Commit 10bd3b613fd389da7640902c2b88a6e36088c920. Native DFFI was
replaced by a libffi long time ago,
but we have maintained the code as a fallback. Due to small number of
supported platforms and no real use it has been removed in 2016.
Commit 61500316b7ea17d0e42f5ca127f2f9fa3e6596a8. Broken GC is
replaced by BoehmGC library. This may be added back as a fallback in
the near future.
3bd9799a2fef21cc309472e604a46be236b155c7 removes a leftover
(apparently gbc.d wasn’t bdwgc glue).
Commit 41923d5927f31f4dd702f546b9caee74e98a2080. Green threads
(aka light weight processes) has been replaced with native threads
implementation. There is an ongoing effort to bring them back as an
alternative interface.
Commit 9b8258388487df8243e2ced9c784e569c0b34c4f This was
abandoned effort of changing the compiler architecture. Some clever
ideas and a compiler package hierarchy. Some of these things should be
incorporated during the evolution of the primary compiler.
Commit 5042589043a7be853b7f85fd7a996747412de6b4. This old loop
implementation has got superseded by the one incorporated from
Symbolics LOOP in 2001.
Commit edfc2ba785d6a64667e89c869ef0a872d7b9704b. Removes
pre-gmp bignum code. Name comes probably from “extended arithmetic”,
contains multiplication and division routines (assembler and a
portable implementation).
Commit 6ff5d20417a21a76846c4b28e532aac097f03109. Old unification
module (logic programming) from EcoLisp times.
Commit 72e422f1b3c4b3c52fa273b961517db943749a8f. Partially
broken. Tests left in package-extensions.lsp.
Commit c3244b0148ed352808779b07b25c3edddf9d7349. Works fine but
provides no real gain and is limited to intel.
Commit 618f6e92e8144f7b95bc36b42a337c212bacc8e7. Disabled by
default, practically not tested, works on limited number of platforms.
