"warning: empty expression statement has no effect; remove unnecessary ';' to silence this warning" [-Wextra-semi-stmt]

Review this commit with "git diff -w ..." to make it easier to see changes other than indentation caused by
the addition of do { ... } while (0) around many macro definition bodies.
...in preparation for editing macro definitions to wrap in do {} while (0)
or other adjustment to make them complete statements without unnecessary
semicolons.
This programmatic reformatting should not introduce any functional changes.
This was like `ldeether`, but for SunOS4 with a color display. It
isn't needed any longer as on Solaris, we have `ldeether`, no color
display, and that code already works, unlike this one.
This is not used in Medley (the MISCN-TABLE-LIST doesn't include
the required constants), nor does anything use or reference this
code. It also won't compile as it needs some routines that are
missing from our code.
This isn't used and if it were, it wouldn't compile. It calls
`ufn`, which doesn't get compiled in either (unless `C_ONLY`
is defined, which it isn't, and if it were, that wouldn't
compile either due to a missing `StkLim0`).
A subsequent PR will remove `ufn` and related code.
* ForkUnixShell() can be a static procedure
* Restructure SAFEREAD() to be a little clearer
* Convert unixjob type field defines to an enum and fix related unhandled switch cases.
* Use local declaration of loop variables in for-loop, removing register attributes
* Restructure SAFEREAD() to be a little clearer
* Send and receive 2 additional bytes for pid.
* Prefer standard C99 "inline" over "__inline__" for SAFEREAD
* Address older versions of C compiler which don't have __BYTE_ORDER__
* Checking for __GNUC__ is not sufficient to determine if builtins are available.
* Add makefile fragment for 32-bit PowerPC on Mac OSX build, and ignore the build directories.
* Add comment describing use of __BIG/LITTLE_ENDIAN__ definition
Reformat and make use of PTRMASK & swapx() as appropriate.
It's likely that nnewframe() could be reworked to avoid needing
to unconditionally swapx() the result and, like native_newframe()
return the appropriate value as the result.
* Switch from sgtty over to termios. All of the various
separate values that were copied individually before
can now be done at once.
* Fix compilation error with missing `&`.
* Fix compilation error with missing return value.
I haven't tested that this works as I don't know how to do that,
but at least it compiles now.
* `LOGINT` is only useful when `MAIKO_HANDLE_CONSOLE_MESSAGES`
is set.
* Only define some variables if `MAIKO_HANDLE_CONSOLE_MESSAGES`
is set. Flag them as static.
* Remove setting `LOGINT` from the build system as it isn't
needed because we aren't handling console messages.
Rather than having to specify or omit -DBYTESWAP in the Makefile
fragment for each system we can detect whether the system requires
byte swapping based on the __BYTE_ORDER__ C preprocessor definition.
Update CMakeLists.txt to account for this as well.
This was a machine running SunOS 4, which we no longer support.
It had an odd display controller and a compiler with issues that
required workarounds. Those compiler issues aren't an issue in
today's world, so we don't need to keep the workarounds present
for reference.
It had a bit of inline assembly, but that is still present in
other files for other platforms.
The LowerRightX and LowerRightY were calculated as the X and Y coordinates of the
pixel to the right and below the last visible pixel, but are compared with the
last actually visible pixel in the source. They need an extra -1 offset to correct.
Add comments to explain what's going on. Fix the signature of the function to reflect
that the "dummy" passed for the display region is a pointer not an integer.
Some versions of "make" do not predefine make variable RM (looking at you, FreeBSD)
so if it has NOT been defined we define it as "rm -f"
Also, update the cleanup target to use $(RM) rather than refering directly to "rm".
This was only used in commented out code, which is now removed
as well. In that code, it was used to set the function to `GXcopy`,
but it would already have been that as that's the only thing
we set function to.
This also lets us remove the `gcv` code in `xcursor.c`, since
we no longer need those values there.
`EXTA` and `PENDIN` are not POSIX, so let's not use them.
Make notes that the baud rate constant mapping comes from DLTTY
and add comments explaining the holes.
We no longer build a separate `maiko` library that gets linked
into `ldex`. It was the only thing linking it, so now we just
build those files as part of `ldex`.
We only build `ldex` when X11 is requested (which it is by default).
If we add a new display implementation, this structure will support
that by adding a new `ldewhatever` and it will build a new binary
that the `lde` launcher can be updated to support.
We no longer need to run a separate peephole optimization pass over the
compiler generated or hand-coded assembler for SunOS3 and SunOS4 on 68K or SPARC
We remove the preprocessor symbols and code controlled by them
SUN4_OS4_IL
SUN3_OS3_IL
SUN3_OS4_IL
and SUN3_OS3_OR_OS4_IL
This removes a bit of the debug info printing, but other than
that, is pretty close to what it was before.
We also now build it in both the make and cmake build systems.
This code has not worked for a long time. Most systems now maintain
the password entries so that a password is not accessible through the
getpwent() interface. The SUBR that calls this interface may be
removed at a future time.
In the old code (prior to b234064d), this was:
```
LispReadFds &= ~(1 << LispWindowFd);
```
This was inadvertently converted to `FD_SET`, but should have
been `FD_CLR`.
