christos 60dd5ceebe printf -> kprintf, sprintf -> ksprintf 1996-10-11 00:06:28 +00:00
cgd 472889f8e4 moved to aout_machdep.h (via repository copy) 1996-10-08 12:57:37 +00:00
scottr f8b0c86aa8 The 68LC040 generates a format 4 stack frame for floating point 
exceptions, which puts the address of the instruction we faulted
on in a different location.  Copy it and handle as we normally would,
restoring the saved PC before returning.

The FPE should probably be reworked to take advantage of the 68LC040's
precalculated effective address, at some point.

scottr d12b257695 Fix FMOVEM emulation; postincrement modes use different ordering than 
predecrement modes, per 68K Programmer's Manual p. 5-88.  Pointed out
by Takeshi Nakayama <takeshi@sakabe.nuie.nagoya-u.ac.jp>, verified by me.

ws 5804d3f648 PowerPC port 1996-09-30 16:34:14 +00:00
jtc d137b0e8ba Added new macro _PROF_PROLOG which contains the code sequence needed 
to call mcount().  This is needed because the ``link a6,#0'' insn used
trips up gcc's ANSI preprocessor (A # in a function-type macro must be
followed by a macro argument).  _PROF_PROLOG is also used in the i386
asm.h.

Solaris' asm_linkage.h has a MCOUNT macro similar to _PROF_PROLOG
except it expands to different code sequences based on whether a
function is being compiled with "prof" or "gprof" instrumentation.

I also discovered that the m68k ALTENTRY is very different than the
implementation used by other NetBSD ports.  Usually ALTENTRY simply
provides an alternate function entry point.  The m68k version takes a
second argument and jumps inside the second function when profiling is
enabled.  The m68k behavior is similar to the ENTRY2 macro found in
solaris.

Providing ENTRY2 and changing all the code that uses ALTENTRY to use
it would be a desirable change.

leo 2eccad6548 Add macro's that do bclr/bset in a single instruction. 1996-09-16 06:03:58 +00:00
thorpej 22adc20819 Add an FPU_UNKNOWN constant; just a placeholder for any unknown FPU. 1996-09-12 02:52:34 +00:00
thorpej 521a717f6d Factor out common Motorola 68k CPU definitions from the m68k port 
cpu.h header files.

Some more work could be done here, but it's a good start.
 1996-09-11 00:08:52 +00:00
thorpej 73a5b90800 Pull in the COMPAT_M68K4K stuff when appropriate. 1996-09-10 22:07:10 +00:00
thorpej c5e5dec3b7 All of the m68k ports' exec.h's were essentially the same. Merge them. 
Override the N_PAGSIZ() macro; this one checks the MID of the executable
and returns the appropriate page size.
 1996-09-08 00:57:29 +00:00
thorpej f124a6aaa9 Back out previous; this is a bigger problem than I expected. 1996-08-14 00:32:53 +00:00
thorpej a05a1045f7 The htonl(), htons(), etc. functions return u_long and u_short. Add 
casts to the big-endian versions of these calls so that the compiler
won't complain when they're passed as arguments to printf().
 1996-08-14 00:07:35 +00:00
jtc d69119311f Provide alternate memmove() entrypoint for memcpy(). This will help 
in the transition from b*() to mem*().

is 51e832dc49 Fix a few off-by-one errors in bitnumbers used by print_fcode. 
ptestX fc,<ea>,M used to be printed with the wrong semantics of the fc
field, and could panic the kernel if fc was interpreted as a register number.

is cb5f8c53ac Now that our as pretends to understand the M68060 cpu, use -m68060 instead 
of -m68040 to avoid confusion.

errors. Fixed them. Thanks to Bernd Ernesti for the early report.

jtc 2ce5f1478b Add _BSD_WINT_T_ definition so we can handle wint_t type added in NA1. 1996-03-16 01:31:45 +00:00
is 905b10d4bc M68060 additional frame formats and bits. Closes PR 1174. 
This shouldn't break anything; I find ... grep ... all the relevant
kernel sources subdirecotry trees I could think of for the defines
that don't use the new FSLW or FPF6 prefix. But in case it does anyway,
tell me immediately.

gwr 19d5694f93 Remove the hack that faked up an "ssp" value. It is now up to 
locore.s to put the right sp in the frame.  Also move memory
access code into db_memrw.c so it can be taken separately.
