The attached patch fully implements IEEE exceptions on the SPARC target.
Nice work, thank you. Do you know of any code that uses the exceptions?
The flags enabling exceptions could be recorded to TB flags so that the
check code is generated only when needed, see cpu-exec.c:180.

I guess no code is using IEEE exceptions to generate a trap, because

Hi,
The attached patch fully implements IEEE exceptions on the SPARC target.
Some more details:
- Any floating point operation that does not trap should clear the ftt
flags. Similary, any floating point operation that does not generate
an IEEE exception should clear the cexec flags. In the
