GNU Legacy Toolchain

A legacy GNU toolchain that includes binutils, gcc, gpc, gdb, and newlib. While primarily intended for building a cross-toolchain targeting Hitachi/Renesas H8/300 processors with the COFF (or, colloquially, HMS) format, this should work for other targets as well.

While this H8/300 target has sometimes been referred to as h8300-hitachi-hms, it is more properly identified as h8300-hitachi-coff.

Repository Creation Notes

Sources Versions Used

Last known versions to include support for h8300-*-coff

• BinUtils 2.16.1
  • Note lack of support for h8300-*-coff in gas/configure.tgt in later versions
• GCC 3.4.6
  • Last supported version is actually the GCC 4.4 series – note lack of support for h8300--coff (covered by the "h8300--*" case) in libgcc/config.host in later versions
  • So why GCC 3.4.6?
    • H8/300 was supported for the duration of the full GCC version series, with 3.4.6 closing the release series
    • Source code has been suppored by Debian package maintainers with maintance patches (gcc-h8300 package)
    • GPC integration is less robust in GCC 4
    • Created smaller binaries compared to the same builds created using GCC 4
      • Especially important on memory-constrained devices such as the LEGO MindStorms RCX
  • Resources
    • Build and Installation Configuration Documentation
    • Manual
      • Manual subsets and/or other formats (scroll down for the GCC 3.4.6 manuals section)
• GPC 2.1-20070904 – note the included README files
  • The GNU Pascal Manual
  • GPC website
    • Compilation and installation guide: Note the section covering pascal.install at the end
    • Cross-compilation guide
  • Source files from hebisch/gpc
  • Mailing list (no longer seems to be active)
    • Subscribe/Unsubscribe page
• GDB 7.12.1 – note lack of support for h8300-*-*-coff (covered by the "h8300-*-*-*" case) in bfd/config.bfd in later versions
• NewLib 1.19.0
  • Version 1.20.0 introduces incompatibilities with the binutil's version of libiberty (c.f. gcc list)
  • Versions 2.0 and later fail to build if targeting h8300-*-coff

Combined Folder Composition

Several folders are duplicated across the various project comprising the toolchain. Unfortunately, given the differing ages of the various releases, it does not seem that they can be readily combined into a single build.

Taking libiberty from binutils and the combining the gcc and binutils builds does seem to work, which at least eliminates the complications that would otherwise arise from having to build gcc and binutils separately.

Folder	gcc	binutils	newlib	gdb
bfd		×		×
cpu		×		×
etc		×	×	×
include	×	×		×
libiberty	×	×		×
opcodes		×		×
texinfo		×	×	×
zlib	×			×

The following were soft-linked in to create the combined source folder src-combined, which is then used as the source folder for builds:

• boehm-gc
• config
• fastjar
• gcc
• include
• intl
• libf2c
• libffi
• libjava
• libobjc
• libstdc++-v3
• zlib

Folders from BinUtils

• bfd
• binutils
• cgen
• cpu
• etc
• gas
• gprof
• ld
• libiberty
• opcodes
• texinfo

Folders from GPC

• ltconfig
• ltmain.sh
• Makefile.def

• newlib

Patches

The following patches were applied.

Binutils

Debian provides a binutils-h8300-hms package based on binutils 2.16.1 that includes several patch updates in the debian.tar.xz archive file available on that page. From the patches/series file in that archive (c.f. release versions here), available Debian patches include those lised below. Patches not marked with strikethrough have been applied here (unapplied patches are more Debian specific).
