Using constructs with operands requires some additional syntax.
asm()
The construct syntax is described in:
• "Assembly Construct Template" on page 1-64
• "Assembly Construct Operand Description" on page 1-68
• "Assembly Constructs with Multiple Instructions" on page 1-74
• "Assembly Construct Reordering and Optimization" on page 1-74

Assembly Construct Template

Using constructs, you can specify the operands of the assembly
asm()
instruction using C expressions. You do not need to know which registers
or memory locations contain C variables.

ASM() Construct Syntax:

Use the following general syntax for your
asm(
template
[:[constraint(output operand)[,constraint(output operand)...]]
[:[constraint(input operand)[,constraint(input operand)...]]
[:clobber]]]
);
The syntax elements are defined as:
