QUESTION
I wrote a demo with some inline assembly (showing how to shift an array of memory right one bit) and it compiles and functions fine in GCC. However, the with Clang, I'm not sure if it's generating bad code or what but it's unhappy that I'm using memory despite the "rm" constraint.
I've tried many compilers and versions via Godbolt and while it works on all x86/x86_64 versions of GCC, it fails with all versions of Clang. I'm unsure if the problem is my code or if I found a compiler bug.

The problem is your code. In GNU assembler, parentheses are used to dereference like unary * is in C, and you can only dereference a register, not memory. As such, writing 12(%0) in the assembly when %0 might be memory is wrong. It only happens to work in GCC because GCC chooses to use a register for "rm" there, while Clang chooses to use memory. You should use "r" (bytes) instead.
Also, you need to tell the compiler that your assembly is going to modify the array, either with a memory clobber or by adding *(unsigned char (*)[16])bytes as an output. Right now, it's allowed to optimize your printf to just hardcode what the values were at the beginning of the program.

QUESTION
I have a pair of iterator, and I would like to use ranges::views::filter(some_predicate) on it (with the pipe operator). AFAIU I should first convert my pair of iterator into a view. I tried to use ranges::subrange(first, last) to do so, but I’m getting horrible error messages.
Note1: I’m using C++14 and range-v3 version 0.9.1 (the last version compatible with gcc-5.5). If the solution differs when using C++17/20 and/or when using C++20 std::ranges, I’m also interested to know what changed.
Note2: I find the documentation of range-v3 severely lacking, so I’m using cppreference.com. If you know a better documentation, I’m very interested.
EDIT:
In my real code, I’m wrapping a java-style legacy iterator (that has a next() method instead of operator++/operator*. I’m wrapping them in a C++-compatible wrapper. Then I tried to convert that wrapper into a view, and finally filter it. I reproduce a minimal example on godbolt. This use iterator_range as suggested, but it still doesn’t compile (see the second edit below).
ANSWER
Answered 2021-Apr-08 at 16:24In ranges-v3, there is iterator_range which you can use to wrap the iterators into a range object.
In C++20, you can use std::span to wrap those iterators into an range object

I have problem with my bpf program. I getting error while loading this program. my bpf program is:
...ANSWER
Answered 2021-Jun-15 at 07:28TL;DR. You should check that the pointer returned by bpf_map_lookup_elem is not NULL.
With the following logs, the BPF verifier is telling you that, when it reaches the dereference of my_pid, the pointer may still have a NULL value. It thus contains a map value or a NULL value, i.e., map_value_or_null.
QUESTION
I would like to learn some inline assembly programming, but my first cod snippet does not work. I have a string and I would like to assign the value of the string to the rsi register.
Here is my code:
...ANSWER
Answered 2021-Jun-14 at 16:42You left out a : to delimit the empty outputs section. So "S"(ystr) is an input operand in the outputs section, and "%rsi" is in the inputs section, not clobbers.
But as an input it's missing the (var_name) part of the "constraint"(var_name) syntax. So that's a syntax error, as well as a semantic error. That's the immediate source of the error :9:5: error: expected '(' before ')' token. https://godbolt.org/z/97aTdjE8K
As Nate pointed out, you have several other errors, like trying to force the input to pick RSI with "S".

40in hex is0x28
therefore your result is0x28or28h
QUESTION
I'm trying to extract method parameters information from Java class bytecode using asm MethodVisitor. visitParameter method of MethodVisitor is not called (because no parameter names are present in compiled class file). How can i get count of method parameters and their types?
The only thing I've found so far is desc parameter of visitMethod from MethodVisitor. I can copy-paste TraceSignatureVisitor class from asm-util, rewrite about 50 lines of code to store parameters declarations into List/array instead of single StringBuffer.
Another option is suggested by in answer "https://stackoverflow.com/questions/18061588/get-function-arguments-values-using-java-asm-for-bytecode-instrimentation":
The number of arguments to the method can be computed from the method description using the code in the following gist: https://gist.github.com/VijayKrishna/6160036. Using the
parseMethodArguments(String desc)method you can easily compute the number of arguments to the method.
From my point of view copy-pasting and rewriting TraceSignatureVisitor is still better.
But i suppose there should be more simple way to work with method signatures in asm-util. Is there?
...ANSWER
Answered 2021-Jun-14 at 07:55ASM has an abstract for that purpose, Type.
Instances of Type may represent a primitive type, a reference type, or a method type. So you can first get a type to represent the method type from the descriptor string, followed by querying it for the parameter types and return type.
QUESTION
I am creating my first x86 assembly program. I am using VS Code as my editor and using Insight as my debugger coupled with DOSBox as my emulator.
As a start I have created a .asm program to change to colour of the screen:
ANSWER
Answered 2021-Jun-14 at 05:29While DOSBox emulates a 32-bit CPU, DOS itself runs in 16-bit real mode, without tools like DOS4gw, used in some DOS Games, such as Doom.
I think the -f win32 command line option is to blame for this error.
QUESTION
I need to write inline assembly code in C in format like this:
...ANSWER
Answered 2021-Jun-14 at 05:09In general, when using gcc inline asm on x86, you NEVER want to include mov instructions, or explicit registers in the asm code. Instead, you want to use the constraints to force inputs and output into specific registers. The constraints available are:
QUESTION
uint32_t sum_a_b(uint32_t a, uint32_t b) {
return a + b;
}
uint32_t mul_c_d(uint32_t c, uint32_t d) {
return c * d;
}
int main(uint16_t argc, char **argv) {
uint32_t e;
e = mul_c_d(116, sum_a_b(17, 992));
return 0;
}
ANSWER
Answered 2021-Jun-01 at 10:01The C standard doesn't specify where variables and values are stored, so the results will be very system-specific.
"Some "temporary variable" at stack?" Likely.
"Processor registers?" Likely.
"Heap?" No. The heap is only used when there's an explicit call to malloc or equivalent function. No known C compiler utilizes the heap implicitly.
Unfortunately I don't have enough asm / disasm skills to check it directly
You don't need to know a lot of assembler to do that. Just toss your code into https://godbolt.org/, disable optimizations, and this is what you get (x86):

Install ASM
You can use ASM like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
