Make sure that c89 conversion doesn't produce LL or uLL postfix, since that isn't c89 at all 2019-11-14 14:18:45 +01:00

add COMPILE_LTO to test link time optimization 
the library performs best with lto since many small functions
can be inlined across objects.

apply a series of simplifications 
* this is the final commit of a series of simplifications,
  containing only the regenerated files and the explanation in the
  commit message

* This is in preparation of the size_t change/a potential representation change to use
  full width as in tfm, if a (partial?) merge with tfm is desired.
  These changes have their own merits however.

* Remove obfuscating tmpx digit pointers (fewer variables, it is more obvious what is
  being manipulated)

* Reduce scope of variables where possible

* Stricter error handling/checking (for example handling in karatsuba
  was broken)

* In some cases the result was written even in the case of an error
  (e.g. s_mp_is_divisible). This will hide bugs, since the user should
  check the return value (enforced by MP_WUR). Furthermore if the user
  accesses the non-initialized result, valgrind will complain for
  example. Global static analysis like coverity will also detect the issue.
  Therefore this improves the status quo.

* Introduce generic, private MP_EXCH macro which can be used to swap values.

* Introduce s_mp_copy_digs/s_mp_zero_digs/s_mp_zero_buf

* Some control flow simplifications, e.g, loops instead of goto

* Renamings of variables/labels for consistency

* Renamings of mul/sqr functions for more consistency, e.g., comba
  instead of fast suffix

* I didn't read through some very complex functions.
  They are so complex, I am too afraid and lazy to touch them.
  Maybe someone resposible wants to simplify them if possible. Hint... Hint...

deprecate mp_n_root_ex and mp_expt_d_ex 
These functions were introduced to give some timing guarantees.
However the guarantees are too weak to be useful.
The functions seem to be unused essentially by downstream users.
