Just as the title says: gcc.dg/fixed-point/convert.c is much too big to run on
embedded targets like AVR.
Note that embedded systems are a main audience of ISO/IEC TR 18037,
and that these systems might have limited resources.
The original convert.c inflates to thousands of functions and set -O0.
Some targets need to emulate *everything*, even integer multiplication,
and the executable is much too fat.
The patch breaks up convert.c in parts so that an AVR ATmega103 device
with 128KiB for executable code (.text + .data + .rodata) can run them.
Ok for trunk?
