A64 ASM
Сегодня мы напишем минимальный ассемблер для компиляции объектного кода, который получается на выходе clang от компиляции C-шной программы Hello World.
Возможно первый формальный гипервизор который будет написан на Эрланге или на подобии Эрланга будет написан с использованием этого ассеблера. Как вы знаете LLVM совершенно не поддаётся нужнам верификации так как его спецификация очень громоздкая. Гланая мотивация этой работы снизить количественные рамки формализации ассемблирования. Благодаря встроенному синтаксису Эрланга для работы с битовыми строками задача конструирования 32-битной инструкции из набора битовых строк перемнной длинны не составляет труда и может быть легко формализирована в MLTT языках.
Таким образом мы убегаем от пробелемы верифакации компилятора и переносим всю работу по оптимизации и дизайну на авторов библиотеки, которые будут строить свои функции используя компиляцию в формальный ассемблер. Такой подход в использовании MLTT язка как макросистемы для компилировать один из перспективных методов формальной верификации, который в отличие от VST и других сложных путей верификации, позволяет насладиться минималистичностью и по дороге убрать все ненужные слои абстрации включая MIR и LLVM и использовать векторную компиляция в NEON как это формально делает система Spiral, только намного лайтовее.
Начнём с простого, с Hello World:
#include <stdio.h>
int main( ) {
printf("Hello, world!\n");
}
Откомпилируем это под ARM64 на вашем Macbook и посмотрим, что получилось:
$ clang -isysroot $(xcrun --sdk iphoneos --show-sdk-path) \
-arch arm64 asm.c -o asm.o
Ассемблеровский текст результата (без меток, адресов и хекса) сохраняем в фафл asm.s.
$ objdump -disassemble asm.o

100007f70: ff 83 00 91 add sp, sp, #32
100007f74: c0 03 5f d6 ret
Хотим в распарсаном виде иметь такой стрим (в основном всё из атомов, так как они меньше всего загрязняют эрланг синтаксис):
[{sub,sp,sp,32},
{stp,x29,x30,[sp,16]},
{add,x29,sp,16},
{adrp,x8,0}
{add,x8,x8,4008},
{mov,w0,0},
{stur,w0,[x29,-4]},
{mov,x0,x8}
{bl,[24,'0x100007f78']},
{ldur,w9,[x29,-4]},
{mov,x0,x9},
{ldp,x29,x30,[sp,16]},
{add,sp,sp,32}
{ret}]
Попробуем написать парсер этого асм стрима:
atom("#"++X) -> list_to_integer(X);
atom(X) -> list_to_atom(X).
last(X,Y,A) ->
case lists:reverse(X) of
"]"++Z -> [lists:reverse([atom(lists:reverse(Z))|Y])|A];
_ -> {[atom(X)|Y],A} end.
code(Bin) ->
[ lists:reverse(
lists:foldl(
fun([$[|X],A) -> last(X,[],A);
(X,{Y,A}) -> last(X,Y,A);
(X,A) -> [atom(X)|A] end,[],string:tokens(C," ,")))
|| C <- string:tokens(binary_to_list(Bin),"\n") ].
compile(Code) ->
{0,iolist_to_binary([ success(?MODULE,hd(I),tl(I)) || I <- Code])}.
Теперь представим как выглядит компиляция первых инструкций (для 32-битных и 64-битных регистров). Приводим тут только кейс для 64-битных регистров, но в файл аккуратно вкатываем всю доку (в предыдущей статье 60МБ-документ):
stur(R1,[R2,Im]) when ?x(R1), ?x(R2), ?imm(Im) ->
Rt = reg(R1), Rn = reg(R2), I = <<Im:9>>,
<<3:2,7:3,0:6,I/bitstring,0:2,Rn/bitstring,Rt/bitstring>>;
mov(R1,Im) when ?x(R1), ?imm(Im) ->
R = reg(R1), I = <<Im:16>>,
<<1:1,2:2,37:6,0:2,I/bitstring,R/bitstring>>;
adrp(R1,Im) when ?x(R1), ?imm(Im) ->
Dst = reg(R1), I = <<(Im bsr 2):19>>, J = <<Im:2>>,
<<1:1,J:2/bitstring,16:5,I:19/bitstring,Dst:5/bitstring>>.
sub(R1,R2,Im) when ?x(R1), ?x(R2), ?imm(Im) ->
Dst = reg(R1), Src = reg(R2), I = <<Im:12>>,
<<1:1,1:1,0:1,34:6,0:1,I/bitstring,Src/bitstring,Dst/bitstring>>;
add(R1,R2,Im) when ?x(R1), ?x(R2), ?imm(Im) ->
Dst = reg(R1), Src = reg(R2), I = <<Im:12>>,
<<1:1,0:1,0:1,34:6,0:1,I/bitstring,Src/bitstring,Dst/bitstring>>;
stp(R1,R2,[R3,Im]) when ?x(R1), ?x(R2), ?x(R3), ?imm(Im) ->
Dst = reg(R1), Src = reg(R2), Rn = reg(R3), I = <<(Im div 8):7>>,
<<2:2,5:3,0:1,2:3,0:1,I/bitstring,Src/bitstring,Rn/bitstring,Dst/bitstring>>;
Любая армовская инструкция занимает ровно 3 строчки: 1) параметры и матчинг; 2) декодирование литералов; 3) составление схемы битвектора. Я сделал так, что те инструкции которые пока не поддерживаются тихо фейлятся (success, для громкого фейла включите success_):

APPENDIX A
Here are A64 ISA main 152 cases for 11-bit pattern matching. To fulfill the gaps we'll need additional bits lookup as we do for SIMD cases.
