New Revision: 191538
URL: http://llvm.org/viewvc/llvm-project?rev=191538&view=rev
Log:
TBAA: handle scalar TBAA format and struct-path aware TBAA format.
Remove the command line argument "struct-path-tbaa" since we should not depend
on command line argument to decide which format the IR file is using. Instead,
we check the first operand of the tbaa tag node, if it is a MDNode, we treat
it as struct-path aware TBAA format, otherwise, we treat it as scalar TBAA
format.
When clang starts to use struct-path aware TBAA format no matter whether
struct-path-tbaa is no, and we can auto-upgrade existing bc files, the support
for scalar TBAA format can be dropped.
Existing testing cases are updated to use the struct-path aware TBAA format.

+// With struct-path aware TBAA, the MDNodes attached to an instruction using
+// "!tbaa" are called path tag nodes.
+//
+// The path tag node has 4 fields with the last field being optional.
+//
+// The first field is the base type node, it can be a struct type node
+// or a scalar type node. The second field is the access type node, it
+// must be a scalar type node. The third field is the offset into the base type.
+// The last field has the same meaning as the last field of our scalar TBAA:
+// it's an integer which if equal to 1 indicates that the access is "constant".
+//
+// The struct type node has a name and a list of pairs, one pair for each member
+// of the struct. The first element of each pair is a type node (a struct type
+// node or a sclar type node), specifying the type of the member, the second
+// element of each pair is the offset of the member.
+//
+// Given an example
+// typedef struct {
+// short s;
+// } A;
+// typedef struct {
+// uint16_t s;
+// A a;
+// } B;
+//
+// For an acess to B.a.s, we attach !5 (a path tag node) to the load/store
+// instruction. The base type is !4 (struct B), the access type is !2 (scalar
+// type short) and the offset is 4.

+// !2 = metadata !{metadata !"short", metadata !1} // Scalar type node
+// !3 = metadata !{metadata !"A", metadata !2, i64 0} // Struct type node
+// !4 = metadata !{metadata !"B", metadata !2, i64 0, metadata !3, i64 4}
+// // Struct type node
+// !5 = metadata !{metadata !4, metadata !2, i64 4} // Path tag node
+//
+// The struct type nodes and the scalar type nodes form a type DAG.

+// char (!1) -- edge to Root
+// short (!2) -- edge to char
+// A (!3) -- edge with offset 0 to short
+// B (!4) -- edge with offset 0 to short and edge with offset 4 to A
+//
+// To check if two tags (tagX and tagY) can alias, we start from the base type
+// of tagX, follow the edge with the correct offset in the type DAG and adjust
+// the offset until we reach the base type of tagY or until we reach the Root
+// node.
+// If we reach the base type of tagY, compare the adjusted offset with
