UNALIGNED_FETCH_OK shouldn't be set for an entire OS, but
based on the CPU architecture.
Some ARM systems don't allow unaligned reads. x86 and x86_64
do, so update how we configure this.
In the SunOS 4 days, the system cc apparently couldn't compile
the lp* files, so there was an arrangement to use an `ANSICC`,
which was just `gcc`, to build those files.
We no longer have this issue.
By adding `0.0` and not `0.0f` and by calling `fmod()` rather than
`fmodf()`, we were unintentionally coercing the value from a
`float` to a `double`.
This resulted in x86_64 assembler like this:
```
cvtss2sd %xmm0,%xmm0
cvtss2sd %xmm1,%xmm1
callq 403340 <fmod@plt>
cvtsd2ss %xmm0,%xmm0
```
which is now:
```
callq 403360 <fmodf@plt>
```
And for the `N_OP_equal` change:
```
cvtss2sd %xmm0,%xmm0
xorpd %xmm2,%xmm2
addsd %xmm2,%xmm0
cvtss2sd %xmm1,%xmm1
addsd %xmm2,%xmm1
xor %ecx,%ecx
ucomisd %xmm1,%xmm0
```
is now:
```
xorps %xmm2,%xmm2
addss %xmm2,%xmm0
addss %xmm2,%xmm1
xor %ecx,%ecx
ucomiss %xmm1,%xmm0
```
(Note `ss` rather than `sd`, along with the missing `cvtss2sd` calls.)
This wasn't actually hooked up any more, so it was pretty much
all dead code. The handling of this in the command line options
is gone.
In `bin/makefile-tail`, `DEVFILES` and `LIBFILES` became identical, so
`DEVFILES` went away.
* Delete code related to NATIVETRAN feature.
This was obsolete work that had been done for generating
native code from the bytecode.
ClosesInterlisp/medley#89.
* Remove unused SaveD6.
Previously, we were building as C89 and the new code required
the C99 flag on Solaris with Sun Studio. Now that we build as
C99, this should work now and we can remove the special case
code.
The predefined cursors (image and mask) are better represented
as arrays of const uint8_t rather than char. Likewise for the
window icon. Track this change in the functions that take the
image and mask as arguments, casting only when we get to the
X library functions that take char*.
* Bit of cleanup for Lisp_Xinitialized.
* Remove the `extern` from `xcursor.c`, where it was not used.
* Move the definition from `main.c` to `xinit.c` as it is
the only file using it.
* Use `stdbool.h` for it rather than an `int` with custom `TRUE`
and `FALSE` values.
* Add some asserts with Lisp_Xinitialized.
Add standardized options for Oracle Developer Studio C compiler (aka SunPro C)
Using -funsigned-char causes the Oracle Developer Studio C compiler typedefs for
int8_t to become unsigned (uint8_t) rather than signed, with no warning or
other indication that this has happened.
The definition of a function was ifdef'd out, making it seem
like perhaps there was an assembly implementation, but there
isn't. That platform support is dead weight also at this point,
so removing this because it isn't something that will come back
is fine.
Homebrew on the macOS build machines for GitHub Actions was
updated to version 2.7 and that deprecated the `brew cask install`
syntax in favor of `brew install --cask`, so we need to update
here.
The announcement for the GitHub change is:
https://github.com/actions/virtual-environments/issues/2415
Like the renaming of NOFORN, this gets rid of some double
negatives. It also removes some patterns where we had:
```
#ifdef NOETHER
#else
...
#endif
```
and replaces them with:
```
#ifdef MAIKO_ENABLE_ETHERNET
...
#endif
```
This lets us get rid of double-negatives, which are confusing,
and starts a naming scheme that is easier to see when something
is a Maiko flag versus something else.
This also adds a bit to the `-info` output to say which OS and CPU
are being targeted.
This can be used in subsequent commits to drive whether or not
we need `BYTESWAP` and whether or not unaligned memory access
is okay.
We'll be able to remove per-platform defines from all of the
makefiles and cmake.
This might have been necessary before where we had bits of code
that were still `#ifdef LINUX`, but that's mostly gone now, so
this should no longer be required.
