feature :stack-checking because it's not implemented for other systems/architectures yet. It is currently known to work on FreeBSD 4.8-RC/x86 and Debian 2.2.20/x86. * bootfiles/18e/boot3.lisp: New boot file, well, only a description of the boot procedure since no boot file is needed. * lisp/x86-validate.h (SIGNAL_STACK_START, SIGNAL_STACK_SIZE) [__FreeBSD__, __linux__]: New defines. (CONTROL_STACK_SIZE) {__FreeBSD__, __linux__]: Adjust for signal stack. * lisp/validate.c (validate) [RED_ZONE_HIT]: Call os_guard_control_stack. Some cleanup. * lisp/os.h (BOTH_ZONES, YELLOW_ZONE, RED_ZONE): New enums. Add function prototypes. * lisp/interrupt.c (interrupt_install_low_level_handler) [RED_ZONE_HIT]: Deliver protection violations on a dedicated signal stack. * lisp/os-common.c (os_stack_grows_down_1, os_stack_grows_down): New functions. (guard_zones, control_stack_zone, os_guard_control_stack) (os_control_stack_overflow) [RED_ZONE_HIT]: New functions. (os_control_stack_overflow) [!RED_ZONE_HIT]: Dummy function. * lisp/Linux-os.c (sigsegv_handler) [RED_ZONE_HIT]: Handle control stack overflows. * lisp/FreeBSD-os.c: General cleansing. (sigbus_handler) [RED_ZONE_HIT]: Handle control stack overflows. * lisp/FreeBSD-os.h (PROTECTION_VIOLATION_SIGNAL): New define. * lisp/Linux-os.h (PROTECTION_VIOLATION_SIGNAL): New define. * compiler/x86/system.lisp (lisp::%scrub-control-stack): Change defknown from sys:scrub-control-stack. (%scrub-control-stack): Rename VOP. * code/lispinit.lisp (os-guard-control-stack) [#+stack-checking]: Define alien os_guard_control_stack. (%scrub-control-stack) [#+x86]: New function. (scrub-control-stack) [#+x86]: Call %scrub-control-stack, call os-guard-control-stack if #+stack-checking. * code/interr.lisp (yellow-zone-hit, red-zone-hit) [#+stack-checking]: New functions. * code/error.lisp (stack-overflow) [#+stack-checking]: New condition. * compiler/generic/new-genesis.lisp (finish-symbols) [#+stack-checking]: Add symbols for control stack checking. * compiler/x86/parms.lisp (static-symbols): Likewise.

o Conditionalized some code that is only used in linkage-table builds on :linkage-table and LINKAGE_TABLE respectively. o Modernized undefined_ff_tramp based on recent changes, and renamed it to undefined_foreign_symbol_trap, because it really isn't a trampoline. o Conditionalized a stray puts(...,dlerror()) in Linux-os.c on DEBUG o Installed an error reporter for UNDEFINED_FOREIGN_SYMBOL_ERROR, which for now signals a simple-program-error. We might want to introduced a new condition UNDEFINED-FOREIGN-SYMBOL or something, which could also be used by the old foreign linkage code.

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.

(signed-byte 16), (signed-byte 30), (signed-byte 32). These patches include the general support and the x86 backend support; more to follow. The important changes are conditional on the :signed-array feature so shouldn't affect the source without this feature. This work has been driven by Raymond Toy.

Fixed up ERROR-ERROR in various ways: -- We now call STREAM-INIT to attempt to fix up the streams, rather than setting *TERMINAL-IO* to the (no longer defined) variable *REAL-TERMINAL-IO*. -- We now use WITH-STANDARD-IO-SYNTAX in case someone has mucked up the printer control variables. -- The message now mentions *maximum-error-depth*, which is now exported from KERNEL.
