on the command line, this overrides the normal passes, however. This should completely close #2396.

2013-05-29Refactor optimization pass handling.James Miller-0/+102
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.
