@waruqi 怎么检测CPU是否支持sse2、avx、avx2、neon等指令集？有没有内置的函数或者推荐的解决方案？

@waruqi How to detect whether the CPU supports sse2, avx, avx2, neon and other instruction sets? Is there a built-in function or a recommended solution?

[DreamOfIce]

BTW，xmake支持ppc、longarch架构嘛？没有的话我就不写对应的rtcd支持了

BTW, does xmake support ppc and longarch architecture? If not, I will not write the corresponding rtcd support

内置 api 支持：
https://xmake.io/#/manual/project_target?id=targetadd_vectorexts

如果需要细粒度检测：
https://xmake.io/#/manual/helper_interfaces?id=detect-cc-code-snippets

Built-in api support:
https://xmake.io/#/manual/project_target?id=targetadd_vectorexts

If fine-grained detection is required:

xmake 自身支持在 ppc longarch 上跑，具体编译arch 支持，得看包对编译器的支持

xmake itself supports running on ppc longarch, and the specific support for compiling arch depends on the package's support for the compiler

add_vectorexts

能拿到结果嘛？libvpx要根据支持情况生成头文件

add_vectorexts

Can I get the result? libvpx needs to generate header files based on support

走 target:has_cflags, target:cxxflags 自己在 on_config 里判断

[waruqi]

或者走 option + configfiles + check flags https://github.com/xmake-io/xmake/blob/beafb2d5cfca0a3d52479312b6b92ca651f4959d/tests/apis/check_xxx/xmake.lua#L44

@waruqi 有办法在on_load之类的地方动态地添加option嘛？

@waruqi Is there a way to dynamically add options in places like on_load?

option 定义只能描述域定义，绑定到 target 。可以走 target:add("options", "xxx")

option definitions can only describe domain definitions, bound to target . You can go target:add("options", "xxx")

@waruqi libvpx的dll def文件没有扩展名，能不能在不改名的情况下让xmake把它当作def处理？我试了add_files("vp8/exports_enc", {rule = "platform.windows.def"})没用

@waruqi The dll def file of libvpx has no extension. Can xmake treat it as def without changing the name? I tried add_files("vp8/exports_enc", {rule = "platform.windows.def"}) to no avail

tools.xmake.install 之前你 os.cp 先 rename 下，再去 add_files 不就好了

Before tools.xmake.install, you should rename os.cp first, and then go to add_files.

额，我就是想知道能不能在不重命名的情况下实现……

Before tools.xmake.install, just rename os.cp first and then go to add_files.

Well, I just want to know if it can be achieved without renaming...

目前只能根据扩展名匹配
