File ipxe-use-gcc6-for-more-compact-code.patch of Package qemu.8413
ipxe: use gcc6 for more compact code We have a strict size limit of 64K which needs to be enforced for pxe-virtio.rom for migration compatibility. The v4.8 gcc compiler used in SLE12 doesn't produce as compact code as does more recent gcc compilers, and the pxe-virtio.rom produced with it doesn't fit in 64K anymore without taking extraordinary efforts. I was unable to find enough opportunities in the ipxe code and data to reduce its size, and found that using a more recent compiler would be the best solution to keeping the rom size within the 64K size limit.
