The following compiles with rustc since 1.14.0 but not mrustc:
mod m {
use *;
}
fn main() {}
Parse: V V V
star.rs:2: Unexpected(TOK_STAR)
terminate called after throwing an instance of 'ParseError::Unexpected'
what(): std::exception
We use this in Syn within some generated code, so it becomes necessary for building serde_derive.
syn/codegen/src/main.rs#L1015
.
rustc-1.19.0-src/src/vendor/log/src/lib.rs
contains:
#[repr(usize)]
#[derive(Copy, Eq, Debug)]
pub enum LogLevelFilter {
mrustc seems to define usize
as uintptr_t
, but mrustc converts this to:
struct e__ZN10log$$0_3_714LogLevelFilter {
unsigned int TAG;
};
usize
is correctly converted to uintptr_t
later on, in ::"log-0_3_7"::max_log_level
, resulting in a memcpy
of 64 bits (uintptr_t
size on 64-bit platforms) to a data structure that is only unsigned int
(32-bit).
Disclaimer: I don't know Rust, so double-check my assumptions.
Fails on the following step:

I've successfully bootstrapped rust/cargo 1.20 and 1.21 using your compiler.
I'm extremely pleased, as this allows rust to be used in restrictive corporate environments.
Thank you very much for your work.
In order to integrate the bootstrap step, it would be nice, if this very usable state had a version number, so I don't have to resign to using a commit hash (which makes managers somehow uneasy).
Maybe you could even spare a version tag every other month? :-)

(I’ve added musl targets to src/main.cpp
, src/trans/target.cpp
and minicargo and applied our patches for musl to rustc-1.19.0. It works on x86_64 musl.)
Environment:
This is the approach Cargo takes to best support using an old Cargo to compile new crates that use Cargo.toml manifest keys introduced in a later version of Cargo.
I have hit this in two unrecognized keys so far.
EXCEPTION: Unknown key `publish` in [package]
TODO: Unknown manifest section example
Aborted (core dumped)
In both cases it would have worked to just ignore the key and keep going.
This is minimized from Syn 0.12 which uses the Token!
type macro heavily internally.
macro_rules! Ty {
() => { u8 }
}
fn f() -> Option<Ty![]> {
None
}

I guess it's due some parsing issues of the Cargo.toml.
About RUSTSRC in Makefile (https://github.com/thepowersgang/mrustc/blob/master/Makefile#L168):
This will not work in most sane build environments. Most operating systems will have to fetch rustc-nightly in advance due to isolated build-environments. I suggest to remove the rule and check for a local file, or anything similar (better yet, but I'm not a rust dev: try to implement tests without dependency on rustc-nightly). For example for GNU Guix I will fetch the rustc-nightly tarball as a separate file before the build starts.
I'm really looking forward where this project is going, with the bootstrapping issue of rustc (rustc requiring rustc for build).
As far as I understand mrustc, just taking a first short look at the code, it only requires the rustc-nightly source for tests, correct?
Seen both with GCC v5.5.0 and v5.4.0 (Linux Mint 18), x86-64
GCC's code generation for a particular function in librustc leads to uninitialised data being or-ed into the tag of an Option which is then matched upon and will abort due to the tag being neither 0 or 1.

Same error in Travis. It looks like this was introduced in c7e7652.
I was doing make output/rustc -j 8
to compile rustc. Then I saw that when building LLVM, only one core was utilized, even though I have 7 more.
I tried build mrustc on cygwin. There was an error:
src/main.cpp:744:52: error: no matching function for call to 'std::basic_string::basic_string(const char*&, char*&)'
auto name = ::std::string(desc, pos);
..............................
src/main.cpp:744:52: error: invalid conversion from 'char*' to 'char' [-fpermissive]
auto name = ::std::string(desc, pos);
I was able to fix it by changing src / main.cpp: 744: "pos" -> "* pos".
Would it be possible to use mrustc to compile Rust for TI m68k calculators (TI-89, TI-92+, TI-Voyage 200) by combining mrustc with TIGCC (which was forked from gcc v4.1.2 and supports GCC extensions)?
On my PC (Fedora 27) make RUSTCSRC
fails without it.
If code such as the following (used by bindgen) is written:
#[repr(C)]
#[derive(Copy, Clone, Debug, Default, Eq, Hash, Ord, PartialEq, PartialOrd)]
pub struct __BindgenBitfieldUnit<Storage, Align>
where
Storage: AsRef<[u8]> + AsMut<[u8]>,
{
storage: Storage,
align: [Align; 0],
}
Mrustc fails with the error Failed to find an impl of ::"core"::clone::Clone for [Align/*I:1*/; 0]
. This fine in the official compiler, which inserts Clone
bounds for type parameters where needed, which I assume is what is missing in mrustc.
EDIT: Actually this is not as simple as I thought, and the example above doesn't trigger the behaviour described, I'll update this issue if I can get a proper MWE.
EDIT2: Actually it does trigger the behaviour, I was just having some caching issues when testing it.
Hi! Perhaps borrow checking could be implemented in future with use of polonius, a library that models the borrow checker, if this is in scope/relevant. I thought that a reason that borrow checking isn't implemented in mrustc is the amount of work required to do it, but perhaps this library could assist with that?
sed -r
doesn't work, and for some reason FMT
doesn't work either.
Why re-write stuff ?

