I would like to know where does the so-called 'gather' exactly happens?
For example, does it mean the bitbake core get the 'PN = u-boot' by
cutting of the name of 'u-boot_2011.03.bb'?

If you want to know exactly where it happens, see bitbake.conf:

PN = "${@bb.parse.BBHandler.vars_from_file(d.getVar('FILE'),d)[0] or
'defaultpkgname'}"
PV = "${@bb.parse.BBHandler.vars_from_file(d.getVar('FILE'),d)[1] or '1.0'}"
PR = "${@bb.parse.BBHandler.vars_from_file(d.getVar('FILE'),d)[2] or 'r0'}"
