Patch from Stelian Ionescu on cmucl-imp, 2010/02/01:

    When run on a kernel compiled without COMPAT_BRK CMUCL segfaults,
    so I copied the kludge used by SBCL - check the current
    personality, and if necessary, enable ADDR_NO_RANDOMIZE and
    re-exec itself.

o Check for personality and rexec if necessary.

o New prototype for os_init needed because it needs argv and envp.

o Update call to os_init, which needs argv and envp now.

   Added SSE2 support to `os_sigcontext_fpu_modes' and `restore_fpu'
   -- essentially fixing the trap handling.  This includes changing
   the way FP state control and status words are combined in the
   returned value -- this is now in line with the way this return
   value is built on Linux and Darwin.


  Added SSE2 support and did general maintenance/reorganization while
  I was there.

The FreeBSD-os.h header imported headers that its definitions did not
make direct use of.  Remove the includes of these headers and fix-up
several files that indirectly depended on them.

* FreeBSD-os.c - add stdio.h and unistd.h includes that were
  implicitly depended on.  Remove unused or commented system includes.

* FreeBSD-os.h - remove unused includes.  Include signal.h to directly
  provide the SIGBUS, SIGSEGV, and sub-code definitions.  Redefine
  os_vm_address_t and os_vm_size_t in terms of standard types.  Now
  that the sys/param.h include is gone we no longer need to undefine

* elf.c - add includes that were implicitly depended on.

* lisp.c - remove unused system includes including sys/param.h which
  redefines PAGE_SIZE.

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

* 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

* 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.

Minor changes to support the latest betas of FreeBSD 7.

* Update the Config file to detect the GCC version at build time and
  use -iquote instead of -I- if we are not using GCC 2 or 3.  This
  silences the unsilenceable deprecation message emitted by GCC 4.

* Check the FreeBSD version at compile time and switch the protection
  violation signal to SIGSEGV if we are on a version of FreeBSD 7 that
  will deliver a SIGSEGV instead of a SIGBUS for access errors.

* Install sigbus_handler to handle whatever UNIX signal the macro
  PROTECTION_VIOLATION_SIGNAL expands to.  Get rid of the useless
  sigsegv_handler.  Add the PROTECTION_VIOLATION_CODE macro so we do
  not have to conditionalize the check that guards the write barrier

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.
