It's 2016 and COMPILERS ARE STILL STUPID

Just analysing a device driver for hardware few months old... as usual, it's as bloated as a week-old dead pig overall but then I come across pieces like this:

shl ecx, 4
mov edx, ecx
shr ecx, 2
xor eax, eax
rep stosd
mov ecx, edx
and ecx, 3
rep stosb

:facepalm:

Hi all, you might be pleased to know that I have found a solution to the problem of people with unwarranted levels of self importance, which manifests itself as seeing users with unironic and persistent names and tripcodes. As a solution to this problem, I have written a simple greasemonkey script to prevent us god-fearing /prog/-riders from having to experience the most visible and noticable parts of their pathological personality disorders, namely their use of the name and tripcode fields. I hope you all use it so these antisocial jerks will fail to recieve the attention they so desire and everyone else won't have to experience directed response at tripcode users. Please remember also to share this with anyone else who responds to tripcode users. Thank you!
