[Qemu-devel] QEMU TCG can't Generate Hardware Floating Point Instructions?

[傅 ㄏㄏ]

Dear all,
  
I am studying some research about QEMU's TCG and also trace a part of code 
translating TCG IRs to QEMU's host instructions recently.
I found that TCG use integer instructions to simulate the guest's floating 
point instructions instead of exploiting the FPU instructions supported by the 
host.
Is the reason in order to fit the result which the same program runs on the 
simulated machine?

Any help appreciated.

Thank you very much,
Alvin
