2016-05-25Use thread-pool for T1 decodingEven Rouault
2016-05-25Add opj_codec_set_threads() in public API and propagate resulting thread ↵Even Rouault
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.

2016-05-23Improve perf of opj_t1_dec_sigpass_mqc_vsc() and ↵Even Rouault
opj_t1_dec_refpass_mqc_vsc() with loop unrolling
2016-05-23Better inlining of opj_t1_updateflagscolflags() w.r.t. flags_strideEven Rouault
2016-05-23opj_t1_dec_clnpass(): remove useless test in the runlen decoding path (of ↵Even Rouault
the non VSC case)
2016-05-23opj_t1_decode_cblks(): tiny perf increase when loop unrollingEven Rouault
2016-05-23Tier 1 decoding: add a colflags arrayEven Rouault
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.
2016-05-22Const'ify lut arrays so they are in the read-only data sectionEven Rouault
2016-05-22Reduce number of occurrences of orient function argumentEven Rouault
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()
2016-05-21Specialize decoding passes for 64x64 code blocksEven Rouault
2016-05-21Improve code generation in opj_t1_dec_clnpass()Even Rouault
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.
2016-05-21opj_t1_updateflags(): tiny optimizationEven Rouault
We can avoid using a loop-up table with some shift arithmetics.
2016-05-21Move some MQC functions into a header for speedKal Conley
Allow these hot functions to be inlined. This boosts decode performance by ~10%.

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

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

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.
