Bug ID: 40471
Summary: wasm: emitting object file to /dev/null fails
Product: clang
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: -New Bugs

emcc tests/hello_world.c -c -o /dev/null
(with WASM_OBJECT_FILES set by default) fails on the clang command,
===
fatal error: error in backend: section size does not fit in a uint32_t
clang-8: error: clang frontend command failed with exit code 70 (use -v to see
invocation)
clang version 9.0.0 ([email protected]:llvm-mirror/clang.git
0a4307de1174f61c465c94111f8376d3f5ed548e) ([email protected]:llvm-mirror/llvm.git
74ebd8a99755a5e0e1c14001de05fc089f0ee28f)
Target: wasm32-unknown-unknown-wasm
===
Compiling natively with clang does not throw an error if the target is
/dev/null, and changing /dev/null to something else unbreaks the wasm target.
