Lephenixnoir	708ba1b017	libnum: unit tests, perf tests for num16, double limits ... * Add a unit testing framework in libnum/test/. Assertions are checked against sparse sets of input values (a couple thousands for each type), distributed fractally. * Add performance tests for num16. * Fix an overly ambitious substitution of /256 by >>8 in num16::mul, which would give some incorrect results for negative results. * Also fix an incorrect sign extension in the num16->num32 conversion. * Express comparison-with-int operators in terms of the integer even though some versions are faster when expressed in terms of the fixed- point value. This is because the integer is frequently known at compile-time. * Add minDouble and maxDouble static members to each num type to programmatically supply the bounds of the type.	2022-07-24 00:05:41 +01:00

Lephenixnoir	e90abaaabc	libnum: add tests for how optimized compiled assembly code is ... This change adds tests for libnum (run with `make -C build-x tests`) that compile example programs with g++ and evaluate how optimized the assembly code is. This is done by checking user-provided specifications of what instructions should and shouldn't be used against the compiled assembler.	2022-07-19 23:18:01 +01:00
