Hi, This patch backports r11-4980 to GCC-10, as it fixes an ICE that could occur on some targets.
Regression tested on x86_64-linux-gnu and committed to branch. Regards Iain --- gcc/d/ChangeLog: * intrinsics.cc (expand_intrinsic_copysign): Explicitly determine which built-in copysign function to call.
