peter klausler a39e9cf6be [flang] Basic tests of external I/O runtime (part 9/9)
Add new unit tests for external Fortran I/O that drive the
Fortran I/O runtime API from C++ and exercise basic writing
and read-back in the various combinations of access modes,
record length variability, and formatting.  Sequential modes
are tested with positioning.  More thorough tests written in
Fortran will follow when they can be compiled and run.

The Fortran runtime's error termination callback registration
was extended with source file and line number positions for
better failure messages in unit testing.

Isuru Fernando 3862cbbc65 [flang] Use LLVM's flags
Summary:
The only difference is that LLVM_ENABLE_WERROR is set to OFF
by default, but we enable this in a standalone flang build

This commit fixes some windows issues with the flags

peter klausler fc0262419a [flang] More CHARACTER runtime support + unit test
Summary:
This is a continuation of development of the runtime support library's functions for
CHARACTER data; specifically, it implements CHARACTER comparisons.
It includes a new unit test, and moves an #include directive to the
runtime's unit testing main header.

Patrick McCormick 6c16aa4f67 [flang] A rework of the cmake build components for in and out of tree builds.
In general all the basic functionality seems to work and removes some redundancy
and more complicated features in favor of borrowing infrastructure from LLVM
build configurations. Here's a quick summary of details and remaining issues:

  * Testing has spanned Ubuntu 18.04 & 19.10, CentOS 7, RHEL 8, and
    MacOS/darwin.  Architectures include x86_64 and Arm.  Without
    access to Window nothing has been tested there yet.

  * As we change file and directory naming schemes (i.e.,
    capitalization) some odd things can occur on MacOS systems with
    case preserving but not case senstive file system configurations.
    Can be painful and certainly something to watch out for as any
    any such changes continue.

  * Testing infrastructure still needs to be tuned up and worked on.
    Note that there do appear to be cases of some tests hanging (on
    MacOS in particular).  They appear unrelated to the build
    process.

  * Shared library configurations need testing (and probably fixing).

  * Tested both standalone and 'in-mono repo' builds.  Changes for
    supporting the mono repo builds will require LLVM-level changes that
    are straightforward when the time comes.

  * The configuration contains a work-around for LLVM's C++ standard mode
    passing down into Flang/F18 builds (i.e., LLVM CMake configuration would
    force a -std=c++11 flag to show up in command line arguments.  The
    current configuration removes that automatically and is more strict in
    following new CMake guidelines for enforcing C++17 mode across all the
    CMake files.

  * Cleaned up a lot of repetition in the command line arguments.  It
    is likely that more work is still needed to both allow for
    customization and working around CMake defailts (or those
    inherited from LLVM's configuration files). On some platforms agressive
    optimization flags (e.g. -O3) can actually break builds due to the inlining
    of templates in .cpp source files that then no longer are available for use
    cases outside those source files (shows up as link errors).   Sticking at -O2
    appears to fix this.  Currently this CMake configuration forces this in
    release mode but at the cost of stomping on any CMake, or user customized,
    settings for the release flags.

  * Made the lit tests non-source directory dependent where appropriate. This is
    done by configuring certain test shell files to refer to the correct paths
    whether an in or out of tree build is being performed. These configured
    files are output in the build directory. A %B substitution is introduced in
    lit to refer to the build directory, mirroring the %S substitution for the
    source directory, so that the tests can refer to the configured shell scripts.

Caroline Concatto 8670e49901 [flang] [LLVMify F18] Replace the use std::ostream with LLVM streams llvm::ostream
This patch replaces the occurrence of std::ostream by llvm::raw_ostream.
In  LLVM Coding Standards[1] "All new code should use raw_ostream
instead of ostream".[1]

As a consequence, this patch also replaces the use of:
   std::stringstream by llvm::raw_string_ostream or llvm::raw_ostream*
   std::ofstream by llvm::raw_fd_ostream
   std::endl by '\n' and flush()[2]
   std::cout by llvm::outs()   and
   std::cerr by llvm::errs()

It also replaces  std::strerro by llvm::sys::StrError** , but NOT in  Fortran
runtime libraries

*std::stringstream were replaced by llvm::raw_ostream in all methods that
used std::stringstream as a parameter. Moreover, it removes the pointers to
these streams.

Luke Ireland ee5fa1f233 [flang] Create a separate directory for unittests
Some of the regression tests are C programs that act as test harnesses
for the compiler internals as opposed to being Fortran inputs to test
the compiler in action. The former style of tests are analog to LLVM's
unittests and will not use the lit framework.
