[GitHub] [incubator-doris] adonis0147 opened a new issue, #9676: [Enhancement] Improve debugging experience.
adonis0147 opened a new issue, #9676:
URL: https://github.com/apache/incubator-doris/issues/9676
### Search before asking
- [X] I had searched in the [issues](https://github.com/apache/incubator-doris/issues?q=is%3Aissue) and found no similar issues.
### Description
This issue proposes two changes to improve debugging experience.
1. Use `lld` to speed the link time of `doris_be_test` up.
2. Explicitly set the version of `dwarf` to use debug info in `dwarf-5` format which is the latest and has numerous minor additions to improve functionality and performance.
Foregoings are _**NOT**_ mandatory.
**REMARK**
GCC 11.0+ produces DWARF debugging information in `dwarf-5` by default if it was built against binutils version 2.35.2 or higher according to [GCC 11 Release Note](https://gcc.gnu.org/gcc-11/changes.html). GCC 11.1 in [ldb toolchain](https://github.com/amosbird/ldb_toolchain_gen) may be built against binutils with earlier version, hence, it doesn't produces the debugging information in version 5.
### Solution
1. Use `lld` to speed the link time of `doris_be_test` up.
2. Explicitly set the version of `dwarf` to use debug info in `dwarf-5`.
