在Rust 中使用内联汇编 (Inline assembly) 自Rust 1.59 以降,在 Rust 代码中内联汇编代码的语言特性已然 stable[1][2]。参考知乎上一篇文章[3],我用 Rust 的内联汇编实现了有栈协程[4]。在此过程中学到了一些知识。 本文假设读者对 x86 汇编有基础了解。 局部内联汇编与自动分配寄存器 Rust 的内联汇编一开始...
Today, the stable Rust compiler supports inline assembly on the following architectures: x86 and x86-64 ARM AArch64 RISC-V You can see more examples of inline assembly in Rust By Example, and find more detailed documentation in the reference. Destructuring assignments You can now use tuple, ...
内联汇编(inline assembly) 原始指针 原始指针(裸指针) * 和引用 &T 有类似的功能,但引用总是安全的,因为它们保证指向一个有效的数据,这得益于借用检查器(borrow checker)。解引用一个裸指针只能通过不安全代码块中来完成。 fn main() { let raw_p: *const u32 = &10; unsafe { assert!(*raw_p == ...
在Rust 中使用内联汇编 (Inline assembly) 被子飞了 既为朽木,当曝露于荒野 自Rust 1.59 以降,在 Rust 代码中内联汇编代码的语言特性已然 stable[1][2]。参考知乎上一篇文章[3],我用 Rust 的… 「Rust 语言周刊」 第 4 期· 2022-03-18 孙飞Sunface ...
另外,在编写Xous的过程中,像内联汇编(inline assembly)和工作空间(workspaces)这样的东西终于成熟了,这意味着我们需要回到过去,重新审视我们所做的一些“危险”的事情,使那些关键的几行用汇编编写的初始启动代码能够集成到我们的构建系统中。 我经常问自己“我们什么时候才能离开 Rust 发布火车(火车式发布)”,我认为的...

() to refer to a tracepoint defined in C; the macro creates an inline unsafe function on the Rust side that can be used to trigger the tracepoint. The generated function uses inline assembly to define a place for the static-key machinery to patch in a call to the C tracepoint when ...
Related to this comment. Maybe related to #93332 This feature request targets the inline assembly macro asm! and globally scope assembly global_asm! to support direct string interpolation into the assembly template. The semantic works ve...
