This moves the following classes from Core -> Utility. ConstString Error RegularExpression Stream StreamString The goal here is to get lldbUtility into a state where it has no dependendencies except on itself and LLVM, so it can be the starting point at which to start untangling LLDB's dependencies. These are all low level and very widely used classes, and previously lldbUtility had dependencies up to lldbCore in order to use these classes. So moving then down to lldbUtility makes sense from both the short term and long term perspective in solving this problem. Differential Revision: https://reviews.llvm.org/D29427 llvm-svn: 293941

|
///
|
|
/// Caches locally modules that are downloaded from remote targets.
|
|
/// Each cached module maintains 2 views:
|
|
/// - UUID view:
|
|
/// /${CACHE_ROOT}/${PLATFORM_NAME}/.cache/${UUID}/${MODULE_FILENAME}
|
|
/// - Sysroot view:
|
|
/// /${CACHE_ROOT}/${PLATFORM_NAME}/${HOSTNAME}/${MODULE_FULL_FILEPATH}

///
|
|
/// UUID views stores a real module file, whereas Sysroot view holds a symbolic
|
|
/// link to UUID-view file.
|

/// Example:
|
|
/// UUID view :

|
/// /tmp/lldb/remote-linux/.cache/30C94DC6-6A1F-E951-80C3-D68D2B89E576-D5AE213C/libc.so.6
