Matthieu Darbois 6e7616c83c Remove TODO for overflow check (#842)
The check was already done. It’s been simplified.
Reformat to get consistent style throughout the functions.

Need to cast to size_t before multiplication otherwise overflow check is useless.

Stephan Mühlstrasser 8750e183c6 Moved type OPJ_BITFIELD from openjpeg.h to opj_includes.h
OPJ_BITFIELD is used only in internal headers and must not
appear in the public openjpeg.h header.

Matthieu Darbois 9f24b078c7 Change 'restrict' define to 'OPJ_RESTRICT' (#816)
Visual Studio 2015 does not pass regression tests with `__restrict` so kept disabled for MSVC.
Need to check proper usage of OPJ_RESTRICT (if correct then there’s
probably a bug  in vc14)

Closes #661

Even Rouault 4f9abb9a45 [Win32] Use _beginthreadex instead of CreateThread() 2016-08-11 21:59:28 +02:00
Stephan Mühlstrasser 54874194a8 Unified bit-field declaration, removed tabs. 2016-07-27 10:09:54 +02:00
Stephan Mühlstrasser d2d35bf6c2 Create separate type for bit-fields.
The definition of bit-fields with type OPJ_UINT32 caused complilation errors
on IBM iSeries, because OPJ_UINT32 is defined as uint32_t, and
uint32_t is defined as unsigned long in <stdint.h>. The definition of
bit-fields with an integer type of  a specific size doesn't make sense
anyway.

Even Rouault 5fbb8b2645 Use thread-pool for T1 decoding 2016-05-25 21:02:07 +02:00
Even Rouault d4b7f03cfa Add opj_codec_set_threads() in public API and propagate resulting thread pool to tcd level
By default, only the main thread is used. If opj_codec_set_threads() is not used,
but the OPJ_NUM_THREADS environment variable is set, its value will be
used to initialize the number of threads. The value can be either an integer
number, or "ALL_CPUS". If OPJ_NUM_THREADS is set and this function is called,
this function will override the behaviour of the environment variable.

Even Rouault 107eb31531 Improve perf of opj_t1_dec_sigpass_mqc_vsc() and opj_t1_dec_refpass_mqc_vsc() with loop unrolling 2016-05-23 13:45:15 +02:00
Even Rouault 8371491a99 Better inlining of opj_t1_updateflagscolflags() w.r.t. flags_stride 2016-05-23 11:53:54 +02:00
Even Rouault 956c31d5a6 opj_t1_dec_clnpass(): remove useless test in the runlen decoding path (of the non VSC case) 2016-05-23 11:53:54 +02:00
Even Rouault 93f7f90711 opj_t1_decode_cblks(): tiny perf increase when loop unrolling 2016-05-23 11:53:53 +02:00
Even Rouault 1da397e94a Tier 1 decoding: add a colflags array
Addition flag array such that colflags[1+0] is for state of col=0,row=0..3,
colflags[1+1] for col=1, row=0..3, colflags[1+flags_stride] for col=0,row=4..7, ...
This array avoids too much cache trashing when processing by 4 vertical samples
as done in the various decoding steps.

Even Rouault 31882ad7f4 Const'ify lut arrays so they are in the read-only data section 2016-05-22 00:54:06 +02:00
Even Rouault ba1edf6cd4 Reduce number of occurrences of orient function argument
This is essentially used to shift inside the lut_ctxno_zc, which we
can precompute at the beginning of opj_t1_decode_cblk() /
opj_t1_encode_cblk()

Even Rouault 23a01dfdef Specialize decoding passes for 64x64 code blocks 2016-05-21 16:27:35 +02:00
Even Rouault d8fef96f23 Improve code generation in opj_t1_dec_clnpass()
Add a opj_t1_dec_clnpass_step_only_if_flag_not_sig_visit() method that
does the job of opj_t1_dec_clnpass_step_only() assuming the conditions
are met. And use it in opj_t1_dec_clnpass(). The compiler generates
more efficient code.

Even Rouault c539808d09 opj_t1_updateflags(): tiny optimization
We can avoid using a loop-up table with some shift arithmetics.

Julien Malik 17a0a8a195 Use lowercase for cmake commands consistenly
Inspired from https://github.com/InsightSoftwareConsortium/ITK/blob/master/Utilities/Maintenance/HowToCreateTheCMakeCaseConversion.txt
This needs vim 7.3 and fails with vim 7.4

This also fixes a number of :
- missing empty line at end of files
- useless space at end of lines

Antonin Descampe 72deb588cb Merge pull request #706 from mayeut/issue135
Fix issue 135
The fix is legal regarding the standard but I did not manage to find out if it covers a bug in opj_t2_read_packet_data or if the file is corrupted
