"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 clang-11 and wasi-sdk
|
||
|
|
|
||
|
|
``` shell
|
||
|
|
$ mkdir build && cd build
|
||
|
|
$ cmake ..
|
||
|
|
$ make
|
||
|
|
# to verify
|
||
|
|
$ ls codecbench.wasm
|
||
|
|
```
|
||
|
|
|
||
|
|
## Or build with EMCC
|
||
|
|
|
||
|
|
EMCC is another toolchain to compile C code to WASM. In this case, will have
|
||
|
|
a higher performance with EMCC.
|
||
|
|
|
||
|
|
``` shell
|
||
|
|
$ git clone https://github.com/zeux/meshoptimizer.git
|
||
|
|
$ cd messoptimizer
|
||
|
|
$ emcc 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:
|
||
|
|
|
||
|
|
``` shell
|
||
|
|
$ 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:
|
||
|
|
|
||
|
|
``` shell
|
||
|
|
$ cd <wamr dir>/wamr-compiler/build
|
||
|
|
$ ./wamrc --enable-simd -o codecbench.aot codecbench.wasm
|
||
|
|
$ cd <wamr dir>/product-mini/platforms/linux/
|
||
|
|
$ ./iwasm codecbench.aot
|
||
|
|
```
|
||
|
