OK. It have been changed to sign-extended in the "processing of Narrower Values" section of the new spec(version 1.0.0.rc) . I'll fix this and update other nan-boxing processing in current implementation. 在 2021/12/26 上午9:42, liweiwei 写道: Sorry. In the old spec(version 0.41), nanboxing is not

Sorry. In the old spec(version 0.41), nanboxing is not totally disabled, but "NaN-boxing is limited to |XLEN| bits, not |FLEN| bits". Taking misa.mxl into acount, if misa.mxl is RV32, and maximum is RV64, this should be sign-extended. Is there any other new update for nanboxing  to the spec?

About source level debugging

Hi staffs at qemu, I'm a newcomer to qemu project. I'm currently trying to understand this great masterpiece, and in order to achieve this task. Source code level debugging is mandatory and necessary for me. Which IDE on Linux would you recommend to import the latest QEMU project? Could you provide
