As a common language extension, this compiler accepts a structure constructor whose first value has no keyword and whose type matches an ancestral type as if the constructor had had a keyword whose name was the ancestral type. For example, given TYPE PARENT; REAL X; END TYPE TYPE, EXTENDS(PARENT) :: CHILD; END TYPE we accept the nonconforming constructor "child(parent(1.))" as if it had been the conforming "child(1.)" or "child(parent=parent(1.))". The detection of this case needs to be constrained a bit to avoid a false positive misinterpretation of conforming code in the case where the actual first component of the derived type is a POINTER or ALLOCATABLE whose type and rank would allow it to correspond with the keywordless first value in the component value list.

The LLVM Compiler Infrastructure
Welcome to the LLVM project!
This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.
The LLVM project has multiple components. The core of the project is itself called "LLVM". This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.
C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.
Other components include: the libc++ C++ standard library, the LLD linker, and more.
