87968517f9 fixed decoding block checksum in lz4frame 2017-10-04 15:24:08 -07:00

f6b31bf0d0 fix #404 
static analyzer `cppcheck` complains about a shift-by-32 on a 32 bits value,
which is an undefined behavior.
However, the flagged code path is never triggered in 32-bits mode,
(actually, it's not even generated if DCE kicks in),
the shift-by-32 is necessarily performed on a 64-bits value.

While it doesn't change anything regarding lz4 code generation, for both 32 and 64 bits mode,
(can be checked by md5sum on the generated binary),
the shift has been rewritten in a way which should please this static analyzer,
since it now pretends to shift by 16 on 32-bits cpu (note : it doesn't matter since the code will not even be generated in this case).

Note : this is a blind fix, the new code has not been tested with cppcheck, because cppcheck only works on Windows.
Other static analyzer, such as scan-build, do not trigger this false positive.

252ce14fd2 Don't use C++11 deprecation attribute with clang 
Clang doesn't accept a C++11 attribute following `LZ4LIB_API`.
Use the GNU attribute instead.

01cdbfb5fe lz4c legacy commands are now enabled at runtime based on link/binary name "lz4c" 
instead of selected at compilation time depending on a macro.
This design makes it possible to have a single binary which supports both modes.

An advantageous side effect is that when doing `make; make install`
no additional binary is created during `make install`
(it used to create `lz4c`, because `make` would only build `lz4`)
