"codecbench of meshoptimizer" sample introduction
|
|
==============
|
|
|
|
This sample demonstrates how to build [codecbench of messoptimizer](https://github.com/zeux/meshoptimizer) into
|
|
WebAssembly with simd support and run it with iwasm.
|
|
|
|
## Preparation
|
|
|
|
please refer to [installation instructions](../README.md).
|
|
|
|
## Build with wasi-sdk
|
|
|
|
``` shell
|
|
$ 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.
|
|
|
|
``` shell
|
|
$ 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 \
|
|
-o codecbench.wasm
|
|
$ ls -l codecbench.wasm
|
|
```
|
|
|
|
## Run workload
|
|
|
|
Firstly please build iwasm with simd support:
|
|
|
|
``` shell
|
|
$ cd <wamr dir>/product-mini/platforms/linux/
|
|
$ mkdir build && cd build
|
|
$ cmake ..
|
|
$ make
|
|
```
|
|
|
|
Then compile wasm file to aot file and run:
|
|
|
|
``` shell
|
|
$ <wamr dir>/wamr-compiler/build/wamrc -o codecbench.aot codecbench.wasm
|
|
$ <wamr dir>/product-mini/platforms/linux/build/iwasm codecbench.aot
|
|
```
