# In the PGO (Profile-Guided Optimization) build flow, we need to build the
# target binary multiple times. To implement this flow with gyp, here we
# define multiple 'executable' targets, each of which represents one build
# particular build/profile stage. On tricky part to do this is that these
# 'executable' targets should share the code itself so that profile data
# can be reused among these 'executable' files. In other words, the only
# differences among below 'executable' targets are:
# 1) PGO (Profile-Guided Optimization) database, and
# 2) linker options.
# The following static library contains all the logic including entry point.
# Basically we don't need to rebuild this target once we enter profiling
# phase of PGO.
