sys-devel/crossdev applies host-specific masked use-flags to cross-building toolchain. Scenario: We want cross-compiling toolchain with target powerpc-unknown-linux-gnu, which runs on x86. For the target of the cross-compiler, we also want use-flag altivec. Problem: altivec cannot be enabled for cross-powerpc-unknown-linux-gnu/gcc Result: Compiler-errors because of invalid values for gcc-arguments -march=G4, -mtune=G4 and -maltivec. This breaks distcc, which I definitely want for an iBook G4 Reproducible: Always Steps to Reproduce: 1.USE="altivec" crossdev --g 4.1.2 --b 2.18-r1 --l 2.6.1 -k 2.6.23-r3 -s4 -t powerpc-linux-unknown-gnu # executed on x86 2.compile a package, e.g net-misc/x11-ssh-askpass-1.2.4-r1 on powerpc with USE="altivec" and distcc on the powerpc -- Actual Results: The actual error looks like: --- distcc[4762] ERROR: compile /var/tmp/ccache/drawing.tmp.belle-gunness.4758.i on 192.168.0.4/10 failed cc1: error: unrecognized command line option "-maltivec" drawing.c:1: error: bad value (G4) for -mtune= switch --- 192.168.0.4 is x86, System, ermerge runs on is powerpc-unknown-linux-gnu (iBook G4, 2005) Actually not all packages fail, but the one noted above and some others do. If you need more examples, let me know. Expected Results: Independent of host-arch, the compiler should be able to create altivec-enabled binaries for the target-arch.
