Search filters

Filter	Description	Example
allintext	Searches for occurrences of all the keywords given.	`allintext:"keyword"`
intext	Searches for the occurrences of keywords all at once or one at a time.	`intext:"keyword"`
inurl	Searches for a URL matching one of the keywords.	`inurl:"keyword"`
allinurl	Searches for a URL matching all the keywords in the query.	`allinurl:"keyword"`
intitle	Searches for occurrences of keywords in title all or one.	`intitle:"keyword"`

This downloads standalone MSVC compiler, linker & other tools, also headers/libraries from Windows SDK into portable folder, without installing Visual Studio. Has bare minimum components - no UWP/Store/WindowsRT stuff, just files & tools for native desktop app development.

Run py.exe portable-msvc.py and it will download output into msvc folder. By default it will download latest available MSVC & Windows SDK - currently v14.40.33807 and v10.0.26100.0.

You can list available versions with py.exe portable-msvc.py --show-versions and then pass versions you want with --msvc-version and --sdk-version arguments.

To use cl.exe/link.exe first run setup_TARGET.bat - after that PATH/INCLUDE/LIB env variables will be updated to use all the tools as usual. You can also use clang-cl.exe with these includes & libraries.

To use clang-cl.exe without running setup.bat, pass extra /winsysroot msvc argument (msvc is folder name where output is stored).

Unconditional Branch/Jump to Itself

In reverse engineering we often need an executable binary to mapped in memory, stopped at a certain address. One approach is to modify the executable binary temporarily to jump at its own address. I have written a very small c code and compile it with optimization level 2.

This is a gist used in the following blog posts:

	You are an expert-level reverse engineering assistant, an advanced LLM with comprehensive mastery of low-level systems programming, binary analysis, compiler internals, and modern C++ (C++11-C++23). Your primary task is the meticulous reconstruction of high-level, modern C++ source code from low-level representations like pseudo-C or assembly, with extreme technical precision and architectural insight.

	Your analysis must be informed by a deep understanding of how modern C++ features are compiled into machine code. You will operate in a step-by-step process:
	1. Analyze: Deeply examine the input low-level code to identify architectural patterns, data structures, and control flow.
	2. Reason: Internally map these low-level patterns to their original high-level, idiomatic C++ constructs using the detailed guidelines below.
	3. Reconstruct: Output a high-level C++ code representation that is as faithful as possible to the original logic, incorporating modern C++ best practices for clarity, safety, an
