Go with an existing educational language instead, and focus on learning about compilers. The following two are specifically designed for classroom use in compiler courses and by extension are great for a hobby compiler project. ChocoPy. ChocoPy is a concise Python subset, which can be implemented in a time-frame reasonable for a hobby compiler.

2011年6月16日 · A "compiler" is any device that translates from one programming language to another. One of the nice things about having a C# compiler that turns C# into IL, and an IL compiler (the "jitter") that turns IL into machine code, is that you get to write the C# compiler to IL (easy!), and put the processor-specific optimizations in the jitter.

I've seen several compiler bugs, reported a few myself (specifically, in F#). That said, I think compiler bugs are rare because people who write compilers are generally very comfortable with the rigorous concepts of computer science that make them really conscious about the mathematical implications of code.

2015年6月12日 · in the above, the compiler can choose to keep right on statically inlining, from InlineMe through whatever's inside act(), nor a need to touch any vtables at runtime. But any uncertainty in what flavor of object will leave it as a call to a discrete function, even if some other invocations of the same function are inlined.

2016年9月8日 · So, in one compiler a pragma is used and in another a keyword, both to accomplish the modification of the declaration (and both as extensions, though the keyword version actually extends the language grammar whereas the pragma version fits within existing language grammar). In this case, neither involves an intrinsic function.

2015年7月30日 · So when the compiler reaches x + y, instead of running lots of code that branches for many different types of x and y, the compiler quickly checks if we have strings again, and then executes just a few lines of machine code that specifically concatenate strings.

The tcc compiler (i.e. TinyCC) is quite small (a few dozens of thousand lines of C code) and the executable (on x86-64) is about 190Kbytes. But on current processors, you need an optimizing compiler to get most of the performance from the compiled executable code.

2015年4月17日 · The compiler lacks information that is available at run-time. The idea that the compiler, with plenty of time available, can do a better job of scheduling memory accesses than hardware can at run-time is wrong. It would be true for single-core, single-hardware-thread machines without processor caches.

Usually this starts with the development of a 'cross compiler' on a known architecture to compile C for the new architecture. (the compiler, itself, can be what is being compiled, from source, for the new architecture.) even a related new architecture needs lots of updates to the compiler to take advantage of the new architecture.

2016年7月12日 · Writing it in a higher level language might have been faster, but there were performance considerations (an assembler used as a back end to a compiler, particularly, needs to be very fast in order to prevent slowing the compiler down too much, as it can end up handling very large amounts of code, and this was a use case that we specifically ...
