Perhaps. JIT compiler has to care deeply for compilation time. For AOT compiler compilation time is a little bit less pressing problem which leaves some space for optimization passes that take too long for JIT.

In the second case it's AOT (ahead of time) not JIT (just in time) compiler.

You probably mean strcat() (which should really not be used, since now there is strncat()), there is no concat() in standard C library. strcat() does not intercept syntax of operation that does not mutate its arguments in any other context

To which the same argument applies.

Another thing that does not seem to be very constructive is complaining about all those kernels written in evil C instead of writing one in Rust.

With clang you can use -Rpass family of flags to get information about missed and used optimization opportunities. Although it will not print absolutely everything (trivial optimizations will be omitted). Other compilers have other options,

Yeah, the closer analogy would be FedEx selling information about content of your packages unless they are shipped in some kind of locked strong box.

Well, it could just use function name and leave it to javac/kotlin/other JVM front end to handle overloads and generate unique names. Although that wouldn't work nice with refection and other run-time features I guess.

The article describes Dalvik which is different from JVM, so it's not really a proof. But you are actually right. It looks that JVM bytecode includes full function signature in function invocation: https://www.ibm.com/d

by mbel 10y ago
According you your link JVM does not support this feature. It's implemented by Kotlin itself. I guess it's probably some kind of name-mangling scheme.

Compiling X to C and then C to assembly is not more complex that compiling X straight to assembly. In your orignal comment you wrote that the complexity of such setup is bigger, to which I responded: no, not really. Yes, C was not designe

Of course metadata is lost if not encoded anywhere on the way. The argument was made regarding code generation being more complex when code is saved on the intermediate level.

You are arguing that no language X is safer than writing program manually in Y when program in X is compiled to Y. Because compiler from X to Y may have bugs. Therefore no code written in Rust (X) executed on x86 CPU (Y) is safer than manua

by mbel 10y ago
This is simply not true. C in this case is just an intermediate representation of the source program. Going through multiple intermediate representation of the source code is fairly standard practice when compiling anything. If anything it

by mbel 10y ago
So no code is safe? All code before execution has to be lowered to some evil, unsafe language, most commonly the assembly language of targeted CPU. The mystical process of "programmatically generating code" in also known as compil

gcc removes recursion in that case: https://godbolt.org/g/R6iBup

Yeah, it's hardly a benchmark. The information what kind of CPU they are using is also missing (why no -march=native?). Despite how unbelievable it looks, I would love to see contents of the final binary to see what is really happening

Gravitational teleport sounds like something out of cheap science-fiction novel. Magical device with pseudo scientific name which inner workings are never explained. It's only purpose is to act as a deus ex machina when author runs out
