Bug ID: 27518
Summary: Fuzz failures on wasm backend
Product: libraries
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Backend: WebAssembly
Assignee: unassignedb...@nondot.org
Reporter: alonza...@gmail.com
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
The emscripten test suite has a bunch of fuzz tests, and the wasm backend fails
on several. The smallest is 3.c.
STR: in emscripten (with .emscripten set up to use latest vanilla llvm)
./emcc tests/fuzz/3.c -I tests/fuzz/include/ -w
clang tests/fuzz/3.c -I tests/fuzz/include/ -w
nodejs a.out.js
./a.out
The outputs should be identical, but are
checksum = FFFFFFFFEE4B2FFC
checksum = EE4B2FFC
This is csmith output, so running with argument '1' will print out the
intermediate hash results, which is helpful sometimes.
