While profiling a clang invocation using `-ftime-trace`, now we add instant events when template instantiation is deferred. These events include the fully qualified name of the function template being deferred and therefore could be very verbose. This is therefore only added in verbose mode (when `TimeTraceVerbose` is enabled). The point of time when a particular instantiation is deferred can be used to identify the parent TimeTrace scope (usually another function instantiation), which is responsible for deferring this instantiation. This relationship can be used to attribute the cost of a deferred template instantiation to the function deferring this particular instantiation.
C language Family Front-end
Welcome to Clang.
This is a compiler front-end for the C family of languages (C, C++ and Objective-C) which is built as part of the LLVM compiler infrastructure project.
Unlike many other compiler frontends, Clang is useful for a number of things beyond just compiling code: we intend for Clang to be host to a number of different source-level tools. One example of this is the Clang Static Analyzer.
If you're interested in more (including how to build Clang) it is best to read the relevant websites. Here are some pointers:
