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

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.

This is actually super helpful. Thanks for the tip!

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

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.
