Patches

Known patches are listed below. Those not marked with strikethrough have been applied to the code in this respository. Unapplied patches might be specific to a particular distribution or duplicate patches from other sources.

Please note that these patches do not reflect the only changes to the code. Other changes were made as needed to address various build issues and can be reviewed in the commit history.

Binutils 2.16.1

BFD from GDB 6.8

With two minor tweaks to binutil’s bfd (adding BFD_HOSTPTR_T and bfd_fopen()), GDB 6.8 can also be included in this combined build. Both of these have been backported from the version of bfd that shipped with GDB 6.8.

Debian

Debian provides a binutils-h8300-hms package based on binutils 2.16.1 that bundles several patches. From the patches/series file in that archive (c.f. release versions here), available Debian patches include those lised below. Use this link to be redirected to the latest collection of stable patches. Generally, unapplied patches are more Debian specific.

GCC Multi-Version (3.4.6 and 4.4.7)

GCC No Build Info Patch

This patch was posted to the GCC mailing list on February 10, 2024, by Christophe Lyon (link), with the intent of always checking info dependencies. Within this project, that patch was leveraged in conjunction with addtional changes (c.f. commit: “Provide for skipping the build and install of info files”) to prevent the installation of (outdated) info files that would conflict with info files installed by newer GCC versions.

If desired, these info files may still be installed as a separate step via make install-info.

GCC 3.4.6

GNU GCC Post-Release Patches

Subsequent to the final release of GCC 3 (v3.4.6 on March 6, 2006), four additional patches were pushed to the releases/gcc-3.4 branch. Patch files are available in both *.diff and *.patch forms.

Applied? Patch File Name Notes
❌ m32r Three patches—all released later in 2006—pertain to m32r support but are superseded by more comprehensive patches from Debian (c.f. the Debian patch section).
❌ bison The fourth patch—from 2009—provides a fix for compatibility with bison 2.4.1. Superseded by the more recent pair of Bison patches from the Red Hat compatibility patches and Debian patches.

GCC 4.4.7

GCC Common Intermediate Language (CIL) Front End

The GCC front end for the Common Language Infrastructure (CLI) Common Intermediate Language (CIL) was a project to take compiled CIL as input and generate machine-executable code as output. After the front end was separated, the code was originally written against GCC 4.3 and then later updated to GCC 4.5.

Unfortunately, GCC 4.3 has internal compiler error (ICE) issues (causing builds of GCC targeting h8300-hitachi-coff to fail), and GCC 4.5 is after “generic coff” support was dropped from GCC. The patching done here attempts to get the Common Intermediate Language Front End (CIL FE) working with that skipped version—GCC 4.4.

An extract of this CIL FE from the GCC repositories is at BrickBot/gcc-cli-fe, and the patches and files here are based on that code, and the branches in that respository cover the following:

Branch Name Description
master The original, unedited branch with all files
h8300-coff-base Branch of the last commit against GCC 4.3 before GCC was updated to 4.5
h8300-coff Starting from branch h8300-coff-base, apply updates to make it buildable (but excluding libcilsupport)
h8300-coff-libcilsupport Adds updates to libcilsupport from where branch h8300-coff left off
post-h8300-cli-fe-squash Branch created for collapsing updates subsequent to the GCC 4.5 update into a single squash commit, from which patch files could then be generated

Starting with the migration from GCC 4.3 to 4.5, all subsequent CIL-specific commits have been captured as patch files. This complete set of patches can be found in the file post-h8300-cli-fe-squash.patch; however, to make it easier to work with the patches, this single file was split into several separate files based on the impacted functionality. From these, updates were make to GCC 4.4.7, working forward from the GCC 4.3-based code to the 4.5-based code.

Individual Patch Files Description
post-h8300-cli-fe-squash-just-cil.patch Changes to code under gcc/cil
post-h8300-cli-fe-squash-just-cil-parser.patch Changes specific to gcc/cil/parser.c
post-h8300-cli-fe-squash-just-gcc-common.patch Changes to “common” files (e.g. Makefile, configure, gcc/common.opt, gcc/config/*)
post-h8300-cli-fe-squash-just-libcilsupport.patch Changes specific to libcilsupport

Additionally, there are several auto-generated *.h files that unfortunately aren’t all fully autogenerated under GCC 4.4. In particular, the following files contained incomplete definitions when autogenerated under GCC 4.4, so “static” copies were capture from a build of the version based on GCC 4.5 and then referenced statically within the updates for GCC 4.4.

Incomplete Dynamically-Generated File #include’d by
gt-cil-bindings.h gcc/cil/bindings.c
gt-cil-stack.h gcc/cil/stack.c
gtype-cil.h gcc/cil/cil1.c

Red Hat

Red Hat provided backwards compatibility patches for GCC 4.4.

TODO: This set for GCC 4.4.7 includes 37 patches to be reviewed and (potentially) applied.

Debian

Debian provided sets patches for GCC 4.4.7, with the last set being versioned 4.4.7-8. Patches are embedded as a patch file itself (solely containing all new files, with no file edits) in gcc-4.4_4.4.7-8.diff.gz.

TODO: This set for GCC 4.4.7 includes 171 patches to be reviewed and (potentially) applied.

GCC Backported Parches

Skip Building (and Installing) Info Files

From the GCC mailing list in February 2024, this small patch enables skipping the building and installing of info files.

NewLib 1.19.0

While newlib-1.20.0 was technically the last version to support h8300-*-coff, version 1.20.0 introduces incompatibilities with version of libiberty used by the other tools supporting h8300-*-coff (c.f. gcc list), so newlib-1.19.0 is effectively the last version of NewLib to support h8300-*-coff.

Debian

While Debian did not provide a newlib-1.19.0 package, all patches from Debian’s packaging of newlib-1.18.0 appear applicable to newlib-1.19.0 as well.

Applied? Patch File Name Notes
✔ 60_newlib-libgloss-eabi.patch
✔ 61_newlib_arm_include.patch
✔ 62_long_double_infinity.patch
✔ 65_multiarch-headers.patch

GNU Debugger 5.3 (GDB)

Although GDB 6 is best suited to be built together as part of a combined GCC build with GCC 3.4.6 and GCC 4.4.7, the GDB server built into BrickEmu is based on the GDB 5 specifications, and so builds of GDB 5 a needed to be able to utilize the debugging capabilities of BrickEmu.

Debian

While Debian did not provide a gdb-5.3 package, some patches from Debian’s packaging of gdb-5.2 appear applicable to gdb-5.3 as well. No series file appears to exist for these patches, so order is based on the diff dates in the respective patch files.

GNU Debugger 6.8 (GDB)

GDB 6.8 is able to be built together with the rest of the GNU toolchain as part of a combined build.

GNU Debugger 7.12.1 (GDB)

The last version of GDB to technically support the h8300-hitachi-coff was 7.12.1. 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), in practice this is broken and will trigger various malloc errors on attempting to initiate a debug session. GDB 6 has not exhibited this issue.

Additionally, GDB 7 is incompatible with the shared libraries that are part of the GNU toolchain and must be built separately, but GDB 6 does maintain that compatibility and is able to built together with the rest of the GNU toolchain.

Debian

Debian never released a corresponding package for GDB 7.12.1 (c.f. list), but it did maintain a package for version 7.12 which included a number of patches (c.f. patch descriptions and patch ordering (series file)).
