On a 4-core Linux VM it has the following effect:
LESS_DEBUG_INFO=0
real 20m13.051s
user 63m45.648s
sys 6m51.636s
745.8 MB libvk_swiftshader.so
13 GB build dir
LESS_DEBUG_INFO=1
real 15m2.821s
user 51m8.659s
sys 5m17.466s
197.8 MB libvk_swiftshader.so
3.1 GB build dir
Also use /DEBUG:FASTLINK on Visual Studio. It disables producing a
single .pdb which can be relocated.
Specifying LESS_DEBUG_INFO=1 has no effect on Windows currently, but is
done for consistency and in case we start using Clang on Windows.
Also color errors in presubmit consistently.
