From the V6 C compiler source:
/*
* The hash table locations of the keywords
* are marked; if an identifier hashes to one of
* these locations, it is looked up in in the keyword
* table first.
*/
for (ip=kwtab; (sp = ip->kwname); ip++) {
i = 0;
while (*sp)
i =+ *sp++;
hshtab[i%hshsiz].hflag = FKEYW;
}
Note also that in that version of the compiler, MOS
(member of structure) names were global and could be
used with any pointer regardless of type.
https://github.com/mortdeus/legacy-cc/blob/master/last1120c/c00.c
This makes it difficult to build the original V6 c compiler using
a modern compiler :-)
