[GCC] RISC-V: Add patterns for builtin overflow.
This patch has been committed to the master branch: https://gcc.gnu.org/pipermail/gcc-patches/2021-April/569135.html https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=6efd040c301b06fae51657c8370ad940c5c3d513 Learn more about Built-in Functions about Performing Arithmetic with Overflow Checking: https://gcc.gnu.org/onlinedocs/gcc/Integer-Overflow-Builtins.html Since these functions are pervasively used in the kernel, driver, etc. Adding patterns to the RISC-V backend should allow us to have some performance elevation. Some example: https://android.googlesource.com/kernel/common.git/+/refs/tags/ASB-2019-03-05_4.9/include/linux/overflow.h https://lwn.net/Articles/623368/ Let’s start with… Read more [GCC] RISC-V: Add patterns for builtin overflow.
[GCC] RISC-V: Avoid zero/sign extend for volatile loads.
This bug was initially raised by one of the developers on GCC Bugzilla https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97417 Where for a simple volatile load/store like: gcc will generate: However, the definition of lbu from RISC-V spec mentioned: ” The LW instruction loads a 32-bit value from memory and sign-extends this to 64 bits before storing it in register rd… Read more [GCC] RISC-V: Avoid zero/sign extend for volatile loads.
Momus — An image processing tool
Momus is a cross-platform image processing tool that designed to counter AI censorship on social media platforms. Momus是一款用来绕过社交平台AI图片匹配的跨平台工具 Github: https://github.com/LevyHsu/Momus Download exe release: https://github.com/LevyHsu/Momus/releases Online Demo: http://direct.momus.levyhsu.com/ Monus uses SIFT（Scale Invariant Feature Transform） from OpenCV to detect all keypoint on the image then inject noise to avoid auto-detection. Monus使用opencv库中的SIFT（Scale Invariant Feature Transform）算法来标记所有的关键点，然后添加噪音来避免社交平台的图片自动匹配。 Library: Install: run:… Read more Momus — An image processing tool
A simple implementation for using Zdns on a Web browser ( ZDNS is a command-line utility that provides high-speed DNS lookups. ) Github: https://github.com/LevyHsu/ZDNS-Flask Although authentication is implemented, it’s still recommended that you use this app on a local network instead of a public network. Also, use it at your own risk! Install Dependencies: sudo… Read more ZDNS-Flask

A process scheduling algorithms in C
Requirement: In the system, all the processes are grouped into six priority classes, ranged from 1 to 6, according to their membership status. A larger priority number indicates a higher priority. To maximize the system service performance, you are required to implement a scheduling algorithm using multi-level queue strategy with three queues: : a high… Read more A process scheduling algorithms in C
