Manman Ren cd67bbf07f Add a parameter for getLazyBitcodeModule to lazily load Metadata. ... We only defer loading metadata inside ParseModule when ShouldLazyLoadMetadata is true and we have not loaded any Metadata block yet. This commit implements all-or-nothing loading of Metadata. If there is a request to load any metadata block, we will load all deferred metadata blocks. We make sure the deferred metadata blocks are loaded before we materialize any function or a module. The default value of the added parameter ShouldLazyLoadMetadata for getLazyBitcodeModule is false, so the default behavior stays the same. We only set the parameter to true when creating LTOModule in local contexts. These can only really be used for parsing symbols, so it's unnecessary to ever load the metadata blocks. If we are going to enable lazy-loading of Metadata for other usages of getLazyBitcodeModule, where deferred metadata blocks need to be loaded, we can expose BitcodeReader::materializeMetadata to Module, similar to Module::materialize. rdar://19804575 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@232198 91177308-0d34-0410-b5e6-96231b3b80d8		2015-03-13 19:24:30 +00:00
