Subject: [PATCH 04/40] Re-enable support for big-endian machines
|
|
|
edb6c78 |
|
|
|
edb6c78 |
First, disable the big-endian check and fail. Then, make sure the
|
|
|
edb6c78 |
namespace gets initialized properly (NB: needed even if we are only
|
|
|
edb6c78 |
compiling/disassembling data tables).
