Compiler Warning (level 4) C4714
function 'function' marked as __forceinline not inlined
The given function was selected for inline expansion, but the compiler did not perform the inlining.
Although __forceinline
is a stronger indication to the compiler than __inline
, inlining is still performed at the compiler's discretion, but no heuristics are used to determine the benefits from inlining this function.
In some cases, the compiler will not inline a particular function for mechanical reasons. For example, the compiler will not inline:
A function if it would result in mixing both SEH and C++ EH.
Some functions with copy constructed objects passed by value when -GX/EHs/EHa is on.
Functions returning an unwindable object by value when -GX/EHs/EHa is on.
Functions with inline assembly when compiling without -Og/Ox/O1/O2.
Functions with a variable argument list.
A function with a
try
(C++ exception handling) statement.
The following sample generates C4714:
// C4714.cpp
// compile with: /Ob1 /GX /W4
__forceinline void func1()
{
try
{
}
catch (...)
{
}
}
void func2()
{
func1(); // C4714
}
int main()
{
}
