+Let's say you have a file compiled with `-g` on the IDO compiler, that looks like this: +```c +float func4(void) { + "func4"; + return 0.2f; +} +``` + +This script enables replacing it by: +```asm +GLOBAL_ASM( +.rdata +.word 0x66756e63 # func +.word 0x34000000 # 4\0\0\0 + +.late_rodata +glabel rv +.word 0x3e4ccccd # 0.2f + +.text +glabel func4 +lui $at, %hi(rv) +jr $ra +lwc1 $f0, %lo(rv)($at) +jr $ra +nop +jr $ra +nop +) +``` + +To compile the file, run `python3 build.py $CC -- $AS $ASFLAGS -- $CFLAGS -o out.o in.c`, where $CC points to an IDO binary (5.3/7.1 and recomp/qemu all supported), $AS is e.g. `mips-linux-gnu-as`, $ASFLAGS e.g. `-march=vr4300 -mabi=32` and $CFLAGS e.g. `-Wab,-r4300_mul -non_shared -G 0 -Xcpluscomm -g`. build.py may be customized as needed. + +In addition to an .o file, build.py also generates a .d file with Makefile dependencies for .s files referenced by the input .c file. +This functionality may be removed if not needed. + +Reading assembly from file is also supported, by either `GLOBAL_ASM("file.s")` or `#pragma GLOBAL_ASM("file.s")`. + +### What is supported? + +`.text`, `.data`, `.bss` and `.rodata` sections, `.word`/`.incbin`, `.ascii`/`.asciz`, and `-g`, `-g3`, `-O1`, `-O2`, `-framepointer` and `-mips1`/`-mips2` flags to the IDO compiler. + +### What is not supported? + +* complicated assembly (.ifdef, macro declarations/calls other than `glabel`, pseudo-instructions that expand to several real instructions) +* non-IDO compilers +* `-O3` (due to function reordering) + +C `#ifdef`s only work outside of `GLOBAL_ASM` calls, but is otherwise able to replace `.ifdef`. + +### What's up with "late rodata"? + +The IDO compiler emits rodata in two passes: first array/string contents, then large literals/switch jump tables. + +Data declared within `.rdata`/`.section .rodata` will end up in the first half, and `.late_rodata`/`.section .late_rodata` in the second half. + +### How does it work? + +It's a bit of a hack! +The basic idea is replace `GLOBAL_ASM` blocks with dummy C functions/global vars of the same sections sizes as the assembly. +Then the C file gets compiled, and the dummy contents overwritten with the injected assembly. + +To accomplish this, asm-processor has logic for guessing the size of assembly contents +(which assumes the assembly isn't too complicated, e.g. no macros), +and for emitting C code of exact sizes for a bunch of different IDO compiler flags. + +The assembler code is padded with nops to line it up with its correct position in the C; +this allows C and asm ELF files to be merged easily without having to fix up e.g. symbol addresses. + +The most difficult part is `late_rodata`, which is hard to create programmatically. +asm-processor does that by emitting code that uses dummy float literals/double literals/jump tables, +assembles the late_rodata at another location of the .rodata section, then overwrites the dummy rodata. +This does require some movement of symbols and relocations, and quite a bit of care in what code to +emit and how to preserve .double alignment. + +It's worth noting some alternative ways in which asm-processor would have been implemented: +- One idea to get rid of the C/asm size estimations is to emit arbitrary code, and then move code, +symbols and relocations to the correct place after the sizes are known. +Given the machinery for `late_rodata` this wouldn't have been too difficult, and it would have the upside of improved portability. +There is a big downside, however: using dummy code of incorrect size throws off alignment and can introduce unintended padding. +Fixing this would require running multiple passes of asm-processor, with one compile per `ASM_GLOBAL`. +- Another idea is to run the compiler with -S to emit assembly, modify the emitted assembly, then run the assembler +(which in IDO's case may perform additional instruction reordering etc.). +This option has not been investigated in much detail, and would perhaps be superior to the current implementation. +It does have a few unknowns to it, e.g. instruction encoding differences between GNU `as` and IDO's assembler, +how to avoid reordering the injected assembly, and how .rodata/.late_rodata are implemented. + +### Testing + +There are a few tests to ensure you don't break anything when hacking on asm-processor: `./run-tests.sh` should exit without output if they pass, or else output a diff from previous to new version. + +Tests need the environment variable `MIPS_CC` set to point to the IDO 7.1 compiler, with Pascal support enabled. + +For example if asm-processor is cloned in the same directory as [ido static recomp](https://github.com/decompals/ido-static-recomp) and the working directory is asm-processor, tests can be run using: + +```sh +MIPS_CC=../ido-static-recomp/build/7.1/out/cc ./run-tests.sh +``` + +Or using [qemu-irix](https://github.com/zeldaret/oot/releases/tag/0.1q) (don't forget `chmod u+x qemu-irix`) to emulate IDO: + +```sh +MIPS_CC='./qemu-irix -silent -L ../ido-static-recomp/ido/7.1/ ../ido-static-recomp/ido/7.1/usr/bin/cc' ./run-tests.sh +``` + +To skip running Pascal tests, remove the `tests/*.p` glob from `run-tests.sh`. diff --git a/tools/asm-processor/add-test.sh b/tools/asm-processor/add-test.sh new file mode 100755 index 0000000..708548e --- /dev/null
