[PATCH] D40263: [TableGen] Improve error reporting

[Evandro Menezes via Phabricator via llvm-commits]

evandro added a comment.

Before this patch, a typical output would be like:

  .../llvm/lib/Target/AArch64/AArch64SchedA57.td:49:3: error: No ProcessorResources associated with A57UnitV
    def A57UnitV : ProcResGroup<[A57UnitX, A57UnitW]>;    // Type V micro-ops
    ^

Whereas after this patch, the offending line is output instead:

  .../llvm/lib/Target/AArch64/AArch64SchedM1.td:76:1: error: No ProcessorResources associated with A57UnitV
  def M1WriteA1 : SchedWriteRes<[A57UnitV]> { let Latency = 1; }
  ^

The latter is obviously clear what the issue is, unlike the former.
