Author	SHA1	Message	Date
Roberto Ierusalimschy	1e0c73d5b6	Changes in the validation of UTF-8 All UTF-8 encoding functionality (including the escape sequence '\u') accepts all values from the original UTF-8 specification (with sequences of up to six bytes). By default, the decoding functions in the UTF-8 library do not accept invalid Unicode code points, such as surrogates. A new parameter 'nonstrict' makes them accept all code points up to (2^31)-1, as in the original UTF-8 specification.	6 years ago
Roberto Ierusalimschy	5e76a4fd31	New macros for arithmetic/bitwise operations in 'luaV_execute' 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).	6 years ago
Roberto Ierusalimschy	5382a22e0e	Corrections in the implementation of '%' for floats. 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.	6 years ago
Roberto Ierusalimschy	f99509581e	Removed extra information from RCS keyword strings Version numbers and dates (mostly wrong) from RCS keyword strings removed from all source files; only the file name are kept.	6 years ago
