* Bumping SEMVER to v3.74.1 * removing extraneous function * adding QSNR to the benchmarking * adding range reporting for the Scalar type * adding elastic integer traits to try to disambiguate type_tag (not entirely successful yet) * compilation fix for gcc and clang * streamlining elastic binary integer API test * renaming Adaptive to Elastic * expanding QSNR experiment to sample across multiple sets * generalizing qsnr as a service * adding is_subnormal() attribute method * specialized posit<16,2> engineering * redefining nibble markers to be 0-based * WIP: fast posit<16,2> addition * restructuring specialized posits test infrastructure * adding a posit oracle as a separate data type to be used to validate specialized posits * adding a arithmetic debug test * Implement specialized posit<16,2> addition (#403) * rearchitecting the regression test suite to have a universal number system check * cleaning up include file dependencies * bug fix in the argument order of ReportBinaryArithmeticError as called in the posit test suite * WIP: bug fixes for add/sub, not quite there yet * compilation fix for gcc and clang * WIP: fast posit<16,2> subtraction checks * Implement specialized posit<16,2> sub, mul, div (#404) Div is not working 100% yet * enabling the regression level 1 again in specialized posit<16,2> while we are RCAing the div on extreme regime values * bug fix and reporting improvement of posit randoms * WIP: cleaning up posit<16,1> and posit<16,2> * adding a math library to the posito oracle so we can use it to compare native implementations * WIP: building test infrastructure to RCA specialized posit implementations * WIP: RCAing specialized posit<16,2> divide operator * adding multiplication tests for specialized posits * WIP: code hygiene for old posit code * WIP: redoing the fast posit<16,2> arithmetic operators * restoring the multiplication operator algorithm * configuring a regression test for fast posit multiplication * configuring a regression test for fast posit addition * test name edit * configuring a regression test for fast posit division: not enabled yet * adding a regression suite for fast posit subtraction * code hygiene for old posit code * bug fix in fast posit<32,2> that code hygiene activities had introduced * WIP: fixed bugs in regime and exponent fields for fast posit<16,2>, rounding still buggy * bug fix of bitnplusone calculation in divround of posit<16,2> * code hygiene posit<32,2> * bug fix div operator for fast posit<16,2> * adding new posit attribute functions: maxprecision_max/min, this is the largest value of Regime 0, and the smallest value of Regime -1 * adding full regression results for reference --------- Co-authored-by: David Mallasén Quintana <[email protected]>
