Go is an open source programming language that makes it easy to build simple,
reliable, and efficient software.

struct with a field named "type", x._type accesses the field.
C struct fields that cannot be expressed in Go, such as bit fields
or misaligned data, are omitted in the Go struct, replaced by
appropriate padding to reach the next field or the end of the struct.

The standard C numeric types are available under the names
C.char, C.schar (signed char), C.uchar (unsigned char),
C.short, C.ushort (unsigned short), C.int, C.uint (unsigned int),

<p>
"If" statements specify the conditional execution of two branches
according to the value of a boolean expression.  If the expression
evaluates to true, the "if" branch is executed, otherwise, if
present, the "else" branch is executed.

used to disable Branch Tracking Control Flow Integrity (BTCFI) enforcement
