This is the Brotli data compression library from
|
||
|
|
https://github.com/google/brotli.
|
||
|
|
|
||
|
|
Currently, we import only the Brotli decoder (the /dec/ subdirectory), not the
|
||
|
|
encoder (/enc/ subdirectory).
|
||
|
|
|
||
|
|
Upstream code can be viewed at
|
||
|
|
https://github.com/google/brotli/tree/master/dec
|
||
|
|
|
||
|
|
and cloned by
|
||
|
|
git clone https://github.com/google/brotli
|
||
|
|
|
||
|
|
The in-tree copy is updated by running
|
||
|
|
sh update.sh
|
||
|
|
from within the modules/brotli directory.
|
||
|
|
|
||
|
|
Current version: [commit 933bb9bd800c8f5f7f6a02382d33c902a98ef73a].
|
||
|
|
|
||
|
|
this trivial patch is added to preserve no-warnings behavior in code
|
||
|
|
that includes the brotli interface. future imports are expected to
|
||
|
|
have an equivalent change made upstream already.

This patch fixes a use-before declare error on big endian platforms
|

in bit_reader.h. Upstream has already fixed this error by re-arranging
|

|
|
some functions in the file.
