Changes:
* The compiler has been improved to generate overflow checking code
by default. The generation of overflow checking code can be
switched off with the option -so.
* The exception OVERFLOW_ERROR has been introduced. It is raised by
the interpreter and by compiled programs when an integer overflow
occurs.
* A paragraph about integer overflow and the installation of Seed7
has been added to the FAQ.
* The chapter about exceptions in the manual has been improved.
* The program chkovf.sd7, which checks the recogition of integer
overflows, has been added.
* Checks for +, -, *, rem, mod, <<, +:=, -:=, *:=, succ, pred, incr
and decr have been added to chkint.sd7.
* Checks for the lpad operator have been added to chkstr.sd7.
* The compiler option -r has been replace by the option -sr.
* The program calc7.sd7 has been improved to report MEMORY_ERROR and
OVERFLOW_ERROR.
* The library make.s7i has been improved such that make7.sd7 accepts
echo (and echo.) statements without parameters.
* The function eof has been defined for the type tlsFile in tls.s7i.
* The function gets in tls.s7i has been improved.
* The function getHttp in gethttp.s7i has been improved to avoid an
endless loop when eof has been reached.
* The function memcpy_from_strelem has been added to striutl.c. This
function uses loop unrolling inspired by Duff's device and a trick
with a binary or (|=) to check for allowed values.
* The functions filWrite, socWrite and bstParse have been changed
to use memcpy_from_strelem. The reduction in runtime has been
measured with gcc and valgrind. The runtime of filWrite, socWrite
and bstParse has been reduced to 53%, 61% and 56% respectively.
* Documentation comments have been added to integer.s7i, bin32.s7i,
intlib.c and striutl.c.
* The compiler has been improved to generate overflow checking code
for *, <<, >>, *:=, <<:= and >>:= .
* The generation of overflow checking code for the operators rem and
mod has been improved.
* Checks for overflow, division by zero, numeric error and index out
of bounds in compiled programs now use the macros ovfChk, divChk,
numChk and idxChk. This macros inform the C compiler about the
unlikeliness of an exception.
* The function fltIPow has been improved to avoid a signed integer
overflow, when the exponent is the most negative integer.
* The primitive actions INT_ULSHIFT and INT_ULSHIFT_ASSIGN have been
added and supported in interpreter and compiler.
* A version of the function uint_rand, which uses 128-bit integers,
has been added to int_rtl.c.
* The function raise_error3 in runerr.c has been renamed to
interprRaiseError.
* The configuration values INT128TYPE, UINT128TYPE and MACRO_DEFS
have been added to cc_conf.s7i. The configuration value
SIGILL_ON_OVERFLOW has been replaced with OVERFLOW_SIGNAL.
* The functions constValueIsEqual, checkRangeFromZero,
process_const_int_lshift, process_const_int_lshift_assign,
process_const_int_rshift_assign, process_const_int_mult,
process_const_int_mult_assign, process_const_int_ulshift_assign,
process_const_int_ulshift and process_const_int_urshift_assign
have been added to int_act.s7i.
* The function intExpr in chkbig.sd7, chkexc.sd7, chkint.sd7 and
chkstr.sd7 has been changed to make sure that the C compiler
cannot evaluate it at compile time.
* The runtime of the functions str_lpad, strLpad and strLpadTemp has
been improved.
