word_swap_page() should only touch each 32-bit word once to change
the byte order from ABCD to DCBA rather than twice doing a transform
of the entire region from ABCD to BADC and then again to DCBA
The compiler provided ntohl() usually gets favorable optimizations
applied, so use it for the byte reordering.
With word_swap_page() rewritten, byte_swap_word() is superfluous.
* added support for XNS networking via Dodo-Nethub
* NetHub connection now optional (only if -nh-host is given); released NetHub-related changes to 'ether.c' to the public domain
* Added file using-dodo-networking-with-maiko.md
Documentation for building and using the Dodo-networking addition to Maiko
* Added support for running Maiko unter cygwin/x86_64-x
* Migrate Addr68k/NativeAlignment{2,4} in Nethub code, move timer/async defines to platform.h
* added missing include <netinet/in.h> for FreeBSD
* updated 'compile-flags' with added flags
* splitted ether.c in 3 (_common, _sunos, _nethub)
* reworks/modifications for nbriggs' pull-request review comments
* addintional additions for nbriggs' pull-request review comments
* get the Lisp packet lengths with 'LispInt2CInt'
* renamed variables in dblwordsSwap to indicate it's about double-words
* fixed wrong preprocessor directive unnoticed by clang
* added networking choice option to cmake build, fix to printf warning
- for cmake specify the networking to use with -DMAIKO_NETWORK_TYPE=<type>
- with <type> one of: NONE, SUN_DLPI, SUN_NIT, NETHUB
- e.g.: cmake .. -DMAIKO_NETWORK_TYPE=NETHUB
* integrated improvement to sendPacket() proposed by nbriggs
* integrated fix for SIGBUS on 32-bit big-endian, provided by nbriggs
* MAIKO_ENABLE_ETHERNET should not be unconditionally set on Solaris systems
* Receiving an ethernet packet is an ether interrupt but not an i/o interrupt.

Addr68k_from_LADDR always produced a 2-byte aligned pointer which
was frequently cast to a type requiring 4-byte alignment.
This commit changes Addr68k_from_LADDR uses to one of two new
inline procedures, NativeAligned2FromLAddr or NativeAligned4FromLAddr,
which produce a result with the appropriate alignment for the context.
This permits checking for cases where the Lisp address is not
appropriately aligned for the usage context, and localizes compiler
warnings to these two procedures.
Similarly, the Addr68k_from_StkOffset macros are replaced by
NativeAligned2FromStackOffset and NativeAligned4FromStackOffset.
NativeAligned4FromLPage replaces Addr68k_from_LPAGE as page address
will always be at least 4-byte aligned.
LAddrFromNative, LPageFromNative, and StackOffsetFromNative complete
the set, replacing LADDR_from_68k, LPAGE_from_68k, and
StkOffset_from_68K (note K not k) respectively.
Instead of using a single macro that converts from a lisp pointer to
a native pointer to a 2-byte aligned item then perhaps casting to objects
that require 4-byte alignment... use separate functions for 2-byte and
4-byte aligned pointer results. The clients should be explicit about
which alignment they require, and the conversion functions can check
(perhaps in DEBUG mode) that the resulting pointer is on an appropriate
boundary.
This commit defines the functions but does not introduce any uses.
Many of the warnings were newly visible after the DBPRINT macro
was modified, but the pedantic warnings also caught existing printf
family usage which was not strictly correct.
Mostly replacing 0x%x with %p for pointers, adding (void *) for
those and other pointers, %td for ptrdiff_t, but also changing
some function parameters from UNSIGNED (uintptr_t) to int
where that was the more appropriate type.
Combines arith2.c ... arith4.c files and their associated header files
into new arithops.c/arithopsdefs.h files, and adjusts the CMakeLists.txt,
and old-style makefile-tail. Also updates makefile-dos,
inlnPS2.h, and inlndos.h to reflect these changes, though these are not
used.
Combines the array..array6 files and their associated header files
into new arrayops.c/arrayopsdefs.h files, and adjusts the CMakeLists.txt
and old-style makefile-tail to reflect these changes.
Remove unused #define PERCENT_OF_SCREEN in MyWindow.h
Move structures for dir.c to dirdefs.h where they are used
Resolve S_CHAR vs S_CHARACTER in favor of S_CHARACTER and cleanup #defines
Fix = vs == bug in FSDEBUG code in dir.c
Eliminate duplicate/unused constant definitions in gcr.c
Declare static internal function bytecmp in mkatom.c
Update many source and include files to include headers for what they use
If the debugging printf macros are elided by the preprocessor
rather than being removed by the compiler's optimizer then
the debugging statements may get out-of-date as variables are
modified. Wrap the non-debug case in "if (0) ..." instead.
* arithmetic opcode implementations should return LispPTR rather than int
* all callers of ERROR_EXIT() have return type LispPTR, therefore ERROR_EXIT should too
* N_[I]GETNUMBER, [N_]ARITH_SWITCH need (int) casts for some large constants that would otherwise be unsigned
* Expand use of macro N_ARITH_BODY_1_UNSIGNED and correct types
* Remove unused macros N_ARITH_BODY_1 and N_ARITH_BODY_1_UNSIGNED
* Cast to correct type for storing to TopOfStack, and return type of TIMER_EXIT()
* Pedantic C compilers want an extern declaration separate from initialization
* Remove duplicate definitions for fns in initdspdefs.h from display.h
* Remove misleading comments on structure member offsets and reorder to minimize padding
