[cfe-dev] Proposal: Enable BUILD_SHARED_LIBS=ON by default for debug build.

[Yin Ma via cfe-dev]

Hello, 

 

I understand shared linked is currently a lot slower than static linked.

However, for debug build, where speed is not required. Shared link has 

A lot of advantage. 

 

Static linked clang/llvm on linux is 17G, shared build is only 1.5G. On a
mainstream 

linux host machine with 12G memory, only -j1 can be used to finish final
linking step. 

With -j8 the linux will link the linking. With 17G footprint, copying from
build folder

to install folder is also very slow. So it is very reasonable to set 

BUILD_SHARED_LIBS=ON as default for debug build because it would improve
usability

and performance. 

 

Thanks,

 

Yin
