The libphobos.phobos/std_math_hardware.d test FAILs on SPARC: FAIL: libphobos.phobos/std_math_hardware.d (test for excess errors) UNRESOLVED: libphobos.phobos/std_math_hardware.d compilation failed to produce executable Excess errors: libphobos.phobos/std_math_hardware.d:7: error: undefined identifier 'FloatingPointControl' There's currently no support for IeeeFlags on SPARC. One part of an implementation has already been committed to upstream phobos commit aa963e98c55b36b5d608f9443d96c66b63d16d8f Author: Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE> Date: Thu Feb 19 12:47:58 2026 +0100 std/math/hardware.d: Partial IeeeFlags implementation on SPARC (#10958) but the actual implementation is specific to a GDC-specific part of hardware.d which isn't upstream yet. This patch provides that part. Tested on sparc-sun-solaris2.11 and sparc64-unknown-linux-gnu. 2025-12-19 Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE> libphobos: PR d/123202 * src/std/math/hardware.d (getIeeeFlags) [GNU && SPARC_Any]: Implement.
