I would recommend using GCC 8.2.0, by omitting the --binutils and --gcc
options to crossdev, unless you would like to debug this particular
combination of GCC and Glibc (which I can confirm seems broke). Updated
and much simplified R5900 patches are available in my previous email:
http://lists.nongnu.org/archive/html/qemu-devel/2018-11/msg03649.html
Hopefully soon, with upcoming GCC and Gblic releases, no R5900 patches
are needed at all. Also, a new -mfix-r5900 option has been proposed to
both GAS and GCC:
http://www.sourceware.org/ml/binutils/2018-10/msg00301.html
https://gcc.gnu.org/ml/gcc-patches/2018-11/msg00773.html
With that option one can compile e.g. MIPS II or MIPS III that also
work with the R5900.
The R3900 and the R5900 could for example run the same programs then,
and I do hope that Philippe will be able to merge his R3900 series
eventually.
