The names stand for Oreo's Brainfuck Interpreter and Oreo's Brainfuck
Compiler, separate tasks that shouldn't be packaged in one executable.
|
|
Provides:
+ Transpilation from brainfuck code into intel style assembly
+ functions to assemble and link code
|
|
No need to interpret "multiple files in sequence". Just execute the
one file given.

RELEASE and DEBUG builds have differing build flags, triggered by
setting RELEASE variable. No longer doing object based compilation
because:
+ gcc is fast enough without it
+ stale code compilation bugs are annoying
+ having one output binary to clean-up is just easier when switching
build-types

Flag which provides some helpful messages for debugging.

Really easy implementation considering opcodes are super simple. I
was right to implement the loop_ref system so at parse time we have
resolved references and don't need to do it at runtime (helps with
compilation I guess as well).
|
|
Same principle as main->lib (previous commit).
|
|
lib.(h|c) basically has structures and functions I no longer want to
stare at in main.c
|

Now you can use command line arguments to list a set of input files
for the interpreter to use.
Currently outputs the data parsed per file.

Apparently you can't just `fseek` because it's "not portable" and
"deeply offensive" or whatever, so here's a really dirty chunk based
allocator which uses `fread` to just read chunks of data at a time and
basically runs around this issue.
While it's slower than an fseek solution for general files, this
solution allows pipes and other _weird_ things that count as "files"
to just werk.
|
|
Using a buffer structure allows me to pass more information to
callers and a bit more discretion over how data is passed.
Better error reporting via having a file handle and reporting it
Emacs/GCC style.

Simple parser, took like an hour.
Not very smart but at least it's like O(n).
