9 // This file contains the declaration of the MCPseudoProbe to support the pseudo
10 // probe encoding for AutoFDO. Pseudo probes together with their inline context
11 // are encoded in a DFS recursive way in the .pseudoprobe sections. For each
12 // .pseudoprobe section, the encoded binary data consist of a single or mutiple
13 // function records each for one outlined function. A function record has the
14 // following format :
15 //
16 // FUNCTION BODY (one for each outlined function present in the text section)
17 // GUID (uint64)
18 // GUID of the function
19 // NPROBES (ULEB128)
20 // Number of probes originating from this function.
21 // NUM_INLINED_FUNCTIONS (ULEB128)
22 // Number of callees inlined into this function, aka number of
23 // first-level inlinees
24 // PROBE RECORDS
25 // A list of NPROBES entries. Each entry contains:
26 // INDEX (ULEB128)
27 // TYPE (uint4)
28 // 0 - block probe, 1 - indirect call, 2 - direct call
29 // ATTRIBUTE (uint3)
30 // 1 - reserved
31 // ADDRESS_TYPE (uint1)
32 // 0 - code address, 1 - address delta
33 // CODE_ADDRESS (uint64 or ULEB128)
34 // code address or address delta, depending on ADDRESS_TYPE
35 // INLINED FUNCTION RECORDS
36 // A list of NUM_INLINED_FUNCTIONS entries describing each of the inlined
37 // callees. Each record contains:
38 // INLINE SITE
39 // ID of the callsite probe (ULEB128)
40 // FUNCTION BODY
41 // A FUNCTION BODY entry describing the inlined function.
