[Bug] Cannot combine memory operand with immediate operand
0649c3f prevents the very important possibility of combining memory operands with immediate operands. Consider choosing a random operand size to work around assembler encoding ambiguity. (Pls fix ASAP, my students need this.)
[Command suggestion] range comparison command
See #57 (comment) for reference
Quote:
The main idea is to add an ability to jump with condition so you can achieve something like this:
C
if(a > 5 && a < 20) {
// some code
}
// continueASM
cmp eax, 5
jle .LYeet0
cmp eax, 19
jg .LYeet0
# some code
.LYeet0:
# continue[Open for suggestions] `call` equivalent for MemeASM
While MemeASM already supports functions, one cannot call a function, as there is currently no command for that.
Command name ideas:
whomst have summoned the almighty one [function name]the secret ingredient is [function name]
[Bug] `who would win?`-comparisons with negative numbers result in invalid labels
Describe the bug
Negative numbers are accepted in comparisons, yet as will reject the generated labels due to a - being in them
Possible workaround: Convert parameter to Hex before translation
To Reproduce
I like to have fun, fun, fun, fun, fun, fun, fun, fun, fun, fun main
who would win? rax or -1
rax wins
-1 wins
right back at ya, buckaroo
results in the following error messages:
{standard input}: Assembler messages:
{standard input}:65: Error: junk `Wins_0' after expression
{standard input}:67: Error: unknown pseudo-op: `.l'
gcc exited unexpectedly with exit code 256. If you did not expect this to happen, please report this issue at https://github.com/kammt/MemeAssembly/issues so that it can be fixed
Line 65 being .L-1Wins_0:
Reported by @0li5Drr
[Bug] Not all return statements are accepted
Describe the bug
Some return statements do not appear to be interpreted as return statements when having multiple functions in a file.

System Info (please complete the following information):
- Linux Distribution: WSL
- GCC Version: gcc (Ubuntu 9.4.0-1ubuntu1~20.04.1) 9.4.0
- MemeASM Compiler Version: latest from develop branch
- Installation method: Makefile (
sudo make install)
[Feature] Add DWARF-support
Since stabs is only supported on Linux, MacOS and Windows currently do not support the -g-Flag
Add Debugging command
It's a trap should translate to int3, raising SIGTRAP
If a debugger is attached, this breaks into the debugger. From there, one can continue normal program execution.
Without debugger, this by default causes the running process to terminate and generates a core dump.
The compiler should print "Nice" when the numbers 69 or 420 are used in the code
[Suggestion] New compile mode: Bully mode
Since v1.4, most error messages are sort of helpful. But is that really what the user wants when coding in MemeASM? I think not.
That's why I propose to add a new compilation mode. Bully mode. It can be activated using -fcompile-mode=bully (or disabled using -fcompile-mode=noob) and changes the following:
- All compiler errors are silenced. If a command is invalid, it triggers undefined behavior:tm:. This means that it will be replaced with a random (working) command at compile time
- If the operand size of a command is unknown, a random size will be chosen (see #70)
The result is that provided code will always compile, but will in general not do what the programmer intended it to do
[Bug] Compiler Crashes when providing an empty file as input
Console Output:
Semantic Error in line 1: An executable cannot be created if no main-function exists
Floating point exception (core dumped)
[Bug] Signed Division incorrectly implemented
Describe the bug
- The signed division command uses
r8as a temporary register, regardless of whether this is the actual destination register or not. - At the end of the division, the stack pointer is misaligned, potentially leading to a segmentation fault
To Reproduce
I like to have fun, fun, fun, fun, fun, fun, fun, fun, fun, fun main
r8 is brilliant, but I like 9
look at what 3 needs to mimic a fraction of r8
right back at ya, buckaroo
[Bug] Number parameters outside of accepted range are not caught
Describe the bug
As of now, decimal numbers are just plain forwarded as-is. Yet in ASM their sizes are limited. mov has a limit of 64 Bit, while other instructions only accept values in the range of a 32 Bit signed integer. This is not checked by the compiler.
To Reproduce
One can e.g. write al is brilliant, but I like 999999999999
Check if calling nasm or gcc fails
If so, an error message should be printed
[Command suggestion] Alright. I've hacked into the mainframe and disabled their algorithms.
Command Syntax: (e.g. stonks [register])
Alright. I've hacked into the mainframe and disabled their algorithms.
Command Description:
Tries to kill init using SIGKILL.
Which x86_64 Assembly instruction(s) would be used to translate this command?
mov rdi, 1
mov rsi, 9
call kill
What could this command be useful for?
Having fun :).
What Meme is your command based on? (You can also provide a link to e.g. its KnowYourMeme page)
If you like the idea, i'd be happy to implement this in a few months, once I've got less stuff on my plate :).

