# Synacor Challenge
Solution to the [Synacor Challenge](https://challenge.synacor.com/)
## Building
You will need GLFW, SDL2, and OpenGL installed to build the project.

arch-spec

@ -0,0 +1,79 @@
== Synacor Challenge ==
In this challenge, your job is to use this architecture spec to create a
virtual machine capable of running the included binary. Along the way,
you will find codes; submit these to the challenge website to track
your progress. Good luck!
== architecture ==
- three storage regions
- memory with 15-bit address space storing 16-bit values
- eight registers
- an unbounded stack which holds individual 16-bit values
- all numbers are unsigned integers 0..32767 (15-bit)
- all math is modulo 32768; 32758 + 15 => 5
== binary format ==
- each number is stored as a 16-bit little-endian pair (low byte, high byte)
- numbers 0..32767 mean a literal value
- numbers 32768..32775 instead mean registers 0..7
- numbers 32776..65535 are invalid
- programs are loaded into memory starting at address 0
- address 0 is the first 16-bit value, address 1 is the second 16-bit value, etc
== execution ==
- After an operation is executed, the next instruction to read is immediately after the last argument of the current operation. If a jump was performed, the next operation is instead the exact destination of the jump.
- Encountering a register as an operation argument should be taken as reading from the register or setting into the register as appropriate.
== hints ==
- Start with operations 0, 19, and 21.
- Here's a code for the challenge website: hMTaBwjCpwTm
- The program "9,32768,32769,4,19,32768" occupies six memory addresses and should:
- Store into register 0 the sum of 4 and the value contained in register 1.
- Output to the terminal the character with the ascii code contained in register 0.
== opcode listing ==
halt: 0
stop execution and terminate the program
set: 1 a b
set register <a> to the value of <b>
push: 2 a
push <a> onto the stack
pop: 3 a
remove the top element from the stack and write it into <a>; empty stack = error
eq: 4 a b c
set <a> to 1 if <b> is equal to <c>; set it to 0 otherwise
gt: 5 a b c
set <a> to 1 if <b> is greater than <c>; set it to 0 otherwise
jmp: 6 a
jump to <a>
jt: 7 a b
if <a> is nonzero, jump to <b>
jf: 8 a b
if <a> is zero, jump to <b>
add: 9 a b c
assign into <a> the sum of <b> and <c> (modulo 32768)
mult: 10 a b c
store into <a> the product of <b> and <c> (modulo 32768)
mod: 11 a b c
store into <a> the remainder of <b> divided by <c>
and: 12 a b c
stores into <a> the bitwise and of <b> and <c>
or: 13 a b c
stores into <a> the bitwise or of <b> and <c>
not: 14 a b
stores 15-bit bitwise inverse of <b> in <a>
rmem: 15 a b
read memory at address <b> and write it to <a>
wmem: 16 a b
write the value from <b> into memory at address <a>
call: 17 a
write the address of the next instruction to the stack and jump to <a>
ret: 18
remove the top element from the stack and jump to it; empty stack = halt
out: 19 a
write the character represented by ascii code <a> to the terminal
in: 20 a
read a character from the terminal and write its ascii code to <a>; it can be assumed that once input starts, it will continue until a newline is encountered; this means that you can safely read whole lines from the keyboard and trust that they will be fully read
noop: 21
no operation

