Understanding Garbage Collection in .net

affected by having a debugger present. First off the jitter performs two important duties when it compiles the IL for a.. duration of the program that would amount to a leak. The jitter can use the table to discover that such a local variable is.. being used by such code since it wasn't compiled by the jitter so doesn't have the table that says where to look for the reference...

Structs versus classes

Performance differences between debug and release builds

make better decisions. It is a big deal in the x86 jitter because it has so few registers to work with. Having it select.. program. It does happen however. Both the x64 and the x86 jitters have had problems with structs. The x86 jitter has trouble.. the x86 jitters have had problems with structs. The x86 jitter has trouble with floating point consistency producing subtly..

A reproducable example of volatile usage

http://stackoverflow.com/questions/6164466/a-reproducable-example-of-volatile-usage

this question The exact semantics of volatile is a jitter implementation detail. The compiler emits the Opcodes.Volatile.. really happens. Declaring a variable volatile prevents the jitter optimizer from optimizing the code to store the variable in.. is hanging. This will only happen with the current x86 jitter another strong hint that volatile is really a jitter implementation..

When should the volatile keyword be used in C#?

http://stackoverflow.com/questions/72275/when-should-the-volatile-keyword-be-used-in-c

means not only make sure that the compiler and the jitter do not perform any code reordering or register caching optimizations..

Casting a result to float in method returning float changes result

http://stackoverflow.com/questions/8795550/casting-a-result-to-float-in-method-returning-float-changes-result

to be produced instead of an infinity. The C# compiler the jitter and the runtime all have broad lattitude to give you more accurate.. and 4.0 runtimes the difference is clearly that in 4.0 the jitter chooses to go to higher precision in your particular case and.. go to higher precision in your particular case and the 3.5 jitter chooses not to. That does not mean that this situation was impossible..

How is Math.Pow() implemented in .Net Framework?

http://stackoverflow.com/questions/8870442/how-is-math-pow-implemented-in-net-framework

the FCIntrinsic macro in the table. That's a hint that the jitter may implement the function as an intrinsic. In other words substitute..

Why is OfType<> faster than Cast<>? [closed]

http://stackoverflow.com/questions/11430570/why-is-oftype-faster-than-cast

I'm not sure if this is necessary but I think it means the JITter generates code beforehand rather than while we're timing Perform..

Is there a way to see the native code produced by theJITter for given C# / CIL?

http://stackoverflow.com/questions/1945719/is-there-a-way-to-see-the-native-code-produced-by-thejitter-for-given-c-sharp

there a way to see the native code produced by theJITter for given C# CIL In a comment on this answer which suggests.. I would now like to see the actual x86 assembler that the JITter produces but I have no idea how to do this. Is it even possible.. were enlightening to say the least it turns out the JITter can actually do arithmetic Here's edited samples from the Disassembly..

Performance overhead for properties in .NET

Preventing JIT inlining on a method

Are floating-point numbers consistent in C#? Can they be?

How long does it take to invoke an empty function?

Try-catch speeding up my code?

http://stackoverflow.com/questions/8928403/try-catch-speeding-up-my-code

the problematic code generation path is avoided when the JITter knows that the block is in a try protected region. This is pretty.. region. This is pretty weird. We'll follow up with the JITter team and see if we can get a bug entered so that they can fix.. for the duration of the activation. We believe that the JITter will be able to do a better job of register allocation and whatnot..
