示例1: FindNonConstCalls
// FindNonConstCalls returns the set of callsites of the given set of methods
// for which the "query" parameter is not a compile-time constant.
func FindNonConstCalls(cg *callgraph.Graph, qms []*QueryMethod) []ssa.CallInstruction {
cg.DeleteSyntheticNodes()
// package database/sql has a couple helper functions which are thin
// wrappers around other sensitive functions. Instead of handling the
// general case by tracing down callsites of wrapper functions
// recursively, let's just whitelist the functions we're already
// tracking, since it happens to be good enough for our use case.
okFuncs := make(map[*ssa.Function]struct{}, len(qms))
for _, m := range qms {
okFuncs[m.SSA] = struct{}{}
}
bad := make([]ssa.CallInstruction, 0)
for _, m := range qms {
node := cg.CreateNode(m.SSA)
for _, edge := range node.In {
if _, ok := okFuncs[edge.Site.Parent()]; ok {
continue
}
cc := edge.Site.Common()
args := cc.Args
// The first parameter is occasionally the receiver.
