Struct AsmStmt 

pub struct AsmStmt {
    pub template: String,
    pub operands: Vec<AsmOperand>,
    pub clobbers: Vec<&'static str>,
    pub range: SourceRange,
}

An inline assembly statement, already in asm!’s terms.

Sema has done all the mapping (see sema/asm.rs): the template is Rust’s — %0 is {o0}, %% is %, braces are doubled — and each operand says which register and which direction. What is left for code generation is evaluating the operands and storing the outputs back.

Fields

template: String

The template in asm!’s syntax, still AT&T assembly: code generation always adds options(att_syntax).

operands: Vec<AsmOperand>

The operands, in GCC’s order (outputs, then inputs), with each tied input folded into the output it is tied to.

clobbers: Vec<&'static str>

The registers the statement clobbers, in asm!’s spelling (rax, xmm0), each of which becomes out("rax") _. "memory" and "cc" are not here: they are what asm! assumes without being told.

range: SourceRange

Where the statement was written.
