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 PAGE_SIZE. * elf.c - add includes that were implicitly depended on. * lisp.c - remove unused system includes including sys/param.h which redefines PAGE_SIZE.

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.

* 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 code.

reg_NARGS macro on these targets and use SC_REG to replace open-coded assignments to platform specific sigcontext members in interrupt.c and os-common.c. This code could be simplified further by merging the x86 and AMD64 cases into the general case.

feature :stack-checking because it's not implemented for other systems/architectures yet.

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.
