[cfe-dev] Clang: How to Analyse Compiletime of Templates?

[Alexandre Ganea via cfe-dev]

Hi Dennis,

Along with -ftime-trace, try either:
- Clang Build Analyzer: https://aras-p.info/blog/2019/09/28/Clang-Build-Analyzer/
- See++ Compiler Profiler: https://github.com/Viladoman/SeeProfiler

Objet : [cfe-dev] Clang: How to Analyse Compiletime of Templates?

hello clang-devs,

is clang able to help me to finde the most compiletime consuming templates in a 500KLOC app which uses a huge template library - something like a overview what templates are reasonable to optimize (in my case hide the template behind a specialized interface)

i've read about /ftime

https://aras-p.info/blog/2019/01/16/time-trace-timeline-flame-chart-profiler-for-Clang/

but that seems no to help with template instanciation

any advice?
