FYI, I updated the avrtest core simulator hosted in the WinAVR project
at sourceforge. The avrtest simulator can now be used to reg-test
avr-gcc testsuite against xmega core.
As target I used atxmega128a3 and the test results are exactly the same
as for atmega128, except for some functions that use builtin return or
instrument-functions that trigger builtin return.
This is because flash size of atxmega128a3 is > 64Ki words, thus a
warning from avr.c
warning: 'builtin_return_address' contains only 2 bytes of address
I did not try to use PSImode as potential fix; but even with PSImode
there would be a warning from the assembler like
.warning "assembling 24-bit address needs binutils extension for
" hh8(<symbol>)"
The simulator does not test I/O and the new operand modifier %i, of
course, but I heard that guys using 4.7 snapshots could compile and run
xmega programs without problems.
