  • 104d249ffb in return hook, 'top' must be corrected only if smaller than 'ci->top'. (It may be larger when returning multiple values, and then it must be larger to preserve that stack slice.) Roberto Ierusalimschy 2018-02-17 16:22:00 -0200

  • 86431a2f1c new opcodes BANDK/BORK/BXORK. (They do not use immediate operands because, too often, masks in bitwise operations are integers larger than one byte.) Roberto Ierusalimschy 2017-12-13 16:32:09 -0200
  • 36cf8f3a3c Code should not change the stack level after the initialization of a string buffer. Roberto Ierusalimschy 2017-12-13 10:51:42 -0200
  • 725c15a4ca when shrinking stack, always shrinks the CI list. (Stack overflow is not corelated to CI overflow anymore.) Roberto Ierusalimschy 2017-12-12 09:57:30 -0200
  • b077b20206 back to reallocation when resizing the string table. (Not a good idea to explicitly allocate new memory when shrinking something.) Roberto Ierusalimschy 2017-12-12 09:52:35 -0200
  • 3cf340f676 allows memory-allocation errors when shrinking blocks Roberto Ierusalimschy 2017-12-11 16:55:31 -0200

  • c5ebed7399 'luaM_shrinkvector' raises an error if it cannot shrink the block (several parts of Lua use array size in protos as proxies for number of valid elements) Roberto Ierusalimschy 2017-12-11 10:27:48 -0200
  • e663a24ab0 more freedom in handling memory-allocation errors (not all allocations automatically raise an error), which allows fixing a bug when resizing a table. Roberto Ierusalimschy 2017-12-08 15:28:25 -0200

  • 9fa1baf6de opcodes for order and shift can use several metamethods, so it is better to use a generic description + metamethod names in some error messages shown without '__' prefix Roberto Ierusalimschy 2017-12-07 13:44:10 -0200
  • 49dfaf7447 avoid using one function for different tasks (malloc, free, etc.) Roberto Ierusalimschy 2017-12-06 16:36:31 -0200
