TrustJIT
This is it, Madeline.
Just trust jit.
Why are you so nervous?
sometimes the first benchmark may be faster or slower, i added two empty benchmark.
All methods have 7 parameters and is static.
the methods without Simulate prefix is hooked. all the hooks do nothing.
Simulate* is not hooked, but is indirectly called to simulate the hook.
Instanced is hooked by instanced hook.
Static is hooked by static hook.
Aggressive is hooked by a instanced and AggressiveInlining hook.
No is hooked by a instanced and NoInlining hook.
