 | [GCC](https://gnu.org/software/gcc/)      | 4.4.7    | [2012-03-13](https://gcc.gnu.org/develop.html) ² | Support for “Generic COFF” in general was [dropped following the GCC 4.4 release series](https://gcc.gnu.org/gcc-4.4/changes.html).  As the last GCC release to support h8300-\*-coff (c.f. the lack of support for h8300-\*-coff [covered by the "h8300-\*-\*" case] in libgcc/config.host in later versions), the flag `--enable-obsolete` _must_ be used when configuring. |
 | [GCC CIL Front End](https://gcc.gnu.org/projects/cli.html) | 4.3.0-2007-12-13 | [2011-06-20](https://gcc.gnu.org/git/?p=gcc.git;a=shortlog;h=refs/vendors/st/heads/cli-fe) (final commit) | Work was done on separate branches, and front end work was later forked off from back end work.  Earlier coding was against GCC 4.3 before later skipping to GCC 4.5 (in which h8300-\*-coff was no longer supported). |

Versions 2.0 and later fail to build if targeting h8300-\*-coff <br/> NewLib is required to build libstdc++-v3 for targets such as h8300-hitachi-coff; otherwise, `configure` checks will fail with a “No support for this host/target combination” message. |

 | [GDB](https://sourceware.org/gdb/)      | 5.3      | [released 2002-12-12](https://sourceware.org/gdb/schedule/) | While a few later versions still supported h8300-\*-coff targets, the debugging capabilities built into BrickEmu (an emulator for the LEGO MindStorms RCX) are based on a built-in GDB server that implements the GDB 5 protocol. |
 | [GDB](https://sourceware.org/gdb/)      | 6.8      | [released 2008-02-29](https://sourceware.org/gdb/schedule/) | This version of GDB best aligns with the other packages in the GCC toolchain, in that it is able to be included in a combined toolchain build.  (Neither GDB 5.3 nor GDB 7.12.1 are able to be built that way.) |
 | [GDB](https://sourceware.org/gdb/)      | 7.12.1   | [released 2017-01-21](https://sourceware.org/gdb/schedule/) | While GDB 7.12.1 seems to indicate that h8300-\*-\*-coff targets are supported (note lack of support for h8300-\*-\*-coff [covered by the "h8300-\*-\*-\*" case] in bfd/config.bfd in later versions), compatibility has not been fully validated, as it was released well after h8300-\*-coff support had been dropped from other packages (for example, BinUtils and GDB are both developed in a single, common source repository). |
