如何方便去掉一些内置的编译参数

[TOMO-CAT]

你在什么场景下需要该功能？

举个例子，在 coverage 或者 debug 模式下，xmake 会自带很多编译参数，比如 nvcc 中会带上{"-G", "-g", "-lineinfo"} ， 但是出于某些特殊需求，比如我们去掉里面的 -G 参数，在根目录的xmake.lua 全局作用域中写：

if is_mode("coverage") then
  remove_cuflags("-G")
end

这样是最便捷的，但是实际上无法生效。

即使我想在 after_load 中删掉 cuflags 也无法生效，因为打印 target:get("cuflags") 时 -G 并不在其中。

Title: How to easily remove some built-in compilation parameters

In what scenario do you need this feature?

For example, in coverage or debug mode, xmake will bring many compilation parameters. For example, nvcc will bring {"-G", "-g", "-lineinfo"}, but for some special reasons Requirements, for example, we remove the -G parameter and write in the global scope of xmake.lua in the root directory:

if is_mode("coverage") then
  remove_cuflags("-G")
end

This is the most convenient, but it doesn't actually work.

Even if I want to remove cuflags in after_load it doesn't work because when target:get("cuflags") is printed, -G is not among them.

Describe possible solutions

Provide a solution to remove the built-in compilation parameters of xmake.

不写add_rules("mode.debug")，自己判断is_mode("debug")加相关flag试试？

Instead of writing add_rules("mode.debug"), try judging is_mode("debug") and adding relevant flags yourself?

那相当于整个 mode.coverage 都得自己重新写，可以试试，但感觉比较麻烦，为了去掉一个参数将内置的一些 rule 整个重写了，还有一些 rule 更复杂比如 protobuf.cpp，不太好重写

That's equivalent to having to rewrite the entire mode.coverage yourself. You can try it, but it seems troublesome. In order to remove a parameter, some built-in rules have been completely rewritten. There are also some rules that are more complicated, such as protobuf.cpp, which is not good. rewrite

set_symbols("none") 或者自定义 debug mode

好的
