--- Comment #24 from Jacob Lifshay <programmerjake at gmail.com> ---
The first fcvttg tests pass! (just testing input/output for f64->i32 js
conversion but not FPSCR, I copied the tests from:
https://chromium.googlesource.com/v8/v8.git/+/d94dfc2b01f988566aa410ce871588cf23b1285d/test/mjsunit/toint32.js
) I still need to check FPSCR output and test all the other modes and all the
other instructions.
