Never heard of that ;) In my understanding 'common' and 'local' exclude themselves, locals should go to .bss (possibly .lcomm is a thing on targets w/o .bss?). > What I am trying to achieve is to implement a variable attribute, and to get > some noswitch section attached to a VAR_DECL in static storage. > > Since common static variables are not in lcomm_section, the attribute fails > for > local variables. > > FYI, regarding the variable attribute, what also doesn't work is to return a > custom noswitch section in TARGET_ASM_SELECT_SECTION since that hook is not > called for all static storage VAR_DECLs.
