New Revision: 334585
URL: http://llvm.org/viewvc/llvm-project?rev=334585&view=rev
Log:
[clangd] Move caching of compile args out of ClangdServer.
Summary:
Caching is now handled by ClangdLSPServer and hidden behind the
GlobalCompilationDatabase interface. This simplifies ClangdServer.
This change also removes the SkipCache flag from addDocument,
which is now obsolete.
No behavioral changes are intended, the clangd binary still caches the
compile commands on the first read.
