2017-02-06Delete the `mk` folderAlex Crichton-71/+0
This commit deletes the old build system located in the `mk` folder as it's now been obsoleted for two cycles and is replaced by rustbuild.
2016-08-06Merge branch 'master' into issue-30961Cameron Hart-1/+1
2016-08-03remove the ExecutionEngine bindingAriel Ben-Yehuda-1/+1
the code has no tests and will just bitrot by itself. this is a [breaking-change]
2016-07-24Pass -DLLVM_RUSTLLVM to compile against rust llvm fork.Cameron Hart-0/+6
If using system llvm don't try use modifications made in the fork.
2016-04-09Implement feature extraction from `TargetMachine`Andrea Canciani-0/+4
Add the `LLVMRustHasFeature` function to check whether a `TargetMachine` has a given feature.
2015-07-10trans: Use LLVM's writeArchive to modify archivesAlex Crichton-1/+2
We have previously always relied upon an external tool, `ar`, to modify archives that the compiler produces (staticlibs, rlibs, etc). This approach, however, has a number of downsides: * Spawning a process is relatively expensive for small compilations * Encoding arguments across process boundaries often incurs unnecessary overhead or lossiness. For example `ar` has a tough time dealing with files that have the same name in archives, and the compiler copies many files around to ensure they can be passed to `ar` in a reasonable fashion. * Most `ar` programs found do **not** have the ability to target arbitrary platforms, so this is an extra tool which needs to be found/specified when cross compiling. The LLVM project has had a tool called `llvm-ar` for quite some time now, but it wasn't available in the standard LLVM libraries (it was just a standalone program). Recently, however, in LLVM 3.7, this functionality has been moved to a library and is now accessible by consumers of LLVM via the `writeArchive` function. This commit migrates our archive bindings to no longer invoke `ar` by default but instead make a library call to LLVM to do various operations. This solves all of the downsides listed above: * Archive management is now much faster, for example creating a "hello world" staticlib is now 6x faster (50ms => 8ms). Linking dynamic libraries also recently started requiring modification of rlibs, and linking a hello world dynamic library is now 2x faster. * The compiler is now one step closer to "hassle free" cross compilation because no external tool is needed for managing archives, LLVM does the right thing! This commit does not remove support for calling a system `ar` utility currently. We will continue to maintain compatibility with LLVM 3.5 and 3.6 looking forward (so the system LLVM can be used wherever possible), and in these cases we must shell out to a system utility. All nightly builds of Rust, however, will stop needing a system `ar`.
2015-05-19mk: Fix MSVC build for rustllvm.libAlex Crichton-7/+21
This commit updates the rustllvm.mk file with the necessary flags and such to build rustllvm.lib with cl.exe instead of gcc. Some comments can be found in the commit itself.
2015-04-27mk: Remove a bunch of unused directivesAlex Crichton-2/+0
2014-12-11Add LLVM ExecutionEngine APIMurarth-1/+2
2014-02-02Remove VPATH usage in MakefilesAlex Crichton-1/+1
This is just messing up all the doc dependencies because of such similar directory names and file names. Closes #11422
2014-01-26Refactor the build system for easily adding cratesAlex Crichton-1/+2
Before this patch, if you wanted to add a crate to the build system you had to change about 100 lines across 8 separate makefiles. This is highly error prone and opaque to all but a few. This refactoring is targeted at consolidating this effort so adding a new crate adds one line in one file in a way that everyone can understand it.
2013-12-06Link rustllvm statically, and distribute a static snapshotAlex Crichton-6/+2
In order to keep up to date with changes to the libraries that `llvm-config` spits out, the dependencies to the LLVM are a dynamically generated rust file. This file is now automatically updated whenever LLVM is updated to get kept up-to-date. At the same time, this cleans out some old cruft which isn't necessary in the makefiles in terms of dependencies. Closes #10745 Closes #10744

2013-05-29Refactor optimization pass handling.James Miller-1/+1
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.
