Is it possible to turn on/off optimizations for the .NET compiler in godbolt?
I've tried -optimize and Optimize as per the docs, and some other fruitless attempts, but I don't see a difference.
With .NET (main) it always seems to optimize. The other one (.NET 7.0.105) does not seem to (see below example). However, it does remove some duplicate code that is force inlined from different source functions (when comparing with a hand-optimized version). This confuses me; are such optimizations done even in debug?
static int Test(int a)
{
a = a+2;
a = a+2;
return a;
}
.NET (main):
MyClass:Test(int):int (FullOpts):
lea eax, [rdi+0x04]
ret
.NET 7.0.105:
MyClass:Test(int):int:
add edi, 2
add edi, 2
mov eax, edi
ret
