--- Comment #15 from Robin Dapp <rdapp at gcc dot gnu.org> --- > Based on earlier builds this file will take 2.5 to 3 hours to build (while > all other cores are idle). insn-attrtab.c doesn't consist of many functions so a split won't help. Given that we have a number of huge if/else constructs in it I could imagine the ifcombine change being a culprit.
