45/* All functions and global variables declared anywhere should use
46 one of the following attributes:
47
48 RPY_EXPORTED: the symbol is exported out of libpypy-c.so.
49
50 RPY_EXTERN: the symbol is not exported out of libpypy-c.so, but
51 otherwise works like 'extern' by being available to
52 other C sources.
53
54 static: as usual, this means the symbol is local to this C file.
55
56 Don't use _RPY_HIDDEN directly. For tests involving building a custom
57 .so, translator/tool/cbuild.py overrides RPY_EXTERN so that it becomes
58 equal to RPY_EXPORTED.
59
60 Any function or global variable declared with no attribute at all is
61 a bug; please report or fix it.
