RE: Something fishy with the toolchain in unstable
Hi,
That is another error that could be resolved with following patch for gcc-5:
diff -upNr gcc-5.1.0-old/gcc/jit/jit-playback.c gcc-5.1.0/gcc/jit/jit-playback.c
--- gcc-5.1.0-old/gcc/jit/jit-playback.c 2015-02-03 17:19:58.000000000 +0000

I was testing this patch when this new issue occurred.
As I remember on Debian build MIPS is set to always use -fPIC.
Here is not configured with it and that is creating problem for pygccjit.
I think that fake.so was build without -fPIC and that was creating a problem.
I will check this again and send more info.
Regards,
Jurica

So in GCC 5, the FPXX ABI has been enabled by default.
FPXX does not work when compiling for mips1 CPUs so the GCC driver will
always pass '-march=mips2 -mfpxx' to as so that this error doesn't
occur. The error could also happen if the CPU was overridden in the .s
file (eg by '.set mips1').
Is it possible for you to get the contents of fake.s and the gcc driver
invocation which it tried to compile it with (it should be invoking
mipsel-linux-gnu-gcc-5 with some args)?
This build log was run against gcc-5_5.1.1-13 and gives a different
error:
https://buildd.debian.org/status/fetch.php?pkg=pygccjit&arch=mipsel&ver=0.4-4&stamp=1436320448
Thanks,
James
