[PATCH] D91756: [CSSPGO] Pseudo probes for function calls.

[Wei Mi via Phabricator via llvm-commits]

wmi added inline comments.


================
Comment at: llvm/include/llvm/IR/PseudoProbe.h:33-34
+  static uint32_t packProbeData(uint32_t Index, uint32_t Type) {
+    assert(Index <= 0xFFFF);
+    assert(Type <= 0x7);
+    return (Index << 3) | (Type << 26) | 0x7;
----------------
Add assertion messages here and the other places.


================
Comment at: llvm/lib/Transforms/IPO/SampleProfileProbe.cpp:136-138
+  for (auto &I : CallProbeIds) {
+    auto Call = I.first;
+    uint32_t Index = I.second;
----------------

Ah, right. I mistakenly remember I saw that somewhere in llvm codebase. llvm coding standard says we should use c++14.
