It looks like this pull request may not have tests. Please make sure to add tests or get an explicit test exemption before merging. If you are not sure if you need tests, consider this rule of thumb: the purpose of a test is to make sure someone doesn't accidentally revert the fix. Ask yourself, is there anything in your PR that you feel it is important we not accidentally revert back to how it was before your fix? Reviewers: Read the Tree Hygiene page and make sure this patch meets those guidelines before LGTMing. If you believe this PR qualifies for a test exemption, contact "@test-exemption-reviewer" in the #hackers channel in Discord (don't just cc them here, they won't see it!). The test exemption team is a small volunteer group, so all reviewers should feel empowered to ask for tests, without delegating that responsibility entirely to the test exemption group. |

Code Review
The pull request successfully adds stacktrace support for host builds as intended. The change correctly integrates the is_host_build function into the backtrace enablement logic, ensuring that host builds benefit from this feature. The pre-launch checklist is also fully completed.
| if args.backtrace: | ||
| gn_args['enable_backtrace'] = ( | ||
| args.target_os in ['linux', 'mac', 'win'] or | ||
| is_host_build(args) or args.target_os in ['linux', 'mac', 'win'] or |

The condition for enable_backtrace contains some redundancy. The is_host_build(args) function already covers args.target_os == 'mac' and args.target_os == 'linux' and args.linux_cpu == 'arm64'. Therefore, explicitly including 'mac' and 'linux' in the args.target_os in ['linux', 'mac', 'win'] list creates redundant checks.
To improve readability and conciseness, consider simplifying the condition by removing the redundant checks for 'mac' and 'linux' from the list, as they are already covered by is_host_build(args) or the explicit args.target_os == 'linux' check.
This aligns with the repository's philosophy to "Optimize for readability" and "Write what you need and no more, but when you write it, do it right." (Repository Style Guide, lines 29, 31).

This check is not redundant as for host builds, args.target_os is None.
