This is the 2nd patch set for gccrs, since v1 we have dropped the changes
for target hooks which are not nessecary for us right now. This now
focuses directly on the front-end the only patch that affects GCC now is a
tweak to debug info. Note we are close to merging our port of the C++
constexpr code into our front-end but this patch set does not include this
yet.
Thanks to Open Source Security, inc and Embecosm for sponsoring this work.
Special thanks to all of those who have contributed thus far.
See our branch over on https://gcc.gnu.org/git/?p=gcc.git;a=shortlog;h=refs/heads/devel/rust/master
We are currently testing on every commit the following systems:
- Debian i386 - all tests passing
- Debian testing-x86_64 - all tests passing
- Fedora arm64 - all tests passing
- Fedora X86_64 - all tests passing
- OpenSUSE Leap X86_64 - all tests passing
- OpenSUSE tw X86_64 - all tests passing
- Rawhide X86_64 - all tests passing
- macos x86_64 - all tests passing
- Debian ppc64 - some tests failing
- Fedora ppc64le - some tests failing
- Fedora s390x - some tests failing

The Rust 'char' type should use the DWARF DW_ATE_UTF encoding.

From: Philip Herron <philip.herron@embecosm.com>
This testsuite is heavily inspired from the lto testsuite which uses a
pattern that each file is compiled to an object file and finally linked
together. Since rust does not have headers/prototypes we rely on the
ordering here so that all files numbered greater than zero get compiled to
object files first leaving the _0 file free to test the 'extern crate' and
use keywords to force testing of the compiler to read metadata from the
other 'crates'.

This suite of tests has two sections compile/*.rs and compile/torture/*.rs.
The first section are all dg-compile tests which contain dg-warning or
dg-error annotations and some with no annotations to ensure they do create
a resulting asm output. The second section is the same but have tests which
are ran with the full torture options, as during development the test case
may have had an issue with a specific optimization level.

From: Philip Herron <philip.herron@embecosm.com>
This is similar to the compile/torture/*.rs test cases but all of these are
dg-execute testcases so they get compiled, linked and executed by default,
all the while being compiled with the matrix of torture options.
The only caveat here is that currently gccrs does not currently support
the main shim yet so we have a C-style main function here returning zero
which is not supported in Rustc.

This is a full C++11 class hierarchy representing the Rust AST. We do not
allow dynamic_cast and so the main mechanism to work with the AST is by
using the visitor interface. Slowly we are adding TREE_CODE style node
types to the AST which will allow for more ways to work with the AST but
for now this is it.
