Revert the previous change to fix debug:arg/trace issue.  Instead, use
Carl's suggestion and define new SC numbers for the xmm registers
instead of overloading the x87 fpu registers and the xmm register
SC's.

bootfiles/20a/boot-2010-06-cross-x86.lisp:
o New file needed for cross-compiling this change.

code/x86-vm.lisp:
o Revert previous change.

compiler/x86/sse2-c-call.lisp:
o Use xmm0-tn instead of fr0-tn.  No functional change, but makes the
  code more readable.

compiler/x86/vm.lisp:
o Increase the number of float registers from 8 to 16 (8 more for SSE2
  registers).
o Define new xmm<n> registers
o Update the locations with the new sse2 SC locations for single-reg,
  double-reg, double-double-reg, complex-single-reg,
  complex-double-reg, and complex-double-double-reg storage classes.

lisp/Darwin-os.c:
o Revert previous change.
o Update os_sigcontext_fpu_reg to support the xmm registers.

lisp/Linux-os.c:
o Update os_sigcontext_fpu_reg to support the xmm registers.

Fix issue where the debugger (and TRACE) would get the wrong
floating-point values for arguments because the x87 registers were
used instead of the sse2 registers in the sigcontext.

code/x86-vm.lisp:
o For SSE2 on Mac OS X, call os_sigcontext_fpu_reg_sse2 to get the
  SSE2 register values from the sigcontext.

lisp/Darwin-os.c:
o Add os_sigcontext_fpu_reg_sse2 to get the SSE2 floating point
  values.

Merge intl-branch 2010-03-18 to HEAD.  To build, you need to use
boot-2010-02-1 as the bootstrap file.  You should probably also use

while building.

:SSE2 should not be a runtime feature saved in internals.h.  This is
handled by the makefile which sets -DFEATURE_SSE2 appropriately
because :SSE2 is a lisp feature saved in internals.inc.

This was causing the C code to be rebuilt when building x87 and then
sse2 in the same tree.  It's not necessary to do that and should not
be done.

Switch the FreeBSD port to use the common floating point trap handling
code.  Rather than introduce a new FreeBSD case to the x86 sigcontext
member accessor routines, collapse all of the system specific routines
down to a common set of routines.

* code/debug-int.lisp - Disable some Darwin-specific code to debug
  NULL mcontext pointers.

* code/float-trap.lisp - Remove ancient FreeBSD-specific code for
  handling floating point signals.

* code/macros.lisp, code/sap.lisp, compiler/saptran.lisp - Include the
  SAP-REF-LONG setter by default on the x86.

* code/x86-vm.lisp - Remove operating system specific sigcontext
  definitions and sigcontext accessors.  Define the alien sigcontext
  as a system area pointer.  Replace the sigcontext accessors with
  foreign function calls that mask the complexity of the underlying
  sigcontext member access.

* compiler/x86/float.lisp - Unconditionally define STORE-LONG-FLOAT.
  This function is used by the %SET-SAP-REF-LONG VOP that underlies
  the SAP-REF-LONG setter.

* compiler/x86/sap.lisp - Unconditionally define %SET-SAP-REF-LONG.
  In the case where there is not a distinct LONG-FLOAT type, admit
  DOUBLE-FLOAT values instead.  The x87 automatically widens values
  pushed onto stack.  This mirrors the behavior of the SAP-REF-LONG
  VOP.

* lisp/Darwin-os.c, lisp/Linux-os.c - Define functions to access
  sigcontext members of interest to Lisp.  Delete the sc_reg function
  and replace its uses with os_sigcontext_reg which is more suitably
  typed.

* lisp/FreeBSD-os.c - Define functions to access sigcontext members of
  interest to Lisp.  We need to be careful about the SSE and non-SSE
  cases for retrieving x87 registers from the saved machine state.
  Define a low-level SIGFPE handler to intercept floating point traps
  and restore the cleared status word bits based on the signal code.
  Get rid of sc_reg for the reasons noted above.

* lisp/Darwin-os.h, lisp/FreeBSD-os.h - Declare the restore_fpu
  function and define a specialized RESTORE_FPU macro.  Remove the
  sc_reg prototype.

* lisp/Linux-os.h - Remove the sc_reg prototype.

* lisp/os.h - Add prototypes for the new os_sigcontext functions.

* lisp/x86-lispregs.h - Redefine SC_REG and SC_PC to expand out to the
  new os_sigcontext functions.  Redfine SC_SP to expand out to SC_REG.
  Eliminate all platform-specific defintions of SC_PC and SC_SP.

anymore.

o Fix typo:  It's fpstate, not ftpstate.
o Fix dereferencing of the fpstate, which is not in the sigcontext
  anymore.  It's in the sc-mcontext slot of the sigcontext now.

On x86 FreeBSD and Linux, change the way foreign symbol addresses are resolved.
They now go through a table -- effectively a new space in the core file.
Function references are resolved lazily, data references are resolved on startup
and when a .so is loaded.  The end result is that cores can be dumped that
contain references to symbols in shared libraries.  Also, the dependence of the core on addresses in the Lisp runtime is broken.

The linkage table feature is controlled by :linkage-table and LINKAGE_TABLE in C
runtime.  Several foreign symbols are now Lisp static symbols, so a cross
compile is required whether or not the new stuff is used.  I've checked in
boot4-cross-foreign-linkage.lisp that builds the compiler for linkage table; do whatever you usually do for the non-linkage table case:)  Seriously, lets start
a discussion on standardizing "cross compilation," not to mention the general
build procedure.

Changed the OpenBSD port to use dlopen+ld for FFI linkage, like
current Linux and FreeBSD/ELF do, although OpenBSD is still non-ELF.
Also changed the handling of leading underscores in alien names, by
moving the underscore addition to extern-alien-name, where it belongs,
and not foreign-symbol-address-aux.  This brings the x86 port in line
with the other ports, modulo the PVE_stub_ magic.  The changes
necessitate some bootstrapping code for BSD non-ELF platforms.

Added specialised port to NetBSD (1.5.2) on x86.  Since the code-base
was already cleaned up with the OpenBSD port, this doesn't require
massive changes.

Since current NetBSD is ELF-based by default, we don't make use of the
ELF feature, or in other words:  The presence of the NetBSD feature
implies ELF, since there is no support for non-ELF NetBSD.

Added specialised port to OpenBSD (2.9).  Many parts of the original
code which were previously conditionalized on :FreeBSD, are now
conditionalized on :BSD instead, with the :BSD feature now implying a
4.4BSD(lite2) derived OS.  This should make future BSD-ports easier.
FreeBSD and OpenBSD are differentiated by having either :FreeBSD or
:OpenBSD on the features list.

Currently the OpenBSD port does not have working ELF support, because
OpenBSD 2.9 is still non-ELF by default.  So don't put ELF on the
features list when building for OpenBSD, or fix the code to work
correctly in this case instead.

Improved support for (complex single-float) and (complex double-float)
types. Adds storage classes to the backend for these so they can be
stored in registers or on the stack without consing; new primitive
types etc. Also adds (simple-array (complex {single,double}-float))
array types to avoid consing and speed vectors operations.  All
these changes are conditional on the :complex-float feature. More work
is needed to exploit these changes: improving the type dispatch in the
various function; maybe compiler transforms or more VOPs to handle
common functions inline.

atomically test and set instance slots; translations of new function
%instance-set-conditional.
