[llvm-dev] Is clang genned debuginfo really that huge

[via llvm-dev]

In a RelWithDebInfo (-g -O2) build of Clang, over 90% of the final executable size is DWARF information.
The percentage will be lower with a Debug build, but I don’t have an actual number for that.
You can look at the sizes of ELF sections whose names start with .debug_ to see for yourself.

Hi,
Slightly weekendy offtopic on debug info and stacktraces as afterthought on my fight with building clang on lowbie machine and how not to approach this area.

Slightly neg example: golang.

Sorry for offtop and have a nice weekend,
