Thanks for the report! Looks like LLD changed when upgrading to LLVM 10. Some work needs to happen to update to the new output of LLD, and that'll take some time for me to implement unfortunately. |

This commit updates the threads transformation for LLVM 10 where LLD has has breaking changes from LLVM 9. While previously the support here attempted to straddle multiple LLVM styles this is now removed in favor of simply supporting LLVM 10's style of output. This means that wasm-bindgen will only be compatible with recent nightlies and forward. The major change here is that the `__wasm_init_memory` function is automatically called by the `start` function. We handle that by placing the previous `start` function first, before stack/tls allocation. Other changes are to delete all the old code from pre-llvm-9. Closes rustwasm#2175

Describe the Bug
The example raytrace-parallel does not compile.
Steps to Reproduce
git clone https://github.com/rustwasm/wasm-bindgen.gitcd wasm-bindgen/examples/raytrace-parallelsh build.shnote: rust-lld: error: unknown argument: --passive-segmentsExpected Behavior
The code should compile. I played with this example last Sunday, and the code was compiling and running correctly.
Actual Behavior
The code currently does not compile with rust nightly (May 31th).
Additional Context
Note that, removing
RUSTFLAGS='-C target-feature=+atomics,+bulk-memory'fix the compilation problem. However, this provokes a runtime error (due to missing feature), which, I think, is expected.The text was updated successfully, but these errors were encountered:
