instead of HOST (and allow it to be set from the env), use $(MAKE)
instead of make to allow using the jobserver properly, and remove the
dash from commands where we do care about the return code (or inhibit
errors the usual way: rm -f instead of -rm)
Enaling link time optimizations for kpdfview binary and crengine library
causes another slight performance increase --- almost negligible (1-2ms
per page) but still noticeable by precise measurements.
Thanks to NiLuJe who pointed out that our generic -march=armv6 can be
replaced (for K2/K3/DX/DXG) with a more specific optimization:
-march=armv6j -mtune=arm1136jf-s -mfpu=vfp. This I have now done and
also passed ARM_CFLAGS value to CXXFLAGS which is then passed to
crengine build. Tested, works fine. The performance improvement is
negligible (a few ms per page, but seems to be consistently better, i.e.
not just plus/minus fluctuations).
Thanks to NiLuJe who pointed out that we are building mupdf in debug
mode. Switching to "release" build reduced the size of the kpdfview
binary and did not cause any performance degradation (but no noticeable
improvement either --- the page handling times seem to be exactly the
same, i.e. fluctuating a couple of ms in both directions).
This is a better version of the previous commit, which:
a) makes the code more readable
b) disallows rcountmax values like "6.05", i.e. restricts to integers
only.
1. ATM, the footers in selectmenu.lua & helppage.lua are left-adjusted,
these also contain the prompt for users how to call help
(selectmenu.lua) and how to go back (helppage.lua). By minor correction
to function DrawFooter() in filechooser.lua, one may readily make the
rest footers to look in a similar way.
2. When writing the code of inputbox.lua, I (NuPogodi) left the wrong
command to delete the 1st entry in the math function list
(called in calculator mode by pressing Alt-M).
The printf() about the number of links on a page is very useful, but
only for debugging. As other instances of debugging printf() in djvu.c
and pdf.c are commented out, it seemed consistent to do the same with
this one.
1. Remove unused "-lsdtc++" from the compilation stage as no linking is
done then.
2. Add our standard CFLAGS to the compilation of cre.cpp which brings in
-O3 -march=armv6 which enables optimizations.
It seemed strange that we compile a cpp file with gcc (as opposed to
g++), but I left it as is for now.
