More uses of macros 'likely'/'unlikely' (renamed to
'l_likely'/'l_unlikely'), both in range (extended to the
libraries) and in scope (extended to hooks, stack growth).
Several details about 5.4.0 rc12020-04-23T17:48:15+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2020-04-23T17:48:15+00:00urn:sha1:0ddc0f47bd2a03678e1afbc384550aecb55a318f
Corrected several small details: added 'const', adjusts in tabs x
spaces, removed unused #includes and #defines, misspellings, etc.
Using an enumeration for float->integer coercion modes2019-12-05T17:14:29+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2019-12-05T17:14:29+00:00urn:sha1:d30569c06407529cc6e99f4a35ae5f9bfe6fa940New macros for arithmetic/bitwise operations in 'luaV_execute'2018-11-05T18:10:42+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2018-11-05T18:10:42+00:00urn:sha1:5e76a4fd313a8690d300085c4e8fcb9dca50c01a
The repetitive code of the arithmetic and bitwise operators in
the main iterpreter loop was moved to appropriate macros.
(As a detail, the function 'luaV_div' was renamed 'luaV_idiv',
as it does an "integer division" (floor division).
Corrections in the implementation of '%' for floats.2018-08-28T15:36:58+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2018-08-28T15:36:58+00:00urn:sha1:5382a22e0eea878339c504b2a9a3b36bcd839fcc
The multiplication (m*b) used to test whether 'm' is non-zero and
'm' and 'b' have different signs can underflow for very small numbers,
giving a wrong result. The use of explicit comparisons solves this
problem. This commit also adds several new tests for '%' (both for
floats and for integers) to exercise more corner cases, such as
very large and very small values.
Removed extra information from RCS keyword strings2018-08-23T17:26:12+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2018-08-23T17:26:12+00:00urn:sha1:f99509581ee73c1c2dbddb3398e87c098771d31f
Version numbers and dates (mostly wrong) from RCS keyword strings
removed from all source files; only the file name are kept.
