Notes

• This repository uses an AI bot for reviews. Keep your PR in Draft while
  you work. When you’re ready for a review, change the status to Ready for
  review to trigger a new review round. If you make additional changes and
  don’t want to trigger the bot, switch the PR back to Draft.
• AI-bot comments may not always be accurate. Please review them critically and
  share your feedback; it helps us improve the tool.
• Avoid changing code that is unrelated to your proposal. Keep your PR as short
  as possible to increase the chances of a timely review. Large PRs may not be
  reviewed and may be closed.
• Don’t add unnecessary comments. Your code should be readable and
  self-documenting
  (guidance).
• Don’t change core features without prior discussion with the community. Use
  our Discord to discuss ideas, blockers, or issues
  (https://discord.gg/Nu4MdGj9jB).
• Do not include secrets (API keys, tokens, passwords), credentials, or
  sensitive data/PII in code, configs, logs, screenshots, or commit history. If
  something leaks, rotate the credentials immediately, invalidate the old key,
  and note it in the PR so maintainers can assist.
• Do not commit large binaries or generated artifacts. If large datasets are
  needed for tests, prefer small fixtures or programmatic downloads declared in
  makim.yaml (e.g., a task that fetches data at test time). If a large binary is
  unavoidable, discuss first and consider Git LFS.

hi @yuvimittal ,
i have made PR related to set :-

Summary of what was done:

• Extended LiteralSet lowering to support homogeneous float constant sets
• Improved mixed-width integer handling with proper type promotion
• Added runtime lowering for non-constant integer sets using alloca + store
• Fixed unsafe builder context access by using builder.block instead of builder.function

Added tests covering:

• Added tests for float support and runtime lowering
• Ensured all tests pass and follow project conventions

@yuvimittal , can you please review this PR.

here also check output as well

[yuvimittal]

@m-akhil-reddy , are you facing while making the test? few contributors are facing some issues while asserting the output?

[m-akhil-reddy]

@yuvimittal , Updated tests to validate output values in a format-independent way and verified runtime lowering through emitted IR instructions.
