If in doubt, use ELDK. All examples were compiled with ELDK 4.2 (GCC 4.2.2) for ppc_8xx. > ## 4.4.5 has been patched to support msingle-pic-base > CROSS_COMPILE=powerpc-4.4.5_softfloat-linux-gnu- ./MAKEALL TQM855L TQM860L > Configuring for TQM855L board... > text data bss dec hex filename > 267022 5284 27200 299506 491f2 ./u-boot > Configuring for TQM860L board... > text data bss dec hex filename > 267043 5284 27200 299527 49207 ./u-boot I don't have gcc 4.4.x here for testing. > So I strongly suspect that as soon as you move your gcc version upwards, it > will break > these boards too. Yes, but for other reasons. Recent versions of GCC (gcc 4.5.x) cannot be used to build this code at all until they get fixed, as -Os is not working, and the code size explodes completely. See GCC bugs 43810, 48278, and 45053. > > I will not apply either of these commits - neither the reverted one, > > nor this additional one, as both of them grow the memory footprint > > instead of redusing it as you promised in the commit message. > > You should read the commit msg again. It requires a gcc which > supports -msingle-pic-base. As the majority of gcc versions outthere does not support this feature, we are trading a (slight?) advantage for a very limited group against disadvantages for a very large group (probably everyone else but you). > I still don't know why it broke with your gcc but I suspect > it is due to -fno-jump-tables(which is in the msingle-pic-base patch). > Seems like that option in your case makes the code bigger. Indeed. As I cannot see any advantages, I reject this stuff, at least for now.
