The reason:
All RunFloat64Sin/RunFloat64Cos/RunFloat64Expm1/RunFloat64Tan/Ieee754.Expm1/Ieee754.Cos/Ieee754.Tan test cases
use the C++ function to generate the expected value or result. So for x87, all those expected value or result are
extended double precision as the extended double precision is default for x87 Gcc compiler and std lib on linux platform.
The issue is:
For RunFloat64Sin/RunFloat64Cos/RunFloat64Expm1/RunFloat64Tan test cases, the expected values generated by C++ function
are extended double precision, the results generated by X87 jitted code are double precision according to the ECMA standard.
The comparison of different precisons caused some of those test cases failed.
For Ieee754.Expm1/Ieee754.Cos/Ieee754.Tan test cases, the expected values are pre-defined double precision values, the results
generated by C++ function are extended double precision. The comparison of different precisons caused some of those test cases
failed too.
This CL disables RunFloat64Sin/RunFloat64Cos/RunFloat64Expm1/RunFloat64Tan/Ieee754.Expm1/Ieee754.Cos/Ieee754.Tan test cases for x87.
