Built a niche site on compilers (compilersutra.com)
Last 12 months:
→ 1.09M impressions
→ 11K clicks
Ranking for LLVM, OpenCL, TVM.
Just consistent deep-tech content.
Still early. Long way to go

Most devs write code.
Few know how it becomes machine instructions.
Building VELOX:
Frontend → LLVM IR → opt → llc → RISC-V → QEMU
👉 pulse = unit of computation

Just published a hands-on guide to building your own LLVM Pass as a plugin!
Learn how to:
✅ Create a custom pass
Perfect for anyone diving into compiler internals 🔥

Compiler MCQs for Engineers & Students 🚀
Test your fundamentals (IR, passes, backend).
Concept-based, interview-focused.

Everyone talks about AI models.
No one talks about how they actually run.
That’s where compilers come in.

6 lines of Triton → thousands of GPU instructions.
Python → TTIR → TTGIR → LLVM → AMDGCN → HSACO
a b → buffer_load_b128
mask → v_cmp
Your code ≠ what GPU runs.

Just launched CompilerSutra on Vercel
Working on a resource for:
Compilers (LLVM, IR, optimization)
ML Compilers (MLIR, TVM, GPU kernels)
📊 Early traffic already coming in from Google users reading docs
Check it out:

Sharing a short write-up on measuring CPU behavior using perf.
Covers:
cycles, instructions, IPC
cache misses and their impact
sequential vs random access
Practical way to debug why a C loop is slow.

Most compiler content is too theoretical.
I’m building CompilerSutra to fix that — practical deep dives on LLVM, MLIR, and performance ⚙️

Because it’s not just codegen it’s backend execution strategy.
In my benchmark
👉 GCC is ~25% faster than Clang
👉 Due to better AGU utilization instruction scheduling
👉 Lower pipeline stalls in hot loops
Same instructions ≠ same performance.
#gcc #clang #llvm #Compilers

Most people think:
👉 Performance = fewer instructions
❌ Wrong
Same code. Same instructions.
Still GCC is ~25% faster than Clang
Why? 👇
Comment down the reason we will discuss tommorow

#CPU doesn’t run code.
It runs #bytes.
#Fetch → #Decode → #Execute → #Writeback
#Perf ≠ #instructions
It’s:
• #cache
• #deps
• #pipeline
#RAM miss = 💀 (200 cycles)
👉 #CPU fast. #Memory is slow.

Most people think performance = instruction count.
Not true.
Same instructions.
Same code.
GCC is ~25% faster than Clang here.
Reason?
AGU pressure scheduling.
Compilers don’t just generate code
they decide how the CPU gets fed.
