[Pkg-rust-maintainers] Bug#921058: Cannot release-build crate `sysinfo` on i386
Wolfgang Silbermayr

Fri Feb 1 06:58:17 GMT 2019
Package: rustc
Version: 1.32.0+dfsg1-1
Severity: normal
When using the debian package of rustc, an attempt to build the sysinfo 0.8.0
crate fails:
> LLVM ERROR: No support for lowering a copy into EFLAGS when used by this
> instruction!
I only got this on the i386 with the debian package of rustc, in both version
1.31.0 and 1.32.0. A rustc installed through rustup works fine. The debian
rustc only shows this behavior when compiling a release build of the crate, the
debug build works just fine.
It seems to be the cause for the process-viewer build failure on i386 [0].
LLVM weekly #240 [1] mentions a fix for a subtle bug in EFLAGS copy lowering
[2], but as far as I can see, the debian llvm 0.7 code has these changes
included already, so I assume this is not the cause.
The cause might be triggered by the way structures are defined and/or used in
the sysinfo crate's src/linux/processor.rs file. Even though I didn't directly
find something suspicious in the source code, for example replacing the
contents of the CpuValues::work_time(&self) function with an unimplemented!()
call makes the crate compile, I assume because the relevant code gets optimized
out.
