If there is a difference between them. I think we should fix

Since I think "zvfh_zfh" should not be different with "zfh_zvfh"
It's possible. Let me debug it and see if there's a problem.
I don't think it is different. Just checked and it still works for me.
Could you please tell me how you invoke the testsuite?
This looks to be the difference between the linux and elf versions of
gcc. The elf version of gcc we are build will have this problem, the
linux version of gcc will not. I think the linux version of gcc has a
wrong behavior.:

It looks like this commit[1] from you make the difference between elf
and linux. Can you help to see if it makes sense to behave differently
now? elf version --with-arch is rv32gcv_zvfh_zfh, and the user will get
an error with -march=rv32gcv_zfh. linux version will not.
