Clang errors "expected register" with inline x86 assembly (works with GCC)

Asked 2021-Jun-16 at 00:48

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.

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.

I am having problems restarting the emulator after turning it off. Restarting android studio - doesn't help. Restarting my computer helps. I also cannot find and [stop this process] through the task manager. So that I can not reboot. By the way, the error is displayed with a typo. Help. Who faced such a problem, how to solve it?

On Windows, the software that runs the Android Emulator is called "qemu-system-x86_64.exe".

Try to kill this software. You can use the built-in taskkill utility from within the Command Prompt:

Open the Command Prompt (Type in CMD into the Windows search)
Enter: taskkill /F /IM "qemu-system-x86_64.exe" /T

QUESTION

Does this class satisfy the Allocator requirement?

Asked 2021-Jun-14 at 18:11

I made a custom allocator, but my code didn't compile on msvc and I'm not sure if my implementation satisfies the Allocator requirement (disregarding actual behavior of function implementations here). Here is a minimal example that reproduces the error on Visual Studio (16.11 P1 and 16.10):

...

ANSWER

Answered 2021-Jun-14 at 18:11

It does not.

An allocator rebound to a different value type must be constructible from the original allocator - this is the A a(b) row in the requirements you linked.

Your type fails that requirement.

While 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.

Assistance needed scraping a site with Selenium in Python

I am trying to scrape the NBA player names and projected fantasy score (not single stat DFS) using selenium. I've gotten as far as using selenium to automate clicking NBA, and selecting the fantasy score tab.

From there, I see the players in a grid where I will like to scrape the points and names for each player. I have attempted to loop through the grid but I don't think I'm doing it right

Can someone please take a look at my code and point me in the right direction ?

Web Scraping ESPN Data With Selenium

Asked 2021-Jun-13 at 16:15

I'm trying to scrape some data off ESPN and run some calculations off the scraped data. Ideally, I will like to iterate through a dataframe, grab the players name with Selenium, send the player's name into the search box and tell Selenium to click the player's name. I was able to do this successfully with one player. I'm not quite sure how to iterate through all the players in my data frame.

The second part of the code is where I'm struggling. For some reason I am not able to get the data. Selenium isn't able to find any of the elements. I don't think I'm doing it properly. If I am able to scrape the required data, I will like to plug them into a calculation and append the calculated projected points into my dataframe, dfNBA.

Can someone please help me with my code? and point me in the right direction. I'm trying to be more efficient writing python codes but right now I'm stuck

Thanks

Here's some code to accomplish (I think) what you want. You need to wait for the table elements to appear, fix your xpath, and choose the right elements from the table array.

There is no need to use the Marshal.GetActiveObject method to get the running instance of Outlook twice. Typically, it is used when you want to get the already running instance, not started by your code. But even if you create a new Application instance for automating it you get the same results because Outlook is a singleton - you can't start two instances simultaneously.

Instead of using the sleep statement in the code I'd suggest handling the MAPILogonComplete event of the Application class which is fired after the user has logged onto the system. So, in the event handler you may get all the required information.
