|/ / | | | | | | | | | | | | | | | | | | In some contexts, *cough*like at facebook*cough*, dynamic linking is used in contexts which aren't truly dynamic. That is, the guarantee is maintained that a program will only ever execute against the library version it was compiled to interact with. For those situations, introduce a compile-time flag that overrides hiding these unstable APIs in shared objects.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Pattern analysis (currently limited to long ranges of identical bytes) is actually detrimental to performance when `nbSearches` is low. Reason is : `nbSearches` provides a built-in protection for these cases. The problem with patterns is that they dramatically increase the number of candidates to visit. But with a low nbSearches, the match finder just aborts early. In such cases, pattern analysis adds some complexity without reducing total nb of candidates. It actually increases compression ratio a little bit, by filtering only "good" candidates, but at a measurable speed cost, so it's not a good trade-off. This patch makes pattern analysis optional. It's enabled for levels 8+ only.

|/ | | | | | | | | | | | lz4opt is only competitive vs lz4hc level 10. Below that level, it doesn't match the speed / compression effectiveness of regular hc parser. This patch propose to extend lz4opt to levels 10-12. The new level 10 tend to compress a bit better and a bit faster than previous one (mileage vary depending on file) The only downside is that `limitedDestSize` mode is now limited to max level 9 (vs 10), since it's only compatible with regular HC parser. (Note : I suspect it's possible to convert lz4opt to support it too, but haven't spent time into it).

| * removed the ip++ at the beginning of blockYann Collet2017-11-082-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | The first byte used to be skipped to avoid a infinite self-comparison. This is no longer necessary, since init() ensures that index starts at 64K. The first byte is also useless to search when each block is independent, but it's no longer the case when blocks are linked. Removing the first-byte-skip saves about 10 bytes / MB on files compressed with -BD4 (linked blocks 64Kb), which feels correct as each MB has 16 blocks of 64KB.
