Revision 1.60.24.1 - (hide annotations)
Mon Nov 2 14:29:46 2009 UTC (4 years, 5 months ago) by rtoy
Branch: amd64-dd-branch
Changes since 1.60: +34 -1 lines
(Oops.  Previous checkin went to wrong branch.  Here is the commit
log, again.)

This large checkin brings the amd64 port up-to-date with the current
sources.  No real attempt has been made to make it work, but the
cross-compile does create a kernel.core, and the C code compiles (on
openSuSE 10.3).  The resulting kernel.core does not yet work.

Use cross-x86-amd64.lisp as the cross-compile script.  This is
intended to be cross-compiled using the 20a release for Linux, and
only supports x87.  The sse2 support has not be ported yet.

tools/cross-scripts/cross-x86-amd64.lisp:
o Update cross-compile with some missing constants, and frob new
  symbols.

tools/clean-target.sh:
o Remove amd64f files too.

code/pred.lisp:
o Define predicates for double-doubles for bootstrapping to work
  around recursive known function problems with these predicates.

code/sap.lisp:
o Define int-sap with (unsigned-byte 64) type declaration.  (May not
  be needed?)

code/unix-glibc2.lisp:
o Build fails defining map_failed to (int-sap -1).  Just hard-wire to
  0 for now so we can build.

compiler/float-tran.lisp:
o Add missing conditional for %complex-double-double-float.

compiler/amd64/float.lisp:
o Merge double-double support for amd64.  Not really tested yet.

compiler/amd64/parms.lisp:
o Update to match x86 build.  In particular, get the space address
  correct and update the static symbols.

compiler/amd64/type-vops.lisp:
o DYLAN-FUNCTION-HEADER-TYPE no longer exists.

compiler/amd64/vm.lisp:
o Add double-double storage classes and register definitions.

lisp/Config.amd64:
o Bring in line with Config.x86 and friends.

lisp/Linux-os.c:
o Bring amd64 code up-to-date with x86/linux code.

lisp/Linux-os.h
o Need to include sys/ucontext.h to get ucontext defined.  (Why?)
o Also define __USE_GNU so we get the register offsets in the ucontext
  defined.  (Why?)

lisp/amd64-arch.c:
o Change struct sigcontext to os_context_t.
o Use SC_PC instead of context->sc_pc.
o Merge some changes in from x86 version, like SC_EFLAGS.  May need
  more work.

lisp/amd64-assem.s:
o Use rbx instead of ebx for jmp.

lisp/amd64-lispregs.h:
o Define SC_REG, SC_PC, SC_SP using the new x86 style.

lisp/backtrace.c:
o Remove inline assembly for now until I figure out what the amd64
  version should be.

lisp/gencgc.c:
o Conditionalize out weak hash table support for now.

lisp/gencgc.h:
o Set PAGE_SIZE for amd64.  (Is 4096 right?)

lisp/globals.h:
o Export current_dynamic_space_free_pointer and
  current_auto_gc_trigger like for x86.
