"Релиз компилятора PCC 1.1.0, распространяемого под лицензией..." Отправлено Аноним, 30-Дек-14 01:28
>> Это продолжение жизни древнего компилятора (более древнего, чем GCC). > Ходили слухи, что GCC - форк PCC Сам RMS утверждает что это совсем не так. Дословно "I concluded I would have to write a new compiler from scratch. That new compiler is now known as GCC". > Hoping to avoid the need to write the whole compiler myself, I obtained the source code for the Pastel compiler, which was a multi-platform compiler developed at Lawrence Livermore Lab. It supported, and was written in, an extended version of Pascal, designed to be a system-programming language. I added a C front end, and began porting it to the Motorola 68000 computer. But I had to give that up when I discovered that the compiler needed many megabytes of stack space, and the available 68000 Unix system would only allow 64k. > I then realized that the Pastel compiler functioned by parsing the entire input file into a syntax tree, converting the whole syntax tree into a chain of "instructions", and then generating the whole output file, without ever freeing any storage. At this point, I concluded I would have to write a new compiler from scratch. That new compiler is now known as GCC; none of the Pastel compiler is used in it, but I managed to adapt and use the C front end that I had written. Процитировано с википедии
