380466e0d3 Allow inlining of function TruncateParam 
It is only used locally in intproto.cpp, so defining it before the first
use and adding the static attribute allows the compiler to inline it.

Fix intsimdmatrixneon.cpp stack corruption.
 2020-05-27 16:31:23 +02:00
Robin Watts
6fec69de1a Fix intsimdmatrixneon.cpp stack corruption. 
The intsimdmatrix mechanism ensures that inputs would be
resized so that we'd only ever get "whole blocks" of data.
I'd assumed that that meant the same thing for scales/outputs
too, but this appears not to to be the case, as we can get
called (sometimes) with num_out % 8 == 7.

Possibly we could benefit from resizing those matrices so
that special cases in this innermost loop are not actually
required, but unless and until that is done, let's fix the
inner loop.

Add NEON SIMD code

f79e52a7cc NEON SIMD code. 
In tests on my pi3b+, a release build of my ghostscript integration
takes 2 minutes 27 seconds to render a PDF and OCR it with the
vanilla sources. With this NEON coded added the time drops to 37
seconds.

I have not tested the configure/Makefile changes as I'm not using
them.

27d513462c Avoid using PACKAGE_VERSION in favour of TESSERACT_VERSION_STR. 
This means the sources compile perfectly in the absence of
config_auto.h/HAVE_CONFIG_H as they were intended to do.

TESSERACT_VERSION_STR is set to be precisely PACKAGE_VERSION
by autoconf, so there are no actual changes in compiled code.

39f7fb4a1a Allow line images with larger width (depending on height) 
Training with normalized line images higher than 36 px also results in larger widths.
The limit should therefore depend on the height used for the normalization.