(Using mrustc compiled with llvm 3.9.1 and gcc 5.5.0)
Note: This is part of a larger effort to bootstrap Mozilla's rust implementation using mrustc. Are we setting this up correctly? (should we use mrustc 0.8.0 to build rustc 1.19.0 or rather rustc 1.20.0?)
Host system: GuixSD 0.15.0.
gcc: 5.5.0
I wonder, is this project already capable of bootstrapping rustc on platforms for which there's no binary snapshot?
My use case is to build Rust on x86_64 with musl libc.
src/parse/tokentree.hpp
, and src/parse/ttstream.hpp
, for example.
This issue collects the alignment of struct members on gcc.
The following program has been run:
#define _GNU_SOURCE
#include <stdio.h>
#include <stdint.h>
#include <stddef.h>
struct foo {
unsigned char a;
uint16_t b;
};
int main() {
struct foo f;
printf("b_offset = %zu\n", offsetof(struct foo, b));
printf("b_size = %zu\n", sizeof(f.b));
return 0;
}
On armhf, this results in: b_offset = 2, b_size = 2.
Then I modified it accordingly to get:

Thank you for your help
in src/main.cpp, line 728:
auto* pos = ::std::strchr(desc, '=');
a few lines later:
auto name = ::std::string(desc, pos);
compiler throws an error:
src/main.cpp:728:52: error: Invalid conversion from 'char*' to 'std::basic_string<char>::size_type {aka long unsigned int}'
Changing pos to *pos makes it compile here, but not sure if that is the correct solution.
Can't patch rustcsrc when execute "make RUSTCSRC".
I'm interested in using mrustc to allow me to write code in Rust for a platform not supported by LLVM (ESP8266), then transpile it to C and call it from a shim written in C/C++. I tried using mrustc on a trivial library and discovered that, even with #[no_mangle], the resulting C function did not retain its original Rust name.
Other features that would be helpful for this include an option to produce C output without compiling it and an option to use regular rustc to produce MIR and then transpile that to C.
I haven't tried using mrustc on Rust code that calls out to a C or C++ library, but if that's not supported already, it would be critical to my use case (e.g. writing Rust code on top of the ESP8266 Arduino library).
Thanks for your work on this project so far!
I managed to build mrustc and minicargo, but I'm getting errors trying to use it to compile a trivial example. build_rustc_with_minicargo.sh completed successfully so mrustc must be functional. I tried adding the minicargo flags used in build_rustc_with_minicargo.sh, but that didn't help either.

In several places, such as make test
, there are references to like -L output/libs
, but that folder definitely doesn't exist on my machine after building mrustc
. In make test
, it also has -L output
, and output
has lots of libraries in it, so that makes sense. I feel like -L output/libs
might be an obsolete flag?
It would be nice if the README documented how to compile code using mrustc
. After observing how the Makefile is able to use mrustc
, I figured it out, and it's bascially just
mrustc hello.rs -L output
once all the paths are adjusted as appropriate.
I have not been able to figure out minicargo
... it seems to just do nothing, and the output is always either completely empty, Usage: minicargo <package dir>
, or EXCEPTION: Unable to open file 'Cargo.toml'
. I haven't been able to get it to do anything else.
My current work on esp-rs requires using the generated C code as a library from a C++ shim. Any chance of mrustc generating headers? makeheaders was unable to do it adequately.
In trying to build a simple ESP8266 firmware example, I am unable to compile my crate of generated bindings to the Arduino library because it depends on deriving Copy on unions:
:0: BUG:src/expand/derive.cpp:2186: TODO: handle - Handle #[derive] for other item types - Union
This is very similar to #55, still trying to get the libc crate to compile. The following is minimized from their use of cfg_if!
and compiles with rustc 1.19.0 but not mrustc.
macro_rules! outer {
({ $($x:item)* }) => {}
}
outer! {
{inner!{}}
}
libc/src/lib.rs:5: error:0:Expected token in match arm
I'd love to at least attempt to add support for the Xtensa used in the ESP8266/32 WiFi chips, as it will probably be a long time until LLVM gains support for it. What would be involved in adding another target? It looks like most of the changes would involve additions to src/trans/target.cpp, but are there any gotchas to watch out for?
