// FuncProps describes a set of function or method properties that may

Examples:

	MOVD $2, R0
	PCALIGN $32
	MOVD $4, R1
	PCALIGN $128
	MOVD $8, R2
	RET

On arm64, functions in Go are aligned to 16 bytes by default, we can also use PCALIGN to set the
function alignment. The functions that need to be aligned are preferably using NOFRAME and NOSPLIT
to avoid the impact of the prologues inserted by the assembler, so that the function address will

Cover is a program for analyzing the coverage profiles generated by
'go test -coverprofile=cover.out'.

Cover is also used by 'go test -cover' to rewrite the source code with
annotations to track which parts of each function are executed (this
is referred to "instrumentation"). Cover can operate in "legacy mode"
on a single Go source file at a time, or when invoked by the Go tool
it will process all the source files in a single package at a time
