Hi,
Kaz Kojima provides regular testresults for GCC on sh4-linux :
4.7:
http://gcc.gnu.org/ml/gcc-testresults/2011-03/msg02619.html
4.6:
http://gcc.gnu.org/ml/gcc-testresults/2011-03/msg01500.html
He also seems active fixing bugs on this platform, eg:
http://gcc.gnu.org/ml/gcc-patches/2011-03/msg01213.html
He commited about two patch a month on average according to
gcc/ChangeLog for 2009-2011.
Renesas donated an SH4 board to the GCC Compile Farm project (1). This
donation has not been made public yet since I'm waiting for wheezy and
full 512MB RAM support (current lenny based release I tested supports
only 128MB due to kernel issues), but it should be soon and so the
sh4-linux platform will be available for all upstream free software
developpers in case the need arises. I will try native GCC bootstrap on
it.
Note: I'm no SH4 expert and I don't know personally Kaz Kojima,
just looking at my inbox archives :).
Sincerely,
Laurent