[Bug] Broken writechar output command
Describe the bug
When using the what can I say except T command, the output sometimes just doesn't show up.
This is because for some reason the writechar function no longer sets rdi to 1/stdout; so it just uses whatever value was in rdi before.
It can also be seen when running the example below with strace:
execve("./main", ["./main"], 0x7fffe5d793a0 /* 28 vars */) = 0
[... irrelevant stuff...]
write(5, "T", 1) = -1 EBADF (Bad file descriptor)
write(5, "e", 1) = -1 EBADF (Bad file descriptor)
write(5, "s", 1) = -1 EBADF (Bad file descriptor)
write(5, "t", 1) = -1 EBADF (Bad file descriptor)
exit_group(0) = ?
+++ exited with 0 +++

[Bug] Semantic errors when a function contains multiple return statements
Example:
I like to have fun, fun, fun, fun, fun, fun, fun, fun, fun, fun main
who would win? eax or ebx
eax wins
What the hell happened here? eax >= ebx
I see this as an absolute win
ebx wins
What the hell happened here? eax < ebx
no, I don't think I will
In this example, exit code 0 is returned when eax is greater than or equal to ebx. If not, exit code 1 is returned. While this code is completely valid, the MemeASM compiler rejects it
Semantic Error in line 11: Statement does not belong to any function
Semantic Error in line 13: Statement does not belong to any function
This is because the analysis of a function is stopped when a return statement is found, meaning that other statements below it are ignored.
Adapt memeasm.c to use getopt instead of manual string comparison
There is no error message when argument is a directory
Adding an output command
Hi, nice project :)
I would love to write a program that can output text, e.g. certain links, to stdout.
After a bit of research i got to the following asm snippet that works on Linux (Ubuntu 19.10) using the exact compile commands used in the program. It doesn't seem to work on Windows Subsystem for Linux though, there I get an Exec format error.
Anyways, here's the content of tmp.asm:
section .text
global main
main:
mov al, '!'
call writechar
ret
; Writes the ascii character in al to stdout
writechar:
push ebx
push ecx
push edx
push eax
mov edx, 1
mov ecx, esp
mov ebx, 1
mov eax, 4
int 128
pop eax
pop edx
pop ecx
pop ebx
retCompile & run:
nasm -f elf32 -o tmp.o tmp.asm
gcc tmp.o -g -o tmp -m32 -fno-pie -no-pie
./tmp
This outputs ! without any newlines etc, as expected. The same snippet also works in SASM.
I adapted the method from this site to get a version that works without any external dependencies, just some instructions.
Then I tried to add this to the translator.c file, but I can't seem to get it right. I changed very little (just entries in the commandPatterns and translationPatterns arrays), the file is here.
The string to insert in translationPatterns should probably be "push ebx\npush ecx\npush edx\npush eax\nmov edx, 1\nmov ecx, esp\nmov ebx, 1\nmov eax, 4\nint 128\npop eax\npop edx\npop ecx\npop ebx",.
When I tried my change with a file that just contains much wow (the command pattern for this, subject to change :D), it generates the following output in tmp.asm:
section .text
global main
main:
line_1:
push ebx
push ecx
push edx
push eax
mov edx, 1
mov ecx, esp
add
retThis doesn't compile and it's where I got stuck. It would be nice if you have any pointers on how to add the command. Thank you :)
The v-keyword should also support characters
New command idea: Banana / where banana
| Syntax | Usage |
|---|---|
| banana | sets a jump marker |
| where banana | jumps to that jump marker |
[Command suggestion] `it's free real estate [number/register]`
Command Syntax: (e.g. stonks [register])
it's free real estate [register/number]
Command Description:
Allocates the provided number of Bytes on the Heap and returns a pointer to the starting address. If the allocation failed, 0 is returned. The memory block cannot be freed - because who does that anyway? (hides)
Which x86_64 Assembly instruction(s) would be used to translate this command?
For a possible implementation, see https://github.com/xarantolus/memeasm/blob/main/malloc/malloc.memeasm
What could this command be useful for?
Well.. heap allocation
