* configure.ac, check/Makefile.am, doc/Makefile.am: Do not explicitly link to -ldl, but instead autodetect the library with dlopen, dlsym, etc. * check/lightning.c: Add workaround to apparently buggy getopt in HP-UX that sets optind to the wrong index, and use RTLD_NEXT on HP-UX instead of RTLD_DEFAULT to dlsym global symbols. * include/lightning.h: Rework definitions of wordsize and byte order to detect proper values on HP-UX. * lib/lightning.c: Minor correction to use MAP_ANONYMOUS instead of MAP_ANON on HP-UX. * lib/jit_hppa.c: Float arguments must be passed on integer registers on HP-UX, not only for varargs functions. Add code to properly clear instruction cache. This was not required on Debian hppa port, but may have been working by accident. * lib/jit_hppa-cpu.c: Follow pattern of HP-UX binaries and use bve,n instead of bv,n to return from functions. * lib/jit_hppa-fpu.c: For some reason "fst? frX,rX,(rY)" did not work on the tested computer (HP-UX B.11.23 U 9000/785 HP-UX) so the code was changed, at first for __hpux only to add the base and offset register and use the instruction with an immediate (zero) offset.

Programming Note
|
|
|
|
The minimum spacing that is guaranteed to work for "self-modifying code" is
|
|
shown in the code segment below. Since instruction prefetching is permitted,
|
|
any data cache flushes must be separated from any instruction cache flushes
|
|
by a SYNC. This will ensure that the "new" instruction will be written to
|
|
memory prior to any attempts at prefetching it as an instruction.
|
|
|
|
LDIL l%newinstr,rnew
|
|
LDW r%newinstr(0,rnew),temp
|
|
LDIL l%instr,rinstr
|
|
STW temp,r%instr(0,rinstr)
|
|
FDC r%instr(0,rinstr)
|
|
SYNC
|
|
FIC r%instr(rinstr)
|
|
SYNC
|
|
instr ...
|
|
(at least seven instructions)
|
|
|
|
This sequence assumes a uniprocessor system. In a multiprocessor system,
|
|
software must ensure no processor is executing code which is in the process
|
|
of being modified.
