[cfe-dev] [llvm-dev] 10.0.1-rc4 tagged

[Kevin Neal via cfe-dev]

If there is an rc5 is it too late to get these changes in? I'd like an authoritative yes or no for the below-mentioned bug report. I'd guess it is too late but it's not my decision. And the code did just go in the tree today.

    Reland "[FPEnv][Clang][Driver] Disable constrained floating point on targets lacking support."

    We currently have strict floating point/constrained floating point enabled
    for all targets. Constrained SDAG nodes get converted to the regular ones
    before reaching the target layer. In theory this should be fine.

    However, the changes are exposed to users through multiple clang options
    already in use in the field, and the changes are _completely_ _untested_
    on almost all of our targets. Bugs have already been found, like
    "https://bugs.llvm.org/show_bug.cgi?id=45274".

    This patch disables constrained floating point options in clang everywhere
    except X86 and SystemZ. A warning will be printed when this happens.

    Use the new -fexperimental-strict-floating-point flag to force allowing
    strict floating point on hosts that aren't already marked as supporting
    it (X86 and SystemZ).
