By no means am I an expert in this, but I stumbled recently on what I think you want: the CoClass attribute class. [System.Runtime.InteropServices.CoClass(typeof(Test))] public interface Dummy { } A coclass supplies concrete implementation(s) of one or more interfaces. In COM, such concrete implementations can be written in any programming language that supports COM component … Read more
There’s a short overview at MinGW-w64 Wiki: Why doesn’t mingw-w64 gcc support Dwarf-2 Exception Handling? The Dwarf-2 EH implementation for Windows is not designed at all to work under 64-bit Windows applications. In win32 mode, the exception unwind handler cannot propagate through non-dw2 aware code, this means that any exception going through any non-dw2 aware … Read more
The definition you have quoted above is too general for a beginner to understand completely and so let me just simplify it to something we see practically. Compiler: is an umbrella term to describe a program that takes source code written in one language and produce a (or many) output file in some other language. … Read more
Assembly instructions are (generally) a direct mapping to opcodes, which are (multi-)byte values of machine code that can be directly interpreted by the processor. It is quite possible to write a program in opcodes directly by looking them up from a table (such as this one for the 6039 microprocessor, for example) that lists them … Read more
You can do this with make – with gnu make it is the -j flag (this will also help on a uniprocessor machine). For example if you want 4 parallel jobs from make: make -j 4 You can also run gcc in a pipe with gcc -pipe This will pipeline the compile stages, which will … Read more
The oldest version of GCC was compiled using another C compiler, since there were others when it was written. The very first C compiler ever (ca. 1973, IIRC) was implemented either in PDP-11 assembly, or in the B programming language which preceded it, but in any case the B compiler was written in assembly. Similarly, … Read more
Think of some of the problems that can occur if there is no newline. According to the ANSI standard the #include of a file at the beginning inserts the file exactly as it is to the front of the file and does not insert the new line after the #include <foo.h> after the contents of … Read more
Pythoscope does this to the test cases it automatically generates as does the 2to3 tool for python 2.6 (it converts python 2.x source into python 3.x source). Both these tools uses the lib2to3 library which is an implementation of the python parser/compiler machinery that can preserve comments in source when it’s round tripped from source … Read more
GHC Core is the System FC language into which all Haskell is translated. The (approximate) grammar for Core is given by: Core is closely related to the simpler and better known System F. All transformations GHC does on the Core level are type-preserving refactorings of this Core representation, to improve performance. And, not so well … Read more
Since the return statement terminates the execution of the current function, the two forms are equivalent (although the second one is arguably more readable than the first). The efficiency of both forms is comparable, the underlying machine code has to perform a jump if the if condition is false anyway. Note that Python supports a … Read more
