This patch is to address https://bugs.llvm.org/show_bug.cgi?id=50459. YAML:455:28: error: GUID strings are 38 characters long The valid format for a GUID is {XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX} where X is a hex digit (0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F). The length of the individual components must be: 8, 4, 4, 4, 12. For some cases, the converted string generated by obj2yaml, does not comply with those lengths. yaml2obj checks that the GUID string must be 38 characters including the dashes and braces.

// Variant 2 UUIDs, historically used in Microsoft's COM/OLE libraries, use a

// mixed-endian format, whereby the first three components of the UUID are

// little-endian, and the last two are big-endian.

// For example, 00112233-4455-6677-8899-aabbccddeeff is encoded as the bytes
