LLVM ERROR: Not supported instr #124

sobolevn · 2021-01-08T18:56:40Z

I am using this example: https://github.com/Rahix/avr-hal/tree/d17a441a667dd65e5a9be75b0e71d1beadf93e84/boards/arduino-uno

I have also executed rustup component add rust-src

And it fails to compile with this error:

Regression in nightly-2021-01-08, rust version 1.51.0-nightly (c8915eebe 2021-01-07), should probably file a compiler-builtins bug. Diff, probably because the last 4 months of changes in compiler-builtins were used.

Rahix · 2021-01-25T14:09:57Z

We have identified the problem, let's see how it will be solved. In the meantime, for anyone stumbling upon this issue: Just use an older toolchain like nightly-2021-01-07 for now. With rustup, installing and using it will be as easy as:

rustup toolchain install nightly-2021-01-07
# ...
cargo +nightly-2021-01-07 build

Urhengulas · 2021-01-25T15:47:49Z

Thank you for the workaround!
Is there a way to support you in fixing it?

Due to a compiler regression [1], latest nightly builds of the compiler are currently broken. Instead, suggest using the last working build which was `nightly-2021-01-07`. This commit can hopefully be reverted once the compiler is fixed again. [1]: rust-lang/compiler-builtins#400 Ref: #124

Newer nightly fails to compile: LLVM ERROR: Not supported instr: <MCInst 258 <MCOperand Reg:1> <MCOperand Imm:15> <MCOperand Reg:45>> error: could not compile `compiler_builtins` Already reported upstream: Rahix/avr-hal#124 (comment)

ewpratten · 2021-03-01T20:01:17Z

For anyone that needs this information:

Rust nightly-2020-11-20 is the last version that was built that both doesn't have this issue, and had a successful rls build.

So, if you are (for example) looking for a release where you can work with avr-hal and have VSCode give you useful autocomplete and highlighting, 2020-11-20 is the version to use.

Sources: toolsuite build info and rustdatehash

sobolevn · 2021-03-01T20:35:02Z

One more solution to rls problem (2021-01-07 does not have rls component): rls can be replaced with https://github.com/rust-analyzer/rust-analyzer

mike-kfed · 2021-03-10T15:15:02Z

I found it's easiest to create a file called rust-toolchain in your projects directory with following content

[toolchain]
channel = "nightly-2021-01-07"
components = ["rust-src"]

afterwards you can simply run cargo build and all is fine :)

ewpratten · 2021-03-10T15:18:52Z

For my own future reference: these are the docs for rust-toolchain files.

gcc backend will be soon supported for rust
so can we use them instead?

Pardon my way too whity response.

Hi everyone. Same problem here, I just cargo generate --git https://github.com/Rahix/avr-hal-template.git and then cargo build.

I've tried rustup toolchain install nightly-2021-01-07 and in my rust-toonchail.toml:

[toolchain]
channel = "nightly-2021-01-07"
components = [ "rust-src" ]

and then cargo build I got:

and with cargo +nightly-2021-01-07 build I got:

        rustup component add rust-src

but I make rustup component add rust-src and I obtain the same output.

Thank you for your help and time.

lights0123 · 2021-08-05T17:18:14Z

@ssmgcode you need to add the rust-src component for the particular toolchain. I believe you can use the same +«toolchain-version» trick you can use with other Rust commands.

Rahix · 2021-08-05T18:41:20Z

@ssmgcode, it seems your rustup is not picking up rust-toolchain.toml? What version of rustup do you have? Maybe you need to do a rustup self update?

ssmgcode · 2021-08-06T06:14:45Z

@ssmgcode you need to add the rust-src component for the particular toolchain. I believe you can use the same +«toolchain-version» trick you can use with other Rust commands.

Thank you! I made rustup +nightly-2021-01-07 component add rust-src, deleted the project folder and create it again from template. Then I just cargo build and it worked nicely!

ssmgcode · 2021-08-06T06:40:49Z

@ssmgcode, it seems your rustup is not picking up rust-toolchain.toml? What version of rustup do you have? Maybe you need to do a rustup self update?

Yes, it seemed, it was a really weird thing. My rustup version is rustup 1.24.3 (ce5817a94 2021-05-31), I think it's a recent version because I started using Rust and installed it a month ago, sort of.

Thank you for your time guys, this makes me happy.
