* mpi: remove dubious MP_DEBUG cruft.Kaz Kylheku2020-04-221-4/+0
| | | | | | | | | | | | | The MP_DEBUG macro controls the visibility of definitions that are not used anywhere. * mpi/mpi-config.h (MP_DEBUG): Removed. * mpi/mpi.c (DIAG): Macro and surrounding section controlled by #if MP_DEBUG removed. * mpi/mpi.h (MP_IOFUNC): Definition controlled by MP_DEBUG removed.
* mpi: use integer math for radix length.Kaz Kylheku2019-04-051-4/+0
| | | | | | | | | | | | | | | | | | | | * mpi/logtab.h: Regenerated. (s_logv_2): Now table of scaled integers. (MP_LOG_SCALE): New constant. * mpi/make-logtab.txr (scale, type): New variables. Generate integer table with log2 values scaled by the scale factor, rounded up. * mpi/config.h (MP_LOGTAB): Removed. We always use the table. * mpi/mpi.c: Unconditionally include logtab.h. (LOG_V_2): Macro removed. (s_mp_outlen): Rewritten using scaled integer math. Overflow is avoided by splitting the input into a part that is an exact multiple of the scale factor, and a remaining part. Only the remaining part need be multiplied by a value from the table before dividing by the scale factor.
* mpi: smaller default precision.Kaz Kylheku2017-06-181-1/+1
| | | | * mpi/mpi-config.h (MP_DEFPREC): Change from 16 to 8.
* Big MPI whitepace and comment cleanup.Kaz Kylheku2017-06-141-32/+21
| | | | | | | | * mpi/logtab.h, mpi/mpi-config.h mpi/mpi-types.h mpi/mpi.c, mpi/mpi.h mpi/mplogic.c mpi/mplogic.h: Reformatted comments. Removed useless comments. Removed superfluous blank lines and whitespace. Added space between C keywords if, for, while, sizeof and opening parens. Removed #if 0 blocks. Tabs to spaces.
* mpi: eliminate trailing whitespace.Kaz Kylheku2016-11-141-1/+1
| | | | | | | | | * mpi/mpi-config.h: Eliminate several trailing spaces. * mpi/mpi.c: Eliminate all trailing spaces. Removed some commented-out code, and adjusted brace placement and indentation in one place. Also removed some spurious blank lines.
* Remove include guards from MPI headers.Kaz Kylheku2015-08-151-7/+0
| | | | | * mpi/mpi-config.h, mpi/mpi.h: These headers do not require include guards. They included only once.
* Bringing MPI library out of tarball into GIT.Kaz Kylheku2015-04-221-0/+85
Importing 1.8.6 upstream baseline, minus unwanted stuff.
