[utils][TableGen] Treat clause aliases equally with names
The code in DirectiveEmitter that generates clause parsers sorted
clause names to ensure that longer names were tried before shorter
ones, in cases where a shorter name may be a prefix of a longer one.
This matters in the strict Fortran source format, since whitespace
is ignored there.
This sorting did not take into account clause aliases, which are
just alternative names. These extra names were not protected in the
same way, and were just appended immediately after the primary name.
This patch generates a list of pairs Record+Name, where a given
record can appear multiple times with different names. Sort that
list and use it to generate parsers for each record.
What used to be
```
("fred" || "f") >> construct<SomeClause>{} ||
"foo" << construct<OtherClause>{}
```
is now
```
"fred" >> construct<SomeClause>{} ||
"foo" >> construct<OtherClause>{} ||
"f" >> construct<SomeClause>{}
```
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.
Consult the Getting Started with LLVM page for information on building and running LLVM.
For information on how to contribute to the LLVM project, please take a look at the Contributing to LLVM guide.

The LLVM project has adopted a code of conduct for participants to all modes of communication within the project.
