Yann ColletandGitHub ba12054273 Merge pull request #3669 from facebook/zeroSeq_2B 
fixed decoder behavior when nbSeqs==0 is encoded using 2 bytes
 2023-06-06 00:06:15 -04:00
Yann Collet 3732a08f5b fixed decoder behavior when nbSeqs==0 is encoded using 2 bytes 
The sequence section starts with a number, which tells how sequences are present in the section.
If this number if 0, the section automatically ends.

The number 0 can be represented using the 1 byte or the 2 bytes formats.
That's because the 2-bytes formats fully overlaps the 1 byte format.

However, when 0 is represented using the 2-bytes format,
the decoder was expecting the sequence section to continue,
and was looking for FSE tables, which is incorrect.

Fixed this behavior, in both the reference decoder and the educational behavior.

In practice, this behavior never happens,
because the encoder will always select the 1-byte format to represent 0,
since this is more efficient.

Completed the fix with a new golden sample for tests,
a clarification of the specification,
and a decoder errata paragraph.

fix a minor inefficiency in compress_superblock
 2023-06-05 15:02:55 -04:00
Yann Collet 1f83b7cfc4 fix a minor inefficiency in compress_superblock 
and in `decodecorpus`:
the specific case `nbSeq=127` can be represented using the 1-byte format.
Note that both the 1-byte and the 2-bytes formats are valid to represent this case,
so there was no "error", produced data remains valid,
it's just that the 1-byte format is more efficient.

fix #3667

Gregor Jasny 7e09f07b32 Fix Intel Xcode builds with assembly 
When forcing the source file language to `C`, Xcode enforces
the file to be compiled as `C` by appending `-x c` to the
compiler command line.

For now try to limit the damage and only enforce the language
if the ASM and C compilers differ.

Reproducer (CMake `3.26.4`, Xcode `14.3`):
```
cmake -S build/cmake -B _b -GXcode -DCMAKE_OSX_ARCHITECTURES=x86_64
cmake --build _b
```

Fix: #3622

Yann Collet 94a2f2791f changed LLU suffix into ULL for Visual 2012 and lower
