I ran sv-benchmarks with our validation and this caused the confirmation rate to drop:
I don't exactly know why that is, but these fixed locations are definitely a correction for collaborating with other tools. These benchmarks were with Goblint self-validation, so it wasn't bothered at all by the invalid locations: it generated them and also validated them at the same (invalid) locations. |

This fixes the
c/weaver/chl-collitem-subst.wvr.cproblem in goblint/analyzer#1356.Because the logic of making locations synthetic is "Change all stmt and instr locs to synthetic, except the first one." and the
firstflag indicates whether the current statement is first, the logic should be flipped. That is, the first location should not be made synthetic.It's surprising that this complete logic flip didn't reveal itself from the very beginning of synthetic locations. This could be the reason we couldn't verify so many of our own witnesses even.
