tg 1df3efdb86 another intermediate step/commit to get arithmetics right:
do the correct operations for comparisons (just keep using the
signed/unsigned switch from bivui for them), division (by working
on absolutes and adding the sign at the end), modulo (stupidly by
divising in signed, multiplying and subtracting, to get the sign
of the result right)

also adds rotation

XXX to check: do we need to AND before assigning the result in division?

tg 5a8d3175cb just rcsid-sync oksh; their change was to add /* XXX 2038 */ comment
to $SECONDS (tbh, in 2038 we’ll have more problems than just that,
which is why 64-bit arithmetics, or unlimited-precision ones, are
on the “plans” list)

tg 1a21176cac Tonnerre Lombard’s contribution:
[17:27:44] Tonnerre: csh: alias doch sudo \!-1 bash: alias doch='sudo $(history -p !-1)' zsh: alias doch='sudo $(fc -ln -1)'
[17:28:03] mirabilos: ?
[17:28:34] Tonnerre: Na ganz einfach:
[17:28:36] Tonnerre: % ls /root
[17:28:39] Tonnerre: ls: cannot open directory /root: Permission denied
[17:28:42] Tonnerre: % doch
[17:28:45] Tonnerre: [sudo] password for tonnerre:
[17:28:49] Tonnerre: anaconda-ks.cfg  cgminer-1.6.2-1.rf.src.rpm  rpmbuild  upgrade.log  upgrade.log.syslog
[17:28:53] Tonnerre: %

This is one of two mksh variants; the other uses a tmpfile:
alias doch='sudo mksh -c "${ fc -ln -1;}"'

Both quote correctly, unlike the above.

Maybe use $MKSH instead? (Quoted or unquoted? Hm. Probably quoted.)
Input on that welcome…

tg 7cce9de0bc one can’t cast an unsigned int to a signed int portably either, if the value
is larger than the positive range of the latter (implementation-defined), so
avoid them in all explicit cases and rearrange stuff and check for it

(I’m gonna have to revise lots more code…)

tg e1a4c3ed28 do use val.u on the RHS of a shift 2013-04-01 01:29:47 +00:00
tg 0f417614dd ugh, signed >> on negative values is implementation-defined
(but, at least, not undefined, and usually right; regress-test for it)

tg d96c733069 looks like multiplication is also the same between signed and unsigned 2013-04-01 01:02:09 +00:00
tg 6a745a01fa begin using unsigned arithmetics internally as much as possible
(i.e. where signedness doesn’t matter, given -fwrapv) and note
where there’s work to do; note future improvements and additions;
optimise a little

mostly untested

tg e141cab1ac revert cid 10050DD0C8519194AE9 and 100511FC81525949AF7
AT&T SVR4 broke 'cc -c -o foo.o foo.c' totally

switch to an alternative method of finding out the prototypes
provided in IRC by dalias (thanks); RT says this fixes his
issues on SVR4 – let’s just ignore the ominous message from
cid 1004713D70A5362BACF about needing to be a compile-time
check unless something else pops up, I can’t think of something
that isn’t already covered

tg e21a2166f7 use a different approach to the $"…" problem:
take the states that may open a string, only permit them by virtue of
moving the code out of Subst: to handle $+" and $+' at all; then add
S[Q]BRACE to that

side benefits:
• clearer, cleaner code flow
• smaller code
• better “business logic” ☺
• defuses one heavy use of duff’s device a bit
