What do you think? I'm not sure we want to create a the replacement decl with DECL_SIZE zero though, so I suppose instead of making sure align is BITS_PER_UNIT shouldn't we make sure that size is at least 1? I fear we might run into other odd problems with zero-size autos. Thus, a variant of the patch that re-enables handling of size zero allocas but adjusts the size to be at least 1 is ok. Other opinions? Thanks, Richard. > -- > Eric Botcazou >
