configure.ac: setup build tools and register objects main.c: wrap main with rb_wasm_rt_start to handle asyncify unwinds tool/m4/ruby_wasm_tools.m4: setup default command based on WASI_SDK_PATH environment variable. checks wasm-opt which is used for asyncify. tool/wasm-clangw wasm/wasm-opt: a clang wrapper which replaces real wasm-opt with do-nothing wasm-opt to avoid misoptimization before asyncify. asyncify is performed at POSTLINK, but clang linker driver tries to run optimization by wasm-opt unconditionally. inlining pass at wasm level breaks asyncify's assumption, so should not optimize before POSTLIK. wasm/GNUmakefile.in: wasm specific rules to compile objects

# A Clang wrapper script to fake the clang linker driver.
|
|
# Clang linker automatically uses wasm-opt with -O if it found.
|
|
# However optimization before asyncify causes misoptimization,
|
|
# so wrap clang to insert our fake wasm-opt, which does nothing, in PATH.
