Call generic methods in IL is broken
When I call generic method in IL, it just becomes something like call /* 2B000001 */
.
What I wrote:
.class public C
{
.method public static void M<+ .ctor class ([System.Runtime]System.Int32) T>()
{
ret
}
.method public static void M()
{
.entrypoint
call void C::M<int64>()
ret
}
}
What it output:
.class public auto ansi C
extends [mscorlib]System.Object
{
// Methods
.method public static
void M<class .ctor ([System.Runtime]System.Int32) +T> () cil managed
{
// Method begins at RVA 0x2050
// Code size 1 (0x1)
.maxstack 8
IL_0000: ret
} // end of method C::M
.method public static
void M () cil managed
{
// Method begins at RVA 0x2054
// Code size 6 (0x6)
.maxstack 8
.entrypoint
IL_0000: call /* 2B000001 */
IL_0005: ret
} // end of method C::M
} // end of class C
public class C
{
public static void M<out T>() where T : class, int, new()
{
}
public static void M()
{
//Discarded unreachable code: IL_0005
/*Error: Read out of bounds.*/;
}
}
The method is just gone. But it can be compiled when I switch the branch to x64, .NET Framework (x64) and Default at the first time (switch to other branch and switch back).
