Avoid shrinking stacks to often 2020-10-12T15:29:09+00:00 Roberto Ierusalimschy roberto@inf.puc-rio.br 2020-10-06T16:37:41+00:00 urn:sha1:9ecd446141f572252a57cb33d2bba6aa00d96a55 Shrink a stack only when the final stack size can be at most 2/3 the previous size with half of its entries empty. This commit also improves the clarity of 'luaD_growstack'.

This commit is almost a sketch, to test performance. There are several pending stuff: - review control of C-stack overflow and error messages; - what to do with setcstacklimit; - review comments; - review unroll of Lua calls. Fixed bug: wrong stack limit when entering a coroutine 2020-07-13T16:39:02+00:00 Roberto Ierusalimschy roberto@inf.puc-rio.br 2020-07-13T16:39:02+00:00 urn:sha1:e1d8770f12542d34a3e32b825c95b93f8a341ee1 When entering a coroutine, the computation of nCcalls added 'from->nci' to correct for preallocated CallInfos, but 'nci' includes also the Callinfos already used.
