You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: entries.go
    path of file: ./repos/parca-agent/internal/dwarf/frame
    
    the code of the file until where you have to start completion: // nolint:stylecheck,deadcode,varcheck
package frame

import (
	"debug/elf"
	"encoding/binary"
	"fmt"
	"sort"
)

// CommonInformationEntry represents a Common Information Entry
    
func (ptrEnc ptrEnc) Supported() bool {
	if ptrEnc != ptrEncOmit {
		szenc := ptrEnc & 0x0f
		if ((szenc > ptrEncUdata8) && (szenc < ptrEncSigned)) || (szenc > ptrEncSdata8) {
			// These values aren't defined at the moment
			return false
		}
		if (ptrEnc&ptrEncFlagsMask)&^ptrEncSupportedFlags != 0 {
			// Currently only the PC relative flag is supported
			return false
		}
	}
	return true
}
