[NOTE: Due to email list size limits, this patch is broken into 9 parts.]
Background
----------
An overview email, describing the UPC-related changes is here:
https://gcc.gnu.org/ml/gcc-patches/2015-12/msg00005.html
The GUPC branch is described here:
http://gcc.gnu.org/projects/gupc.html
The UPC-related source code differences are summarized here:
http://gccupc.org/gupc-changes
All languages (c, c++, fortran, go, lto, objc, obj-c++) have been
bootstrapped; no test suite regressions were introduced,
relative to the GCC trunk.
If you are on the cc-list, your name was chosen either
because you are listed as a maintainer for the area that
applies to the patches described in this email, or you
were a frequent contributor of patches made to files listed
in this email.
In the change log entries included in each patch, the directory
containing the affected files is listed, followed by the files.
When the patches are applied, the change log entries will be
distributed to the appropriate ChangeLog file.
Overview
--------
Libgupc is the UPC runtime library, for GUPC. The configuration,
makefile, and documentation related changes have been broken out into
separate patches.
As noted in the ChangeLog entry below, this is all new code.
Two communication layers are supported: (1) SMP, via 'mmap'
or (2) the Portals4 library API, which supports multi-node
operation. Libgupc generally requires a POSIX-compliant target OS.
The 'smp' runtime is the default runtime. The 'portals4'
runtime is experimental; it supports multi-node operation
using the Portals4 communications library.
Most of the libgupc/include/ directory contains standard headers
defined by the UPC language specification. 'make install' will
install these headers in the directory where other "C"
header files are located.
