// Assembly function for runtime_test.TestStartLineAsm.

//

// Note that this file can't be built directly as part of runtime_test, as assembly

// files can't declare an alternative package. Building it into runtime is

// possible, but linkshared complicates things:

//

// 1. linkshared mode leaves the function around in the final output of

// non-test builds.

// 2. Due of (1), the linker can't resolve the callerStartLine relocation

// (as runtime_test isn't built for non-test builds).

//

// Thus it is simpler to just put this in its own package, imported only by

// runtime_test. We use ABIInternal as no ABI wrapper is generated for

// callerStartLine since it is in a different package.
