it's like 33%/33%/33% if I'm going to spend this weekend: * putting together shelves * writing a bison/yacc parser for flags * hacking on the Merlin (BBC) DS game

my life is weird

[kremlin]

forgive me for the questions & any possible inconsistencies or malformations:

how do we compile our symbolic high/low level code into machine language, and how do we find the most efficient method of conversion from symbolic to machine code?

is it possible to include things from asm in C source code?

why do any of the abstractions in C mean anything? how does the compiler translate them?

would it be possible to write and compile a libc in C on a machine which didn't have a precompiled libc? i think the answer is no, so how much peripheral stuff would you need to pull it off?

are these things i could have figured out by just reading the one compiler book with the dragon on the cover?

thanks and apologies.

these are uhh. these are really good questions. like if you're asking these then i think you know way more than you think you do

how do we compile our symbolic high/low level code into machine language?

we do it the natural (only?) way, using parsers, although a bit more technically involved than just a parser. all programming languages are comprised of just keywords (e.g. int, static, enum, if, etc) and operators(+, -, *, %), those are the only reserved terms. everything between them is an identifier (name of variable, struct, etc), so at some level we can just search for the reserved terms and match them, and match whatever is between them as identifiers (var names or whatever). with this, we can tokenize the raw input put it in the context of a defined grammar.

lex is the name of the program that does this. you have simple, defined keywords, and defined operators, and you group them together a few categories (e.g. int, float, long might all fall under the same "variable qualifier" category"). this is tokenization.

those tokens are given to another program, yacc, which deals with it in the context of some context-free defined grammar you've also provided it. this would be a very strict and unambiguous definition of what C code is, defining things like "qualifiers like int and float always proceed an identifier, the addition (+) operator needs two operands, but the ++ (increment by 1) operator only needs one". yacc processes these tokens in the context of the defined grammar, and since those tokens are defined in broad categories, you can start to converge on a method of generating machine code for them.

how do we find the most efficient method of conversion from symbolic to machine code?

ehehehe. ill save this one for later

is it possible to include things from asm in C source code?

yes:

assembly (which translates directly 1-to-1 to machine code) is the only thing a CPU understands, so there has to be a link between the lowest level programming language and assembly at some point. it works about as you'd expect. that asm() block just gets plopped into the ELF right as it appears in the code. there are some features that allow passing C variables in/out of asm() blocks.

why do any of the abstractions in C mean anything? how does the compiler translate them?

hoping above answers this

would it be possible to write and compile a libc in C on a machine which didn't have a precompiled libc? i think the answer is no, so how much peripheral stuff would you need to pull it off?

yes, and in fact, the litmus test that divides "goofy idea some excited kid thought up and posted all over hacker news" and "real programming language" is whether or not that language is bootstrapped, which is whether or not its compiler is written in "itself". e.g. gcc & clang are both C compilers, and they are written in C. bootstrapping is the process of doing this initially. kind of a chicken-and-egg problem, but you just use external things, other languages, or if it is 1970s, direct assembly itself, to create an initial compiler for that language, and the write a compiler for that language in that language, feed it to the intermediate compiler, and bam.

its really hard to do all of this. really hard. lol

are these things i could have figured out by just reading the one compiler book with the dragon on the cover?

idk which one that is

finally...

how do we find the most efficient method of conversion from symbolic to machine code?

so this is kind of an area of debate lol. starting from the bottom, there are some very simple lines of code that directly map to machine code, e.g

a = b + c;

this would just translate to e.g. sparc

add %L1,%L2,%L3 !

if statements would map to branch instructions, etc, etc. pretty straightforward. but there are higher-order optimizations that modern compilers will do, for example, the compiler might see that you write to a variable but never read from it again, and realize since that memory is never read again, you may as well not even bother writing it in the first place, since it won't matter. and then choose to just not include the now-deemed-unnecessary instructions that store whatever values to memory even though you explicitly wrote it in the source code. some of the times this is fine and yields slightly faster code, but other times it results in the buffer you used for your RSA private key not being bzero'd out and me reading it while wearing a balaclava.

Lab 8: Introduction to Lex/Yacc (Flex/Bision)

Aim: The goal of this lab is to introduce the use of Lex (Flex) and Yacc (Bison) for building scanners and parsers Let’s get started! Create a directory structure to hold your work for this course and all the subsequent labs: Suggestion: CS202/Lab8 A bit more detailed description of Lex and Yacc is provided in LexAndYaccTutorial.pdf on Moodle Introduction When properly used, Lex & Yacc allow…

近年、Linuxやcygwinの普及によってだれでもyacc/lexを使って新しい言語を作成し、その処理系を作成することができるようになってきた。 G・フリードマンの「Cコンパイラ設計」は、yacc/lexの使い方を丁寧に説明した名著であるが、英語の原本も日本語本も絶版で、amazonのオークションでも買えないため日本語訳本を借り、OCRから復刻することにした。
