Could not compile `core` with SIGSEGV: invalid memory reference

> or how to get more information about how exactly the SIGSEGV is happening? For this kind of problem, I've usually resorted to running `rustc` in a debugger (GDB /...

Cannot compile libcore

Package the compiler and expose on a public internet interface

Licensing is my big worry about such an endeavor. I agree that we should talk to the embedded WG about this — they may have already stocked it or want...

A Hello from the Rust embedded WG

Howdy 👋 Do you have any links or further information for what the expectations, requirements, privileges, etc. are as part of the team? For example, are there meetings we'd be...

invalid cast opcode for cast from 'i1 (i16, %"fmt::Formatter") addrspace(1)' to 'i8'

Similar issue in `core::fmt::run`: ```llvm %_19 = bitcast i8* %value.1 to i1 (%"fmt::::Opaque"*, %"fmt::Formatter"*) addrspace(1)*, !dbg !26226 ```

Assertion error in function pointer fmt::Debug implementation - LLVM ERROR: Cannot select: t2: i16 = addrspacecast[1 -> 0]

Have we yet figured out which function pointer is being printed?

Assertion error in function pointer fmt::Debug implementation - LLVM ERROR: Cannot select: t2: i16 = addrspacecast[1 -> 0]

We do have a history of adding hacks like that (especially to the formatting infrastructure) to get things working again. I'd be cool with adding it, changed to hard-code the...

Assertion error in function pointer fmt::Debug implementation - LLVM ERROR: Cannot select: t2: i16 = addrspacecast[1 -> 0]

This occurs outside of Debug formatting. For example, the implementations of async/await executors do function pointer conversions. This could be really annoying.

Assertion error in function pointer fmt::Debug implementation - LLVM ERROR: Cannot select: t2: i16 = addrspacecast[1 -> 0]

Tiny Rust example: ```rust fn alpha(i: i32) -> i32 { i + 1 } static FOO: fn(i32) -> i32 = alpha; ``` The arguments to `ConstantExpr::getBitCast`: ``` (lldb) p C->dump()...
