| -- This package provides exported subprograms to be called at debug time to |
| -- measure stack usage at run-time. |
| |
| -- Note: this package must be a child package of System.Stack_Usage to have |
| -- visibility over its private part; it is however part of GNARL because it |
| -- needs to access tasking features via System.Tasking.Debug and |
| -- System.Task_Primitives.Operations; |
| |
| package System.Stack_Usage.Tasking is |
| |
| procedure Report_All_Tasks; |
| -- Print the current stack usage of all tasks on stderr. Exported to be |
| -- called also in debug mode. |

| -- also in debug mode. |
