GitHub - matthiaskrgr/icemaker: automatially find crashes in the rust compiler & tooling

Maker of ICE (Internal Compiler Error).

A small program to automatically find crashes in the rust compiler, clippy, rustdoc, rustfmt and miri. Runs executable on a vast number of rust files (such as rustcs testsuit or glacier) and filters all the crashes.

Features:

run rustc, clippy, rustdoc, rustfmt, miri, cg_clif or kani on a file and check if there is a crash
parallel execution
check different combinations of RUSTFLAGS
try to find minimal set of RUSTFLAGS that reproduces the internal compiler error
check if a file compiles stably with incremental compilation
build and run a file or tests under miri
run clippy or rustc on a file and find out if (and which) lint does not apply successfully (causes compiler errors)
find rustc diagnostics that change the file but do not managed to actually fix the broken code
use "prlimit" to protect against etenally hanging processes or OOMs during infinite loops
fuzz incremental compilation by using tree-splicer-rust to cause modifications for incremental compilation testing
automatic testcase reduction for rustc with treereduce-rust
somewhat automatic report generation for the bugtracker (for rustc atleast)

Requirements:

by default, we build with the "ci" feature disabled and require "prlimit" to limit memory and runtime of a process

History:
This project started years ago as a simple bash oneliner like

for file in `find . | grep \.rs$` ;do ; echo $file; clippy-driver $file |& grep panicked ; done

but later I decided to RIIR and add support for rustc, rustdoc, nicer output, finding UB via miri and broken lint suggestions etc...
