[fuzz] Improve fuzzer build script and docs
 2019-08-21 10:09:38 -07:00
Nick Terrell
3982935aef [fuzz] Improve fuzzer build script and docs 
* Remove the `make libFuzzer` target since it is broken and obsoleted
  by `CC=clang CXX=clang++ ./fuzz.py build all --enable-fuzzer`. The
  new `-fsanitize=fuzzer` is much better because it works with MSAN
  by default.
* Improve the `./fuzz.py gen` command by making the input type explicit
  when creating a new target.
* Update the `README` for `--enable-fuzzer`.

Fixes #1727.

37f47e51a8 fixed datagen 
to produce same content on both 32 and 64-bit platforms
by removing floating from literal table determination.

also : added checksum trace in compression control test,
so that it's easier to determine if test fails
as a consequence of compressing a different sample.

* [ldm] Fix bug in overflow correction with large job size

* [zstdmt] Respect ZSTDMT_JOBSIZE_MAX (1G in 64-bit mode)

* [test] Add test that exposes the bug

Sadly the test fails on our CI because it uses too much memory, so
I had to comment it out.
