Expand description
This enum represents the kind of directive that was parsed
Variants§
None
Not used after parsing, represents a line with no directives
Plain
The base CHECK directive, i.e. match the pattern is somewhere in the file
Next
The CHECK-NEXT directive, i.e. the pattern must match on the next line from the previous pattern.
Same
The CHECK-SAME directive, i.e. the pattern must match on the same line as the previous pattern.
Not
The CHECK-NOT directive, i.e. the pattern must not match between this directive and the next positive match directive, or the end of file. This is the only negative match assertion supported.
Dag
The CHECK-DAG directive, i.e. like CHECK, but may match in any order relative to other CHECK-DAG directives which are all part of a single consecutive grouping. A non-CHECK-DAG directive between two sets of CHECK-DAG directives cause the two sets to be split into two logical groups, where the ordering between the groups is strict, but within the group it is not.
Label
The CHECK-LABEL directive, i.e. a regular CHECK, with the additional restriction that the pattern may not contain references to (or bind) variables. This directive type divides the checks (and input) into logical “blocks”. Checks other than CHECK-LABEL belong to the block defined by their preceding CHECK-LABEL. Checks before the first CHECK-LABEL are part of an implicit prologue block.
CHECK-LABEL divides up the input into blocks as well, by first matching all of the CHECK-LABEL patterns, and then block-by-block, matching all of the checks “owned” by each CHECK-LABEL, rejecting any matches that would match outside the region of input assigned to the block.
Empty
The CHECK-EMPTY directive, i.e. the next line must be empty, containing nothing but a newline, no other whitespace.
Count(usize)
This is only used during parsing, but represents CHECK-COUNT-N, i.e. a CHECK that is repeated N times. N must be non-zero.
Comment
The COM directive, i.e. a comment.
This is only used during parsing.
