    pub extended: bool,

Expand description

asm [volatile] [inline] [goto] ( template [: outputs [: inputs [: clobbers [: labels]]]] ) ; — GNU inline assembly.

The parser records what was written and nothing more: the template and the constraints are opaque strings here (adjacent string literals already concatenated), and deciding what they mean — and what of it asm! can express — is sema’s business.

Fields§

§volatile: bool

volatile or __volatile__ was written.

§inline: bool

inline or __inline__ was written.

§goto: bool

goto was written: the statement may jump to one of labels.

§template: Spanned<String>

The assembler template.

§extended: bool

Whether any colon section was written, which is what makes this extended asm: GCC treats % in a basic asm template literally, and asm("" :) as extended asm with no operands.

§outputs: Vec<AsmOperand>

The output operands, in order.

§inputs: Vec<AsmOperand>

The input operands, in order; GCC numbers them after the outputs.

§clobbers: Vec<Spanned<String>>

The clobber list: register names, "memory", "cc".

§labels: Vec<Ident>

The labels of an asm goto.
