[#Compiler] Day 1 of #AoCO2025 Study Notes

While the original uses #CompilerExplorer, I wanted to replicate the analysis locally.

In this post, I have used #gcc, #clang, llvm-objdump and #LLDB to analyze.

Как я в 15 лет собрал LLVM ToolChain на Windows без MSVC

Как собрать актуальный LLVM со всеми рантаймами (Clang, LLD, LLDB, CLANG-EXTRA-TOOLS) нативно под Windows, если WinLibs перестал обновляться, а другие сборки не подходят? В этой статье я расскажу о своем 4-месячном пути: от накоплений со школьных обедов на первый ПК до борьбы с линковкой библиотек и поиска фиксов в экспериментальной ветке LLVM 22. История о том, почему я выбрал путь «чистого Upstream» и как заставил это всё работать в 15 лет. Заинтересовало

Bypassing iOS Frida Detection with LLDB and Frida

We (SCI Semiconductor) are about to hire some folks in the next couple of months (probably starting in January, since we're about to hit Christmas):

We're aiming to hire 1-3 FAEs, who can build out the open-source bits of the #CHERIoT software stack (including drivers / various communication stacks), build demos, and work with customers on use-case bringup.

We also want to hire someone else on the toolchain side. Primarily #LLDB + #OpenOCD, but also working with our #LLVM (and #RustC) folks.

Let me know if you're interested!

EDIT: We are a full-remote company. It's easiest for us to hire people in the UK (and one of our investors would really like us to hire more people in Sheffield), but elsewhere is possible (though might, for tax purposes, require you to be officially a contractor for a while).

We're also going to be hiring people for our hardware verification and RTL teams soon (more on the verification side than design at the moment, I think). I'm not responsible for them, but I can find out more details if anyone is interested. Our first CHERIoT chip is nearly finished, we're starting to work on the second.

EDIT 2: Thanks to all of the people who have expressed interest (in public and private posts). I'll try to get back to you all next week!

EDIT 3: I hope I've replied to everyone now! If I missed you (there were more replies than I expected!) please let me know. I think we'll aim to do another hiring round over the summer next year, so if the current timeline doesn't work out for you, please still let me know and I'll keep you in mind next time!

#GetFediHired

We released new Pwndbg: https://github.com/pwndbg/pwndbg/releases/tag/2025.05.30 !

Among others it brings:
- New & improved kernel debugging commands (buddydump, msr, slab) and more x64 regs in context
- New command for dealing with armcm exceptions: dump-register-frame
- Disasm now shows an ✘ marker for emulated branches we know won't be taken
- Improved disasm for ARM, MIPS and LoongArch64 architectures
- Initial support for the IBM s390x architecture
- IDA sync integration fixes

And also cool portable one-liner installers:
$ curl -qsL 'https://install.pwndbg.re' | sh -s -- -t pwndbg-gdb
$ curl -qsL 'https://install.pwndbg.re' | sh -s -- -t pwndbg-lldb
