LeetCode Assembly: 14,112 Compilations Across 4 Architectures

14,112 records of C-to-assembly compilations covering 441 LeetCode problems across four architectures and two compilers. Created by ronantakizawa and updated in February 2026, the collection utilizes the Godbolt Compiler Explorer API to generate assembly code at four optimization levels. Each problem solution is paired with its corresponding assembly output, achieving a 100% compilation success rate.

Use Cases

• Decompilation research using the assembly code and original C source columns
• Compiler optimization analysis by comparing -O0 and -O3 outputs for the same problem
• Cross-architecture translation between x86-64 and RISC-V 64 assembly versions of the same logic

Strengths

• 14,112 total rows of paired source and assembly code
• 100% compilation success rate across all included problems
• Coverage of 4 distinct architectures including RISC-V 64 and MIPS64
• Includes 4 optimization levels from -O0 to -O3

Limitations

• Small sample of 441 unique problems may limit algorithmic diversity
• Restricted to C source code only
• Potential bias toward 'Easy' difficulty problems
