From eb169ea5a89909b90794e0388f89d6d372754e46 Mon Sep 17 00:00:00 2001 From: Nao Pross Date: Thu, 5 Oct 2017 16:09:59 +0200 Subject: Move test units to z80/tests, and drivers are now statically linked Makefiles for the test units were getting messier, so now drivers (that need to be tested) are statically compiled in their own folder under z80/drivers. The kernel makefile and is now broken since everything has been moved. --- sw/z80/TODO.txt | 1 + sw/z80/arch/addresses.h | 15 ++ sw/z80/coding_rules.txt | 120 ---------- sw/z80/crt0.rel | 86 -------

-1,120 +0,0 @@ -CODING STYLE FOR THIS PROJECT -============================= - -In order to have a consistent codebase, there are the following rules on -writing code in C (and assembly). For the most part they are similar to the -Linux kernel coding rules by Torvalds. - -PROGRAM LOGIC -------------- -I expect a certain level of common sense from people so I won't mention the -super-basic stuff. But I would like to point out a few thing I WON'T accept -(unless there is a valid reason and an explanation of why). First, I believe -that code has to be aesthetically pleasing to watch and with a clear logic -flow so: - - - Avoid deeply nested code and recursive black magic - - - No special cases: generally the code of a function should behave the - same with any argument. Avoid horrible exceptions for magic values - - - No extreme modularization: do not write code that is extremely - encapsulated with dozens of helper functions to control every signal - that runs through the damn motherboard - -EDITOR (SPACES > TABS) ----------------------- -You can use your favourite editor but spaces are better than tabs, no -discussion. For this project every source file must have an indent of 4 -spaces. Since 80 characters is the standard terminal width, the code has to be -hard wrapped at 80, 78 or 72 characters. Also there shouldn't be any markup on -the source code for your editor, not even in the comments; just the code. - - - use spaces, 1 indent - 4 spaces - - hard wrap at 80 / 78 / 72 characters - - no markup for folds or any other editor specific feature - - -C CODE INDENT AND BRACES ------------------------- -I personally prefer the K&R coding style because it was used in 'The C -Programming Language' book from Dennis Ritchie which is the 'standard' for -learning C. But I also like Linus' kernel coding rules, so sometimes I might -use some of his rules. Anyway, you can look them up if you want to or just -look at the following example that sums most of the important stuff. - - - K&R braces and function prototypes - - snake_case for variables and function names - - pointer asterisk in front of the variable ( ex: int *p; ) - -Here's a short example that uses most of the stuff: - - #include - #include - - #define MY_DEVICE_MEMORY_ADDR 0x5020 - - #define MY_DEVICE_FLAG_RDY 1 - #define MY_DEVICE_FLAG_ERR 2 - - // same for unions - struct my_device - { - volatile uint8_t buffer; - volatile uint8_t flags; - } *_my_dev = (struct my_device *) MY_DEVICE_MEMORY_ADDR; - - - int my_device_write(uint8_t *data, size_t size); - - /* This is the main function - * and this is a multiline comment to explain something if needed - */ - int main(int argc, char *argv[]) - { - int i; - int j = 0; - uint8_t data[2] = { 0xFF, 0xAB }; - const char *string = "My magic string"; - - while (j < 100) { - j++; - } - - printf("%s\n", string); - - if (some_condition) { - // inline comment - } else { - my_device_write(data, 2);
