As discovered in #9925, it turns out that we weren't using jemalloc on most
platforms. Additionally, on some platforms we were using it incorrectly and
mismatching the libc version of malloc with the jemalloc version of malloc.
Additionally, it's not clear that using jemalloc is indeed a large performance
win in particular situtations. This could be due to building jemalloc
incorrectly, or possibly due to using jemalloc incorrectly, but it is unclear at
this time.
Until jemalloc can be confirmed to integrate correctly on all platforms and has
verifiable large performance wins on platforms as well, it shouldn't be part of
the default build process. It should still be available for use via the
LD_PRELOAD trick on various architectures, but using it as the default allocator
for everything would require guaranteeing that it works in all situtations,
which it currently doesn't.
Closes#9925
Sadly, there's a lack of resources for maintaining the `rust` tool,
and we decided in the 2013-10-08 Rust team meeting that it's better
to remove it altogether than to leave it in a broken state.
This deletion is without prejudice. If a person or people appear who
would like to maintain the tool, we will probably be happy to
resurrect it!
Closes#9775
This lets the C++ code in the rt handle the (slightly) tricky parts of
random number generation: e.g. error detection/handling, and using the
values of the `#define`d options to the various functions.
This will make sure that system files that rust binaries depend on in Windows get packaged into stage0 snapshots as well as into Windows installer.
Currently these include `libgcc_s_dw2-1.dll`, `libstdc++-6.dll` and `libpthread-2.dll`. Note that the latter will need to be changed to `pthreadGC2.dll` once Windows build bots get upgraded to mingw 4.0

This change adds --soft-float option for generating
software floating point library calls.
It also implies using soft float ABI, that is the same as llc.
It is useful for targets that have no FPU.
This modifies the command-line usage of rustdoc to intake its own JSON output as
well as a rust source file. This also alters the command line from
`rustdoc input file` to `rustdoc file` with the input/output formats specified
as -r and -w, respectively.
When using a JSON input, no passes or plugins are re-run over the json, instead
the output is generated directly from the JSON that was provided. Passes and
plugins are still run on rust source input, however.
This change adds -Z soft-float option for generating
software floating point library calls.
It also implies using soft float ABI, that is the same as llc.
It is useful for targets that have no FPU.
They're getting smaller each time though!
The highlight of this round is source files in documentation. Still trying to figure out the best syntax-highlighting solution.
This purges doc/{std,extra} entirely during a `make clean` instead of just the
html files in some top level directories. This should help old documentation
from showing up on static.rust-lang.org

Three things in this commit:
1. Actually build the rustpkg tutorial. I didn't know I needed this when
I first wrote it.
2. Link to it rather than the manual from the
tutorial.
3. Update the headers: most of them were one level too deeply
nested.
Removes old rustdoc, moves rustdoc_ng into its place instead (plus drops the _ng
suffix). Also shreds all reference to rustdoc_ng from the Makefile rules.
This large commit implements and `html` output option for rustdoc_ng. The
executable has been altered to be invoked as "rustdoc_ng html <crate>" and
it will dump everything into the local "doc" directory. JSON can still be
generated by changing 'html' to 'json'.
This also fixes a number of bugs in rustdoc_ng relating to comment stripping,
along with some other various issues that I found along the way.
The `make doc` command has been altered to generate the new documentation into
the `doc/ng/$(CRATE)` directories.
Many people will be very confused that their debug! statements aren't working
when they first use rust only to learn that they should have been building with
`--cfg debug` the entire time. This inverts the meaning of the flag to instead
of enabling debug statements, now it disables debug statements.
This way the default behavior is a bit more reasonable, and requires less
end-user configuration. Furthermore, this turns on debug by default when
building the rustc compiler.
Some of the functions could be converted to rust, but the functions dealing with
signals were moved to rust_builtin.cpp instead (no reason to keep the original
file around for one function).

Because less C++ is better C++!

This patch fixes some errors of MIPS target, however, MIPS C ABI is still broken. I will send another PR to fix the problem.
Because MIPS target has no "generic" CPU name, I add --target-cpu and --target-feature to RUST_FLAGS. In order to workaround the "compact frame descriptions incompatible with DWARF2 .eh_frame" problem, the linker I used is CXX but not CC.
Now rustdoc_ng will be built as both a binary and a library (using the same
rules as all the other binaries that rust has). Furthermore, this will also
start building rustdoc_ng unit tests (and running them).
Note that some `rustdoc_ng` tests were removed, but @cmr says they weren't supposed to be there in the first place. The rustdoc_ng code should also be included in `make install` and `make dist` now.
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.

This is a reopening of the libuv-upgrade part of #8645. Hopefully this won't
cause random segfaults all over the place. The windows regression in testing
should also be fixed (it shouldn't build the whole compiler twice).
A notable difference from before is that gyp is now a git submodule instead of
always git-cloned at make time. This allows bundling for releases more easily.
Closes#8850
The new glob tests created tmp/glob-tests as a directory, but the never removed
it. The `make clean` target then attempted to `rm -f` on this, but it couldn't
remove the directory. This both changes the clean target to `rm -rf` tmp files,
and also alters the tests to delete the directory that all the files are added
into.
This should make benchmarks easier to understand. But, it doesn't work.
BENCH_RS in mk/tests.mk has everything, from what I can tell in remake, but
only those that are direct children of src/test/bench get build and run.
@graydon, can you lend your expertise? I can't make heads or tails of this
makefile.
It turns out that gyp (libuv's new build system) wants x64 for a 64-bit x86
architecture and ia32 for a 32-bit architecture, so this performs the relevant
mapping and then invokes libuv's configure script with the appropriate target
architecture.
This can be verified by running make with VERBOSE=1 and seeing that beforehand
on a 64-bit build libuv was passed "-arch i386" and now it's passed
"-arch x86_64"
Closes#8826
The syntax of the script requires python < 3, and so does our build system so we
can just use CFG_PYTHON to run the script. This prevents build failures where
`python` is actually python3 or later.
There were two main differences with the old libuv and the master version:
1. The uv_last_error function is now gone. The error code returned by each
function is the "last error" so now a UvError is just a wrapper around a
c_int.
2. The repo no longer includes a makefile, and the build system has change.
According to the build directions on joyent/libuv, this now downloads a `gyp`
program into the `libuv/build` directory and builds using that. This
shouldn't add any dependences on autotools or anything like that.

This makes it relatively easy for us to split testsuite load between machines in buildbot. I've added buildbot-side support for setting up builders with -a.b suffixes (eg. linux-64-opt-vg-0.5, linux-64-opt-vg-1.5, linux-64-opt-vg-2.5, linux-64-opt-vg-3.5, linux-64-opt-vg-4.5 causes the valgrind-supervised testsuite to split 5 ways across hosts).
We currently have no need for the frame pointers on any platform. They
may eventually be needed on platforms without an equivalent to the DWARF
call frame information to walk the stack in the garbage collector.
Closes#7477
`stdtest` and `extratest` expects to be able to write to `tmp` directory under the current working directory, so the first commit creates `tmp` directory and changes the directory before running tests.
The second commit adds `--bench` argument to test runs and copies metrics from the remote device.
