parentUpgrade to v1.0prerelease-1 (diff)
Split the Modula-3 port into two pieces, creating a new port
"modula-3-lib". It installs only the shared libraries needed for executing Modula-3 programs. This saves a lot of disk space for people who need to run Modula-3 programs but don't need to build them. The original "modula-3" port now depends on this one, and uses it to install the compiler and the rest of the development system. Also, everything is now built with optimization. I have been testing this for at least a month, and haven't seen any problems from it. It makes the libraries and executables substantially smaller. This new port also includes some hooks that will make SOCKS support possible in the near future.

+This port uses distfiles that I prepared specially for FreeBSD. The DEC
+SRC release of Modula-3 comes in the form of 3 compressed tar files
+totaling about 16 MB. A small fraction of that is actually needed.
+
+The FreeBSD distfiles are as follows.
+
+ m3-fbsd-src-3.6.tar.gz (required)
+
+ Sources for selected portions of the SRC release. These
+ files are unmodified; however, only a subset is included.
+ Files relating to platforms other than FreeBSD have been
+ omitted. Also, several large but rarely-used packages have
+ been left out.
+
+ m3-fbsd-m3cc-3.6.tar.gz (required)
+
+ Sources for the Modula-3 specific files making up the code
+ generator. As released by SRC, the code generator is a
+ slightly modified version of gcc-2.6.3. I have updated
+ the modifications to work with the newer gcc-2.7.2.1. Only
+ the files which differ from those in the FreeBSD gcc-2.7.2.1
+ sources are included in this distfile.
+
+ m3-fbsd-gcc-3.6.tar.gz (optional)
+
+ Sources for the needed portions of gcc-2.7.2.1 which are
+ identical to those included in the FreeBSD system sources.
+ Many systems have these files online in "/usr/src/contrib/gcc".
+ The Makefile looks for them there first, and uses the online
+ files if they are present. Only if the necessary files
+ are missing is this distfile fetched and used.
+
+ m3-fbsd-boot-3.6.tar.gz (optional)
+
+ A statically-linked FreeBSD executable for the Modula-3
+ compiler. A working compiler is needed, because the compiler
+ is itself written in Modula-3. The Makefile looks for this
+ executable on the system; it may already be present from
+ an earlier version of the port. If found, the version
+ already on the system is used. Otherwise, this distfile
+ is fetched and used.
+
+Also in the current directory are files named "T.*" and "X.*". These
+contain lists of files and wildcards specifying the files to be included
+and excluded from each distfile. For example, "m3-fbsd-src-3.6.tar.gz"
+can be reconstructed using the following commands:
+
+ make extract
+ cd work
+ tar -czvf m3-fbsd-src-3.6.tar.gz -T ../files/T.src -X ../files/X.src

+This inserts a thread-safe version of malloc into the "m3core"
+package. It solves some very obscure problems that were caused by
+back-door entries into malloc from <*EXTERNAL*> procedures, without
+locking the heap. These allowed multiple threads to enter the
+malloc package at once, and led to scribbling in memory and subsequent
+core dumps.
+
+This also adds separate wrapper files for network related functions to the
+m3makefile, for SOCKS support.

+Bug fix from SRC:
+ bug assigning arrays
+
+ This patch applies to all platforms.
+
+ The Modula-3 language definition says that it is possible to assign
+ one array to another if they have the same shape. There is a bug
+ in the compiler front-end that causes the compiler to report that
+ two array types are not assignable if they have different base
+ indices, even if they have the same size.
