Bug 193023 – [lldb-webkit] Remove broken code to print WTF::OptionSet::m_storage

• Component: Tools / Tests
• Status: RESOLVED FIXED

[Daniel Bates]

The WTF::OptionSet pretty printer contains code to print the value of WTF::OptionSet::m_storage. Due to an off-by-one error this code is broken and as a result we never print the value of WTF::OptionSet::m_storage when pretty printing the option set. Having said that, it does not seem very meaningful to print the value of m_storage as it is just the sum of the values of the enumerators in the set and I find it would just be noise if printed. We should just remove the code that tried to print WTF::OptionSet::m_storage.

If there is someone that likes knowing m_storage then we should still remove the current code and re-implement this functionality as part of the summary string for WTF::OptionSet so that we do not print m_storage as if it was an item in the set.

For completeness, if the code had worked then pretty printed output would look like:

(WTF::OptionSet<ExampleFlags>) $0 = { size = 3 } {
  A = 1
  C = 4
  D = 8
  m_storage = 13
}

Currently it looks like:

(WTF::OptionSet<ExampleFlags>) $0 = { size = 3 } {
  A = 1
  C = 4
  D = 8
}
