Types

type ABI_AMDSystemV

type ABI_AMDSystemV struct {
	// contains filtered or unexported fields
}

The calling convention of the System V AMD64 ABI is followed on Solaris, Linux, FreeBSD, macOS, and is the de facto standard among Unix and Unix-like operating systems. The first six integer or pointer arguments are passed in registers RDI, RSI, RDX, RCX, R8, R9 (R10 is used as a static chain pointer in case of nested functions[25]:21), while XMM0, XMM1, XMM2, XMM3, XMM4, XMM5, XMM6 and XMM7 are used for the first floating point arguments.
