92370ec355 shave off 12 bytes (with fixed gcc) by making the definitions more legible

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

‣ not like oksh did, but using mksh’s built-in features
• handle suggested __pure additions
• revert cid 1004F7F096867C83CF0
  ‣ always use our wcwidth code

• fix a couple of gcc-snapshot and clang/scan-build warnings

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…)

0f417614dd ugh, signed >> on negative values is implementation-defined 
(but, at least, not undefined, and usually right; regress-test for it)

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

9646c98356 I give up on writing (1 << 31) in any form. 
Now we just use 0x80000000UL and cast that to mksh_uari_t and,
if required, that to mksh_ari_t afterwards.

cf75e7b6ce couple of minor/cosmetic fixes from RT’s compile farm: 
• promote SCO OpenServer and UnixWare to !oswarn
• omit trying -O2/-O on OpenServer 5 and USL C
• cast mksh_ari_t to int, mksh_uari_t to unsigned int for printf
• skip ulimit-1 on syllable (which is still too broken)
• write ((mksh_ari_t)-2147483648) ipv UB ((mksh_ari_t)1 << 31)
  and add a comment that that is actually meant
• rewrite functions returning !void ending in NOTREACHED
  so they’ve got a jump target returning an error at the
  end, to aid older compilers and just to be safe
• cast struct stat.st_size to off_t or size_t explicitly when needed
• shorten struct env by two bytes and an alignment, at least

also, optimise control flow and fix more paren matching cases

7ec1ae3771 followup for cid 1004EE408E1382C1752 and 1004EE40DDD498FBB0D:

smoked/were brain-dead or if we don’t actually need the manual check

a77bbf6123 HP aCC tells me I'm using "const" twice, and /usr/ccs/bin/cc even
