-; This test is attempting to detect that the compiler correctly generates stack
-; probe calls when the size of the local variables exceeds the specified stack
-; probe size.
-;
-; Testing the default value of 4096 bytes makes sense, because the default
-; stack probe size equals the page size (4096 bytes for all x86 targets), and
-; this is unlikely to change in the future.
