请求llvm-releases

你在什么场景下需要该功能？

windows下使用libcxx时，拉取预编译二进制会很方便，xrepo中自带的llvm-mingw使用时需要切换到mingw平台，不能使用msstl，该预编译包含libcxx的同时可以使用msstl。

描述可能的解决方案

该包为预编译包，集成较为简单：

In what scenario do you need this feature?

When using libcxx under Windows, it is very convenient to pull the precompiled binary. When using the llvm-mingw that comes with xrepo, you need to switch to the mingw platform and cannot use msstl. The precompiled version includes libcxx and you can use msstl at the same time.

Describe possible solutions

This package is a precompiled package, and integration is relatively simple:

这工具链不 "标准"，用 set_toolchains("clang@trcrsired-llvm-mingw") 也识别不了（找不到 clang++），可能需要 custom toolchain 才能用。。

package("trcrsired-llvm-mingw")
    set_kind("toolchain")
    set_homepage("https://github.com/trcrsired/llvm-releases")
    set_license("Apache-2.0")

    local version_map = {
        ["20.0.0"] = "2024.11.24"
    }

    add_urls("https://github.com/trcrsired/llvm-releases/releases/download/llvm$(version)/x86_64-windows-gnu.tar.xz", {version = function (version)
        local llvm_ver = tostring(version)
        local ver = version_map[llvm_ver]
        return string.format("%s-%s", version:major(), ver:gsub("%.", ""))
    end})

    add_versions("20.0.0", "98504a1ecb62f835918eda365f221d194765621219903c9f277ea64fff887db9")

    on_install("@windows|x64", function (package)
        for _, dir in ipairs(os.dirs("*")) do
            os.vcp(path.join(dir, "/*"), package:installdir())
        end
    end)

    on_test(function (package)
        os.vrun("llvm-config --version")
    end)
