tg df8681e880 fixup by regenerating with new eawparse which matches what I submitted to 
https://sourceware.org/bugzilla/show_bug.cgi?id=21750 even if only FF00
actually changed due to the algorithms in use

mirabilos 7fb9d283c5 Merge mksh CVS HEAD 2017-04-02 16:32:16 +02:00
tg 7529e350cf small character classes overhaul: 
• make fast character classes even faster by removing the C_SUBOP2 hack
  in favour of a separate seldom-used ksh_issubop2 macro (which also
  makes ctype() side-effect-safe) which is a slower class (no change there)
• optimise cases of ksh_isalphx followed by a ksh_isalnux loop
  (used parsing variable names)
• remove a misleading comment in initctypes() about \0 from pdksh
• rename C_ALPHA to C_ALPHX to make it more clear the underscore is included
• sprinkle a few ord() in there
• add new ksh_isalpha() which tests for [A-Za-z] (slow character class)
• there is no '_:\' drive on OS/2 (which inspired the whole changeset)

tg c3e794c4d0 rework string pooling; disable our own (rely on compiler’s)… 
• if HAVE_STRING_POOLING is set to 1
• if HAVE_STRING_POOLING is set to 2 and not GCC < 4 is used
• if HAVE_STRING_POOLING is not set to 0 and LLVM or GCC >= 4 is used

Closes: LP#1580348

tg 75a4809a3a fix remaining signed int nonsense I am aware of 2013-04-26 19:10:58 +00:00
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 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 0f417614dd ugh, signed >> on negative values is implementation-defined

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
