Hi,
I thought it may be a good idea to set the optimization level for the psim BSP
to `-O1`. The xilinx_zynq_a9_qemu has this and it is useful.
The change causes the number of test failures to jump from around 20 to over
230.
Is this expected?
Yes, this is a compiler bug/feature. GCC generates a floating point
instruction in a function which is called in ISR context. This leads to
an exception.
On SPARC using -O0 to run the tests is also problematic due to the much
higher stack usage.
