George Koehler 84f65f7ce3 Raise _XOPEN_SOURCE from 500 to 700 
In OpenBSD, _XOPEN_SOURCE 500 forces _POSIX_C_SOURCE down to 199506,
which hides the declarations of openat() and fdopendir() and causes
compiler warnings.

Don't set _POSIX_C_SOURCE, because _XOPEN_SOURCE may set
_POSIX_C_SOURCE to a different value.

George Koehler cdbff0dd1c Include <fcntl.h> or <unistd.h> 
This silences some clang warnings of implicit declarations of
functions.  The `register int` silences a warning of implicit int.

George Koehler dd328215d8 Use %zu to print size_t count 
This silences a compiler warning.

George Koehler f8cbe04447 Include <unistd.h> for lseek() 
This unbreaks my build in OpenBSD.  The old `long lseek()` conflicts
with `off_t lseek()` in OpenBSD headers, because long and off_t are
different types.  Commit b4df26e caused "system.h" to include some
headers where OpenBSD declares lseek().

Manuals for lseek() say to #include <unistd.h>.  Do so to be portable
to systems where other headers don't declare lseek().

i80: Better peephole optimiser rules
 2019-03-11 17:00:12 +01:00
David Given c59eae1429 Don't buffer overflow when trying to process source bytes with the high bit 
set.

David Given 88fd7b3cdc Add a 'kill' pseudoinstruction to the 8080 assembler, which marks when the code 
generator is finished with a register; use this to create some more effective
peephole optimiser rules.