FindSDL2
--------
Locate SDL2 library
This module defines the following 'IMPORTED' targets:
::
SDL2::Core
The SDL2 library, if found.
Libraries should link to SDL2::Core
SDL2::Main
The SDL2main library, if found.
Applications should link to SDL2::Main instead of SDL2::Core
This module will set the following variables in your project:
::
SDL2_LIBRARIES, the name of the library to link against
SDL2_INCLUDE_DIRS, where to find SDL.h
SDL2_FOUND, if false, do not try to link to SDL2
SDL2MAIN_FOUND, if false, do not try to link to SDL2main
SDL2_VERSION_STRING, human-readable string containing the version of SDL2
This module responds to the following cache variables:
::
SDL2_PATH
Set a custom SDL2 Library path (default: empty)
SDL2_NO_DEFAULT_PATH
Disable search SDL2 Library in default path.
If SDL2_PATH (default: ON)
Else (default: OFF)
SDL2_INCLUDE_DIR
SDL2 headers path.
SDL2_LIBRARY
SDL2 Library (.dll, .so, .a, etc) path.
SDL2MAIN_LIBRAY
SDL2main Library (.a) path.
SDL2_BUILDING_LIBRARY
This flag is useful only when linking to SDL2_LIBRARIES insead of
SDL2::Main. It is required only when building a library that links to
SDL2_LIBRARIES, because only applications need main() (No need to also
link to SDL2main).
If this flag is defined, then no SDL2main will be added to SDL2_LIBRARIES
and no SDL2::Main target will be created.
Don't forget to include SDLmain.h and SDLmain.m in your project for the
OS X framework based version. (Other versions link to -lSDL2main which
this module will try to find on your behalf.) Also for OS X, this
module will automatically add the -framework Cocoa on your behalf.
Additional Note: If you see an empty SDL2_LIBRARY in your project
configuration, it means CMake did not find your SDL2 library
(SDL2.dll, libsdl2.so, SDL2.framework, etc). Set SDL2_LIBRARY to point
to your SDL2 library, and configure again. Similarly, if you see an
empty SDL2MAIN_LIBRARY, you should set this value as appropriate. These
values are used to generate the final SDL2_LIBRARIES variable and the
SDL2::Core and SDL2::Main targets, but when these values are unset,
SDL2_LIBRARIES, SDL2::Core and SDL2::Main does not get created.
$SDL2DIR is an environment variable that would correspond to the
./configure --prefix=$SDL2DIR used in building SDL2. l.e.galup 9-20-02
Created by Amine Ben Hassouna:
Adapt FindSDL.cmake to SDL2 (FindSDL2.cmake).
Add cache variables for more flexibility:
SDL2_PATH, SDL2_NO_DEFAULT_PATH (for details, see doc above).
Mark 'Threads' as a required dependency for non-OSX systems.
Modernize the FindSDL2.cmake module by creating specific targets:
SDL2::Core and SDL2::Main (for details, see doc above).
Original FindSDL.cmake module:
Modified by Eric Wing. Added code to assist with automated building
by using environmental variables and providing a more
controlled/consistent search behavior. Added new modifications to
recognize OS X frameworks and additional Unix paths (FreeBSD, etc).
Also corrected the header search path to follow "proper" SDL
guidelines. Added a search for SDLmain which is needed by some
platforms. Added a search for threads which is needed by some
platforms. Added needed compile switches for MinGW.
On OSX, this will prefer the Framework version (if found) over others.
People will have to manually change the cache value of SDL2_LIBRARY to
override this selection or set the SDL2_PATH variable or the CMake
environment CMAKE_INCLUDE_PATH to modify the search paths.
Note that the header path has changed from SDL/SDL.h to just SDL.h
This needed to change because "proper" SDL convention is #include
"SDL.h", not <SDL/SDL.h>. This is done for portability reasons
because not all systems place things in SDL/ (see FreeBSD).

FindSDL2_gfx
--------------
Locate SDL2_gfx library
This module defines the following 'IMPORTED' target:
::
SDL2::GFX
The SDL2_gfx library, if found.
Have SDL2::Core as a link dependency.
This module will set the following variables in your project:
::
SDL2_GFX_LIBRARIES, the name of the library to link against
SDL2_GFX_INCLUDE_DIRS, where to find the headers
SDL2_GFX_FOUND, if false, do not try to link against
SDL2_GFX_VERSION_STRING - human-readable string containing the
version of SDL2_gfx
This module responds to the following cache variables:
::
SDL2_GFX_PATH
Set a custom SDL2_gfx Library path (default: empty)
SDL2_GFX_NO_DEFAULT_PATH
Disable search SDL2_gfx Library in default path.
If SDL2_GFX_PATH (default: ON)
Else (default: OFF)
SDL2_GFX_INCLUDE_DIR
SDL2_gfx headers path.
SDL2_GFX_LIBRARY
SDL2_gfx Library (.dll, .so, .a, etc) path.
Additional Note: If you see an empty SDL2_GFX_LIBRARY in your project
configuration, it means CMake did not find your SDL2_gfx library
(SDL2_gfx.dll, libsdl2_gfx.so, etc). Set SDL2_GFX_LIBRARY to point
to your SDL2_gfx library, and configure again. This value is used to
generate the final SDL2_GFX_LIBRARIES variable and the SDL2::GFX target,
but when this value is unset, SDL2_GFX_LIBRARIES and SDL2::GFX does not
get created.
$SDL2GFXDIR is an environment variable that would correspond to the
./configure --prefix=$SDL2GFXDIR used in building SDL2_gfx.
$SDL2DIR is an environment variable that would correspond to the
./configure --prefix=$SDL2DIR used in building SDL2.
Created by Amine Ben Hassouna:
Adapt FindSDL_image.cmake to SDL2_gfx (FindSDL2_gfx.cmake).
Add cache variables for more flexibility:
SDL2_GFX_PATH, SDL2_GFX_NO_DEFAULT_PATH (for details, see doc above).
Add SDL2 as a required dependency.
Modernize the FindSDL2_gfx.cmake module by creating a specific target:
SDL2::GFX (for details, see doc above).
Original FindSDL_image.cmake module:
Created by Eric Wing. This was influenced by the FindSDL.cmake
module, but with modifications to recognize OS X frameworks and
additional Unix paths (FreeBSD, etc).
