+// The following functions allow calling the clang-compiled race runtime directly
+// from Go code without going all the way through cgo.
+// First, it's much faster (up to 50% speedup for real Go programs).
+// Second, it eliminates race-related special cases from cgocall and scheduler.
+// Third, in long-term it will allow to remove cyclic runtime/race dependency on cmd/go.
+
+// A brief recap of the ppc64le calling convention.
+// Arguments are passed in R3, R4, R5 ...
+// SP must be 16-byte aligned.
+
+// Note that for ppc64x, LLVM follows the standard ABI and
+// expects arguments in registers, so these functions move
+// the arguments from storage to the registers expected
+// by the ABI.
+
+// When calling from Go to Clang tsan code:
+// R3 is the 1st argument and is usually the ThreadState*
+// R4-? are the 2nd, 3rd, 4th, etc. arguments
+
+// When calling racecalladdr:
+// R8 is the call target address
+
+// The race ctx is passed in R3 and loaded in
+// racecalladdr.
+//
+// The sequence used to get the race ctx:
+// MOVD runtime·tls_g(SB), R10 // Address of TLS variable
+// MOVD 0(R10), g // g = R30
+// MOVD g_racectx(g), R3 // racectx == ThreadState
