Just checking here -- this is still correct for flushing the
instruction caches?
#define CLEAR_CACHE do {\
void *v=memory->cfd.cfd_start,*ve=v+memory->cfd.cfd_size; \
register unsigned long _beg __asm ("a1") = (unsigned long)(v); \
register unsigned long _end __asm ("a2") = (unsigned long)(ve);\
register unsigned long _flg __asm ("a3") = 0; \
__asm __volatile ("swi 0x9f0002 @ sys_cacheflush" \
: "=r" (_beg) \
: "0" (_beg), "r" (_end), "r"(_flg)); \
} while (0)
I assume so, as it is working for gcl 2.6.7, but I still get for
2.7.0:
;; Compiling ../lsp/gcl_listlib.lsp.
;; End of Pass 1.
;; End of Pass 2.
;; OPTIMIZE levels: Safety=3, Space=0, Speed=3, (Debug quality ignored)
;; Finished compiling ../lsp/gcl_listlib.o.
;; Loading /build/buildd/gclcvs-2.7.0/lsp/gcl_listlib.o
/bin/sh: line 1: 32335 Done echo '(time (let ((*features*
(cons :pre-gcl *features*)))(load "boot.lisp")))'
32336 Illegal instruction | ./saved_pre_gcl
