Using the Debian cross image I get: /home/phil/source/qemu/tests/docker/docker.py --engine auto cc --cc mips64el-linux-gnuabi64-gcc -i qemu/debian-mips64el-cross -s /home/phil/source/qemu -- -Wall -Werror -O0 -g -fno-strict-aliasing -mabi=n32 -march=r5900 /home/phil/source/qemu/tests/tcg/mips/test-r5900-dmult.c -o test-r5900-dmult -static cc1: error: unsupported combination: -march=r5900 -mhard-float -mdouble-float No clue what is setting '-mhard-float -mdouble-float' yet. >> >> Is it necessary to rebuild the toolchain every time? > > No. > >> Also, perhaps a >> generic MIPS suite can be used; it shouldn't to necessary to have one >> specifically made for the R5900 (except libc, if needed, I guess). > > We want it to build TCG tests.
