The actual Spike package consists of a whole bunch of libraries. This
installs a pkg-config file for each generated library, and a meta
pkg-config file (riscv-spike.pc) that links in all the other Spike
libraries except dummy_rocc (which I figure isn't interesting).
This allows me to package and install spike, and then use that package
to build an extension library (so I don't have to fork Spike for my
own ISA extension).
DESTDIR is a common make idiom. As per the GNU coding standards
https://www.gnu.org/prep/standards/html_node/DESTDIR.html
"DESTDIR is a variable prepended to each installed target file, like
this:
$(INSTALL_PROGRAM) foo $(DESTDIR)$(bindir)/foo
$(INSTALL_DATA) libfoo.a $(DESTDIR)$(libdir)/libfoo.a
The DESTDIR variable is specified by the user on the make command
line as an absolute file name. For example:
make DESTDIR=/tmp/stage install
DESTDIR should be supported only in the install* and uninstall*
targets, as those are the only targets where it is useful.
If your installation step would normally install /usr/local/bin/foo
and /usr/local/lib/libfoo.a, then an installation invoked as in the
example above would install /tmp/stage/usr/local/bin/foo and
/tmp/stage/usr/local/lib/libfoo.a instead."
The current Makefile.in uses DESTDIR, but has a slightly non-standard
behavior: the target install location doesn't include "$prefix". This
breaks package managers, because stuff ends up getting installed to
the wrong location.
Unfortunately the only way I can think of to fix this involves
silently changing the behavior of DESTDIR. Hopefully nobody is using
it...?
[port of 8a2088b59162fe16c16d26ddc1cfcaaaa8c4156f in riscv-fesvr]
We now use a heavily unrolled loop as the software I$, which allows the
host machine's branch target prediction to associate target PCs with
unique-ish host PCs.
Moved cross-compiler to /xcc/ rather than /
Added ISA sim in /sim/
Added Proxy Kernel in /pk/ (to be cleaned up)
Added opcode map to /opcodes/ (ditto)
Added documentation to /doc/
