Bug 773661 – sys-libs/compiler-rt-sanitizers-11.0.1: Incorrect REQUIRED_USE and/or USE masks

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Luke-Jr 2021-03-01 22:36:39 UTC]

- sys-libs/compiler-rt-sanitizers-11.0.1::gentoo USE="asan clang libfuzzer msan profile scudo tsan ubsan xray (-cfi) (-dfsan) (-gwp-asan) (-hwasan) (-lsan) (-safestack) (-shadowcallstack) -test"
   The following REQUIRED_USE flag constraints are unsatisfied:
    ubsan? ( cfi )

Not only is the unmasked ubsan depending on the masked cfi USE flag, but at least ubsan works fine with 11.0.0...

    sys-libs/compiler-rt-sanitizers: Relax the component constraints
    
    Relax the component constraints to apply only with USE=test.  Reverse
    the constraint between ubsan and cfi -- it is cfi that requires ubsan
    for its tests to work.  At the same time, stub out automagically enabled
    cfi tests when ubsan is enabled but cfi is not.  This should fix
    impossible constraints on architectures that support ubsan but not cfi.
