An asm declaration has the form

[asm-declaration:](#nt:asm-declaration "9.11 The asm declaration [dcl.asm]")  
[*attribute-specifier-seq*](dcl.attr.grammar#nt:attribute-specifier-seq "9.13.1 Attribute syntax and semantics [dcl.attr.grammar]")opt asm ( [*balanced-token-seq*](dcl.attr.grammar#nt:balanced-token-seq "9.13.1 Attribute syntax and semantics [dcl.attr.grammar]") ) ;

The asm declaration is conditionally-supported;
any restrictions on the [*balanced-token-seq*](dcl.attr.grammar#nt:balanced-token-seq "9.13.1 Attribute syntax and semantics [dcl.attr.grammar]") and
its meaning are implementation-defined[.](#1.sentence-2)

The optional [*attribute-specifier-seq*](dcl.attr.grammar#nt:attribute-specifier-seq "9.13.1 Attribute syntax and semantics [dcl.attr.grammar]") in
an [*asm-declaration*](#nt:asm-declaration "9.11 The asm declaration [dcl.asm]") appertains to the asm declaration[.](#1.sentence-3)

[*Note [1](#note-1)*:

Typically it is used to pass information through the implementation to
an assembler[.](#1.sentence-4)
