[Interest] building Qt 5.9 on Linux - clang or GCC?

[René J.V. Bertin]

Hi,

Not to start a flame war, but are there clear differences between building Qt (on Linux) with clang (5.0) vs. GCC (7.2) that make the one or the other a better choice for certain domains of application?

Link-time optimisation is out of the question (too costly on my hardware, which is also why I can't really do a comparison). I'm not expecting much performance difference, so build time (cum memory requirements) and installation size can tip the scales for me.

Thanks!
