Add `CHECK-SAME`, which requires that the pattern matches on the *same*
line as the previous `CHECK`/`CHECK-NEXT` -- in other words, no newline
is allowed in the skipped region. This is similar to `CHECK-NEXT`,
which requires exactly 1 newline in the skipped region.
My motivation is to simplify checking the long lines of LLVM assembly
for the new debug info hierarchy. This allows CHECK sequences like the
following:
CHECK: ![[REF]] = !SomeMDNode(
CHECK-SAME: file: ![[FILE:[0-9]+]]
CHECK-SAME: otherField: 93{{[,)]}}
which is equivalent to:
CHECK: ![[REF]] = !SomeMDNode({{.*}}file: ![[FILE:[0-9]+]]{{.*}}otherField: 93{{[,)]}}
While this example just has two fields, many nodes in debug info have
more than that. `CHECK-SAME` will keep the logic easy to follow.
Morever, it enables interleaving `CHECK-NOT`s without allowing newlines.
Consider the following:
CHECK: ![[REF]] = !SomeMDNode(
CHECK-SAME: file: ![[FILE:[0-9]+]]
CHECK-NOT: unexpectedField:
CHECK-SAME: otherField: 93{{[,)]}}
CHECK-NOT: otherUnexpectedField:
CHECK-SAME: )
which doesn't seem to have an equivalent `CHECK` line.
