There is a failing bot: http://45.33.8.238/macm1/40002/step_7.txt It looks to be failing because of a regex and how it handles whitespace, so modifying the CHECK line slightly to account for that.

First is the initialization and goto.
|
|
CHECK: store i32 5
|
|
CHECK-NEXT: br label %[[GOTO_TARGET:.+]]
|
|
|
|
Then comes the initialization of the for loop variable.
|
|
CHECK: store i32 0
|
|
CHECK-NEXT: br label %[[FOR_COND:.+]]
|
|
|
|
Then comes the for loop condition check label followed eventually by the
|
|
for loop body label.
|
|
CHECK: [[FOR_COND]]:
|
|
CHECK: {{.+}} = icmp slt i32 {{.+}}, 10
|
|
CHECK: [[FOR_BODY:.+]]:
|
|
CHECK: {{.+}} = icmp sgt i32 {{.+}}, 2
|
|
|
|
Then comes the then branch of the if statement.
|
|
CHECK: %[[I:.+]] = load i32,
|
|
CHECK-NEXT: %[[INC:.+]] = add nsw i32 %[[I]], 1
|
|
CHECK-NEXT: store i32 %[[INC]],
|
|
|
|
Eventually, we get to the goto label and its call
|
|
CHECK: [[GOTO_TARGET]]:
|
|
CHECK-NEXT: call void @foo()
|
|
CHECK-NEXT: br label %[[FOR_INC:.+]]
|
|
|
|
CHECK: [[FOR_INC]]:
|
|
CHECK-NEXT: %[[I2:.+]] = load i32,
|
|
CHECK-NEXT: %[[INC2:.+]] = add nsw i32 %[[I2]], 1
|
|
CHECK-NEXT: store i32 %[[INC2]],

CHECK-NEXT: br label %[[FOR_COND]]
