Segue is an optimization technology which uses x86 segment register to store the WebAssembly linear memory base address, so as to remove most of the cost of SFI (Software-based Fault Isolation) base addition and free up a general purpose register, by this way it may: - Improve the performance of JIT/AOT - Reduce the footprint of JIT/AOT, the JIT/AOT code generated is smaller - Reduce the compilation time of JIT/AOT This PR uses the x86-64 GS segment register to apply the optimization, currently it supports linux and linux-sgx platforms on x86-64 target. By default it is disabled, developer can use the option below to enable it for wamrc and iwasm(with LLVM JIT enabled): ```bash wamrc --enable-segue=[<flags>] -o output_file wasm_file iwasm --enable-segue=[<flags>] wasm_file [args...] ``` `flags` can be: i32.load, i64.load, f32.load, f64.load, v128.load, i32.store, i64.store, f32.store, f64.store, v128.store Use comma to separate them, e.g. `--enable-segue=i32.load,i64.store`, and `--enable-segue` means all flags are added. Acknowledgement: Many thanks to Intel Labs, UC San Diego and UT Austin teams for introducing this technology and the great support and guidance!
