Distribute prebuilt bootstraps for common hosts
* am/bootstrap.am: New file, factored out of bootstrap/Makefile.am. * bootstrap/Makefile.am: Use bootstrap.am. * prebuilt/Makefile.am: * prebuilt/i686-pc-linux-gnu/Makefile.am: * prebuilt/mips-unknown-linux-gnu/Makefile.am: * prebuilt/x86_64-unknown-linux-gnu/Makefile.am: New files. * configure.ac: Output the prebuilt/ makefiles. * Makefile.am: Descend into prebuilt/ when making dist. * meta/uninstalled-env.in: Arrange to put prebuilt/ in the beginning of the GUILE_LOAD_COMPILED_PATH. Also fix a case where bootstrap/ wasn't being correctly added to the load path.

# Guile Scheme is mostly written in Guile Scheme. Its compiler is
|
||||
# written in Guile Scheme, and its interpreter too. However, it is not
|
||||
# bootstrapped from itself: Guile includes a minimal interpreter written
|
||||
# in C as well which can load the compiler, enough to compile the
|
||||
# interpreter written in Scheme. That compiled interpreter written in
|
||||
# Scheme is then used to compile the rest of Guile, including the
|
||||
# compiler itself.
|
||||
#
|
||||
# The problem is, this process takes a long time, and for people
|
||||
# installing Guile from source, it's their first experience of Guile: an
|
||||
# hour-long bootstrap. It's not the nicest experience. To avoid this,
|
||||
# in our tarballs we pre-build object files for the essential parts of
|
||||
# the compiler.
|
||||
#
|
||||
# In the future we will do native compilation and so we will need to
|
||||
# precompile object files for all common host types. Still, since we
|
||||
# use ELF everywhere, there will be many host types whose compiled files
|
||||
# are the same: because Guile incorporates its own linker and loader for
|
||||
# compiled Scheme files, any AArch64 machine, for example, is going to
|
||||
# have the same compiled files. So, for the variants that will be the
|
||||
# same, we compile one target triple, and symlink the similar targets to
|
||||
# that directory.
|
||||
#
|
||||
# The current situation though is that we compile to bytecode, and there
|
||||
# are only four variants of that bytecode: big- or little-endian, and
|
||||
# 32- or 64-bit. The strategy is the same, only that now
|
||||
# arm64-unknown-linux-gnu will link to x86_64-unknown-linux-gnu, as they
|
||||
# have the same word size and endianness. A pending issue to resolve is
|
||||
# how this wil deal with architectures where longs are 32 bits and
|
||||
# pointers are 64 bits; we'll let the x32 people deal with that.
