Native AOT StackFrame method info #92869
Description
When published as a native AOT binary, System.Diagnostics.StackFrame doesn't have method information (as returned by GetMethod). Interestingly, some info is available at runtime because it is printed by ToString(). It would be preferrable to expose the module & method name via appropriate methods so that we don't have to rely on parsing ToString() output. See an example output below:
_options.LogDebug("### ToString = {0}", stackFrame.ToString());
_options.LogDebug("### Has Native Image = {0}", stackFrame.HasNativeImage());
_options.LogDebug("### Native Image Base = 0x{0:x}", stackFrame.GetNativeImageBase());
_options.LogDebug("### Native Interface pointer = 0x{0:x}", stackFrame.GetNativeIP());
_options.LogDebug("### Offset = {0}", stackFrame.GetNativeOffset());
_options.LogDebug("### FileName = {0}", stackFrame.GetFileName());
_options.LogDebug("### Line no = {0}", stackFrame.GetFileLineNumber());
_options.LogDebug("### HasMethod = {0}", stackFrame.HasMethod());
_options.LogDebug("### Method = {0}", stackFrame.GetMethod());
_options.LogDebug("### ILOffset = {0}", stackFrame.GetILOffset());ToString = System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task, ConfigureAwaitOptions) + 0x4b at offset 75 in file:line:column <filename unknown>:0:0
Has Native Image = True
Native Image Base = 0x7ff7ee540000
Native Interface pointer = 0x7ff7ee6cfb7b
Offset = 75
FileName =
Line no = 0
HasMethod = False
Method =
ILOffset = -1
As a side note, how does runtime resolve the method name in ToString() to such a nicely-looking string? If I try to symbolicate via the native debug info in the generated .PDB, the symbol name I get is S_P_CoreLib_System_Runtime_CompilerServices_TaskAwaiter__HandleNonSuccessAndDebuggerNotification
