Sets a code map for the specified function using the specified Microsoft intermediate language (MSIL) map entries.
In the .NET Framework version 2.0, calling SetILInstrumentedCodeMap on a FunctionID that represents a generic function in a particular application domain will affect all instances of that function in the application domain.
HRESULT SetILInstrumentedCodeMap( [in] FunctionID functionId, [in] BOOL fStartJit, [in] ULONG cILMapEntries, [in, size_is(cILMapEntries)] COR_IL_MAP rgILMapEntries);
A profiler often inserts statements within the source code of a method in order to instrument that method (for example, to notify when a given source line is reached). SetILInstrumentedCodeMap enables a profiler to map the original MSIL instructions to their new locations. A profiler can use the ICorProfilerInfo::GetILToNativeMapping method to get the original MSIL offset for a given native offset.
The debugger will assume that each old offset refers to an MSIL offset within the original, unmodified MSIL code, and that each new offset refers to the MSIL offset within the new, instrumented code. The map should be sorted in increasing order. For stepping to work properly, follow these guidelines:
Do not reorder instrumented MSIL code.
Do not remove the original MSIL code.
Include entries for all the sequence points from the program database (PDB) file in the map. The map does not interpolate missing entries. So, given the following map:
(0 old, 0 new)
(5 old, 10 new)
(9 old, 20 new)
An old offset of 0, 1, 2, 3, or 4 will be mapped to new offset 0.
An old offset of 5, 6, 7, or 8 will be mapped to new offset 10.
An old offset of 9 or higher will be mapped to new offset 20.
A new offset of 0, 1, 2, 3, 4, 5, 6, 7, 8, or 9 will be mapped to old offset 0.
A new offset of 10, 11, 12, 13, 14, 15, 16, 17, 18, or 19 will be mapped to old offset 5.
A new offset of 20 or higher will be mapped to old offset 9.
