Tag: cross-sparc-branch
Added: tools/cross-scripts/cross-x86-sparc.lisp
Modified: compiler/dump.lisp compiler/generic/new-genesis.lisp
compiler/ppc/parms.lisp compiler/sparc/parms.lisp
compiler/x86/parms.lisp
First cut at getting a cross-compile (Unicode) from x86 to sparc.
This needs more work, but the cross-compile does produce a sparc core
where the repl works. But currently that sparc core cannot rebuild
cmucl.
To do this, a version of cmucl from the HEAD branch needs to be
created to add the new slots to the backend. Then a new x86 build
needs to be done using these sources. Finally, a cross-compile can be
done using cross-x86-sparc.lisp as the cross-compile script.
compiler/dump.lisp:
o I think we actually do need to swap the string bytes when dumping
strings to a fasl because the fasl will eventually get loaded by the
target system, and the codes need to be in the correct byte order.
compiler/generic/new-genesis.lisp:
o LOAD-CHAR-CODE should test against C:*BACKEND*, not
C:*NATIVE-BACKEND*.
o Add MAYBE-BYTE-SWAP-STRING to swap the bytes of the character codes
if the *backend* and *native-backend* have different endianness.
o Swap the strings read from a fasl. The fasl should have strings in
the target endianness, but when we cold-load them, we need the
native endianness. (I think). This means swapping bytes in
COLD-LOAD-SYMBOL, FOP-UNINTERNED-SYMBOL-SAVE,
FOP-UNINTERNED-SMALL-SYMBOL-SAVE, FOP-STRING, FOP-SMALL-STRING.
o In MAKE-COLD-LINKAGE-VECTOR, byte swap the string before we store
the string to the core. The string in the linkage vector already
has the correct endianness, and string-to-core will swap the bytes.
(Not sure why the linkage string ares this way, though. This is a
hack.)
o Add optional swap-p paramter to COLD-REGISTER-FOREIGN-LINKAGE to
enable byte swapping of the symbol string. This is a hack to get
"call_into_c" into the correct byte order for the target and
MAKE-COLD-LINKAGE-VECTOR.
o Use the backend foreign-linkage-space-start and
foreign-linkage-entry-size for COLD-REGISTER-FOREIGN-LINKAGE. This
prevents the wrong addresses leaking into the target. (Previously,
the values form the native backend were getting used, which wreaks
havoc on the target since the addresses are not even close.)
compiler/ppc/parms.lisp:
o Set up the backend-foreign-linkage-space-start and
backend-foreign-linkage-entry-size with the correct values.
compiler/sparc/parms.lisp:
o Set up the backend-foreign-linkage-space-start and
backend-foreign-linkage-entry-size with the correct values.
compiler/x86/parms.lisp:
o Set up the backend-foreign-linkage-space-start and
backend-foreign-linkage-entry-size with the correct values.
tools/cross-scripts/cross-x86-sparc.lisp:
o New cross-compile script to do an x86 to sparc cross-compile. Needs
work.
