Hi,
I would like to improve the build speed of a large project. The opt
build is compiled with -O2 -g. I noticed that without -g, compilation
becomes faster, about 10-20%. The resulting binary has enough
information to analyze crashes, except for the line numbers. Is there a
way to include line number information but nothing else?
According to [1], line numbers are produced only at level 2 (i.e. -g2
or the default of -g) or above. But according to [2], line numbers are
only a fraction of the debug information (1%). So for me it would be
best to have -g0 or -g1 but with line numbers. Is this possible?
