Switching the profile changes the settings for building gcc (it switches a = use- flag from forced-off to forced-on). A gcc-6 built with the 17.0 profiles wi= ll=20 produce PIE executables by default, a gcc-6 built with the 13.0 profiles wi= ll=20 not. I've added this paragraph: # Switching the profile modifies the settings of GCC 6 to generate # PIE executables by default; thus, you need to do the rebuilds # even if you already used GCC 6 beforehand. > The answer makes a big difference to those already on gcc-6.4+ and who > presumably already did an empty-tree rebuild of @world when upgrading to > it,=20 That's really not necessary anymore. =2D-=20 Andreas K.
