34f7364332 rustc_llvm: Tweak how initialization is performed
Refactor a bit to have less repetition and #[cfg] and try to bury it all inside
of a macro.

d03712977d mk: fix some undefined variable warnings
Some of this is scary stuff. Probably time to lint against this.

Found with `make --warn-undefined-variables`.

04f9a3f8fe mk: Use the right llvmdeps.rs file for cross build
It looks like  accidentally switched the llvmdeps file from the target to
the host by accident, so be sure to use the right llvmdeps file which is built
for the target when building rustc_llvm

7bd69f2248 Better support for --llvm-root.
This handles cases when the LLVM used isn't configured will the 'usual'
targets. Also, cases where LLVM is shared are also handled (ie with
`LD_LIBRARY_PATH` etc).

876c33051a Escape some variables in llvm.mk
The important one is $(MAKE).  make handles recipes containing the
literal string "$(MAKE)" specially, so it is important to make sure it
isn't evaluated until recipe invocation time.

913fe6dbe9 add support for non-standard name of stdc++ library
it makes rustc compatible with gcc installation that are using
`--program-transform-name' configure flag (on OpenBSD for example).

- detects at configure the name of stdc++ library on the system

- use the detected name in llvm makefile (with enable-static-stdcpp),
  and pass it to mklldeps.py

- generate mklldeps.rs using this detected name

note that CFG_STDCPP_NAME is about stdc++ name, not about libc++. If
using libc++, the default name will be `stdc++', but it won't be used
when linking.

a4ef308473 mk: Add the ability to depend on native LLVM tools
The compiler will require that `llvm-ar.exe` be available for MSVC-targeting
builds (more comments on this soon), so this commit adds support for targets to
depend on LLVM tools. The `core` library for MSVC depends on `llvm-ar.exe` which
will be copied into place for the target before the compiler starts to run.

Note that these targets all depend on `llvm-config.exe` to ensure that they're
built before they're attempted to be copied.

b56d47cc80 mk: Enable building LLVM targeting MSVC
This commit modifies the makefiles to enable building LLVM with cmake and Visual
Studio to generate an LLVM that targets MSVC. Rust's configure script requires
cmake to be installed when targeting MSVC and will configure LLVM with cmake
instead of the normal `./configure` script LLVM provides. The build will then
run cmake to execute the build instead of the normal `make`.

Currently `make clean-llvm` isn't supported on MSVC as I can't figure out how to
run a "clean" target for the Visual Studio files.

ee258c548f mk: Fix native LLVM deps for cross-host builds
We use a script called `mklldeps.py` to run `llvm-config` to generate a list
of LLVM libraries and native dependencies needed by LLVM, but all cross-compiled
LLVM builds were using the *host triple's* `llvm-config` instead of the
*target's* `llvm-config`. This commit alters this to require the right
`llvmdeps.rs` to be generated which will run the correct `llvm-config`.

de52403295 Avoid passing -L "" to rustc.
Currently, target.mk passes -L "" when LLVM_STDCPP_LOCATION_$(2) is empty.

62aa899e3d Make build timestamp files robust in face of concurrent source modification.
Strategy: If the end goal is to touch e.g. `stamp.std`, then we first
touch `stamp.std.start_time` before doing anything else.  Then when
the receipe finishes, we touch `stamp.std` using the timestamp from
`stamp.std.start_time` as the reference time, and remove
`stamp.std.start_time`.

Fix .

b8e7c4fcb9 mk: Clean just one llvm build at a time. Closes
When building for multiple targets, the initial 'make' invocation
always fails. The missing build stamp causes clean-llvm to be
invoked, but clean-llvm cleans *all* llvm builds. So what happens
is that 1) all llvm's are cleaned (a no-op), 2) llvm-${target1}
builds, 3) all llvm's are cleaned (deleting llvm-${target1}),
4) llvm-${target2} is built, 5) the remaining build for ${target1}
fails because llvm does not exist.

This makes the clean operation only clean the correct llvm build.
Should greatly reduce bot failures.

acdee8b904 llvm: Add an option to statically link libstdc++
The goal of the snapshot bots is to produce binaries which can run in as many
locations as possible. Currently we build on Centos 6 for this reason, but with
LLVM's update to C++11, this reduces the number of platforms that we could
possibly run on.

This adds a --enable-llvm-static-stdcpp option to the ./configure script for
Rust which will enable building a librustc with a static dependence on
libstdc++. This normally isn't necessary, but this option can be used on the
snapshot builders in order to continue to make binaries which should be able to
run in as many locations as possible.

b3a334af6a mk: Fix llvmdeps.rs dependencies
In a multi-host build the mklldeps.py tool is getting called before
all the llvm-configs are built. I am not actually sure the cause. I
had convinced myself that DEF_LLVM_RULES needed to be called before
the llvmdeps.rs rule, but now looking at it again I can't see why.

b0a9937a6d mklldeps.py: Write to file instead of print
It seems that msys automatically converts `\n` to `\r\n` on pipe
redirection, which causes `make tidy` failure.

e91ffb0710 Link rustllvm statically, and distribute a static snapshot
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.

17a951c7bf Remove unused upcalls
The main one removed is rust_upcall_reset_stack_limit (continuation of ),
and this also removes the upcall_trace function. The was hidden behind a
`-Z trace` flag, but if you attempt to use this now you'll get a linker error
because there is no implementation of the 'upcall_trace' function. Due to this
no longer working, I decided to remove it entirely from the compiler (I'm also a
little unsure on what it did in the first place).

d3019af244 Fix double slashes in make paths.
CFG_BUILD_DIR, CFG_LLVM_SRC_DIR and CFG_SRC_DIR all have trailing
slashes, by definition, so this is correct.

c3fd430603 The purpose of these headers is to fix issues with mingw v4.0, as described in .
This works by adding this directory to GCC include search path before mingw system headers directories,
so we can intercept their inclusions and add missing definitions without having to modify files in mingw/include.
