Even Rouault 9a9b06911e opj_t1_dec_sigpass_raw/opj_t1_dec_refpass_raw: harmonize style with mqc methods 2017-06-02 19:22:15 +02:00
Even Rouault 532243f1fd MQC/RAW decoder: use an artificial 0xFF 0xFF terminating marker. 
This saves comparing the current pointer with the end of buffer pointer.
This results at least in tiny speed improvement for raw decoding, and
smaller code size for MQC as well.

This kills the remains of the raw.h/.c files that were only used for
decoding. Encoding using the mqc structure already.

Even Rouault dde6cbabc0 Simplify VSC handling: instead of masking out bits when reading the 4th row. 
Do not set them when updating flags of the 1st row
 2017-06-02 18:23:38 +02:00
Even Rouault 3d9940a35b Force inlining of mqc decoding and pass steps through heavy use of macros, so as to get better register allocation 2017-06-02 18:23:20 +02:00

Even Rouault a0861855c1 T1: remove use of neghalf variable. It is useless since bpno is always > 0 2017-06-02 18:22:21 +02:00
Even Rouault 10410fe72e T1: avoid pointer indirection for mqc and raw members of opj_t1_t 2017-06-02 18:21:54 +02:00
Even Rouault a5003787ff T1: remove flags_stride variable from opj_t1_t 2017-06-02 18:21:39 +02:00

Even Rouault 4068363ff5 T1: fix VSC mode in encoder 2017-05-23 16:16:32 +02:00
Even Rouault cd12414c6b T1: use more compact flags to optimize cache usage in encoder passes. (#172) 
Ported from Carl Hetherington work (actually through Matthieu Darbois's port
on top of OpenJPEG 2.1.0)

Can reduce total encoding time by 10-15%

WARNING: VSC mode is not implemented, and so is a temporary regression
that must be fixed.

Matthieu Darbois f88c9974e2 Flags in T1 shall be unsigned (#840) 
This will remove some conversion warnings
 2016-09-14 23:46:46 +02:00
Matthieu Darbois 0954bc11e3 Fix some warnings (#838)

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 7d3c7a345f Be robust to failed allocations of job structures 2016-05-26 23:51:32 +02:00
Even Rouault 5fbb8b2645 Use thread-pool for T1 decoding 2016-05-25 21:02:07 +02:00
Even Rouault 7092f7ea11 Fix MSVC210 build issue (use of C99 declaration after statement) introduced in ba1edf6cd4 2016-05-23 16:00:28 +02:00
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.
 2016-05-23 11:53:53 +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()
 2016-05-22 00:50:34 +02:00
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.
 2016-05-21 15:52:02 +02:00
Even Rouault c539808d09 opj_t1_updateflags(): tiny optimization 
We can avoid using a loop-up table with some shift arithmetics.

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

Matthieu Darbois e6881e7527 Fix negative shift left reported by UBSan (#758) 
Follow-up of #757

This shall have no performance impact on 2’s complement machine where
the compiler replaces the multiplication by power of two (constant) by
a left shift.
Verified at least on MacOS Xcode 7.3, same assembly generated after fix.
