[Development] clangbackend qtcreator 4.2 memory hogging

[Marco Bubke]

If c++ modules becomes supported it could go down but actually you should request that in the clang mailling list. We open a translation unit for every file and they are that big. We research precompiled header to improve speed and maybe they provide advantages in memory usage too.

Subject: [Development] clangbackend qtcreator 4.2 memory hogging

I have small project in which contains 2k SLOC with heavy v8 js
template included in source file.
For small opening 3-4 sources file this take almost 870mb in memory
with no precompiled header being checked plus qtcreator eats 280mb
with 2gb Intel celeron and this is definitely not desirable for me. I
have feature request  whether is this possible to put heavy c++ symbol
data in sqlite file with multithread concurrent access mechanism
instead to keep clangbackend memory usage being low?
