Roberto Ierusalimschy de2caf7ee4 Bit-library file removed from the project (as it was deprecated) 
This commit only removed the file 'lbitlib.c' from the project; the
makefile already was not using it.

Roberto Ierusalimschy b08c9079c5 Opcode names moved to a new header file 
The array with the names of the opcodes was moved to a header file
('lopnames.h'), as it is not used by the Lua kernel. Files that need
that array ('luac.c' and 'ltests.c') include the header file to get
a private (static) copy.
 2018-07-09 12:50:51 -03:00
Roberto Ierusalimschy 06e08c6d05 Fixed bug in OP_IDIVI 
Opocode was using 'luai_numdiv' (float division) instead of
'luai_numidiv' (integer division).

Roberto Ierusalimschy a314409dba in generational mode, an emergency collection can turn any object black 
during any memory allocation +
'luaT_getvarargs' may reallocate the stack, and therefore the top must
be correct.
