Wenyong Huang 365ec6360b Update build scripts and documents of workload samples for wasi-sdk-12.0 (#484 ) Update the build scripts of sample workloads (meshoptimizer/bwa/wasm-av1) to use the wasi-sdk-12.0 firstly to build the workload and discard clang-11, as wasi-sdk-12 supports wasi, simd and pthread better. And update the related documents. Also modify wasm mini loader to sync up with the change of wasm normal loader. Signed-off-by: Wenyong Huang <wenyong.huang@intel.com>		2020-12-29 14:41:09 +08:00

"codecbench of meshoptimizer" sample introduction

This sample demonstrates how to build codecbench of messoptimizer into WebAssembly with simd support and run it with iwasm.

Preparation

please refer to installation instructions.

Build with wasi-sdk

$ mkdir build && cd build
$ cmake ..
$ make
# to verify
$ ls codecbench.wasm

Or build with EMSDK

EMSDK is another toolchain to compile C/C++ code to WASM. In this case, the output wasm file might have a higher performance than the file generated by wasi-sdk.

$ git clone https://github.com/zeux/meshoptimizer.git
$ cd messoptimizer
$ em++ tools/codecbench.cpp src/vertexcodec.cpp src/vertexfilter.cpp \
       src/overdrawanalyzer.cpp src/indexgenerator.cpp src/vcacheoptimizer.cpp \
       src/clusterizer.cpp src/indexcodec.cpp src/vfetchanalyzer.cpp \
       src/spatialorder.cpp src/allocator.cpp src/vcacheanalyzer.cpp \
       src/vfetchoptimizer.cpp src/overdrawoptimizer.cpp src/simplifier.cpp \
       src/stripifier.cpp -O3 -msimd128 \
       -s TOTAL_MEMORY=268435456 -s "EXPORTED_FUNCTIONS=['_main']" \
       -o codecbench.wasm
$ ls -l codecbench.wasm

Run workload

Firstly please build iwasm with simd support:

$ cd <wamr dir>/product-mini/platforms/linux/
$ mkdir build && cd build
$ cmake .. -DWAMR_BUILD_SIMD=1
$ make

Then compile wasm file to aot file and run:

$ <wamr dir>/wamr-compiler/build/wamrc --enable-simd -o codecbench.aot codecbench.wasm
$ <wamr dir>/product-mini/platforms/linux/build/iwasm codecbench.aot
