A Long-Term Support (LTS) release of mspgcc is a release for a particular version of a major component, such as gcc 4.6.3, intended to be adopted by downstream packagers and to provide a level of stability in interface and features that does not apply to the main development. When bug fixes are back-ported to an LTS release, patches are made available. These patches are collected in the relevant subdirectory of LTS (e.g., LTS/20120406).
Patches are released periodically. Generally, notice is sent to the mspgcc-users mailing list.
The mspgcc patches intentionally do not add version information, as it is the responsibility of the packager to select from among the "official" patches provided here and any distribution-specific changes.
LTS release series starting with 20120406 will include the following content in the gcc-X.Y.Z/gcc/DEV-PHASE file, allowing the compiler release version to be identified with the -version option:
mspgcc LTS YYYYMMDD unpatched
Similarly, for binutils the file binutils-X.Y/bfd/version.h in the release will have the following line:
#define BFD_MSPGCC_VERSION LTS YYYYMMDD unpatched
Downstream maintainers should update this file to represent in some way the set of patches that have been applied to the release. If all and only official mspgcc LTS patches are applied, one possibility is to replace "unpatched" with "patched to YYYYMMDD" representing the date of the most recent patch download from the corresponding LTS patch directory under https://sourceforge.net/projects/mspgcc/files/Patches/LTS/.
Downstream packagers may track this area using:
git checkout -b patches git://mspgcc.git.sourceforge.net/gitroot/mspgcc/mspgcc
