Hello,
I try to add a nios2 multilib to support the "Nios II Floating Point
Hardware 2 Component":
https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/ug/ug_nios2_custom_instruction.pdf
If I add all custom instructions supported by the component, then I get
an error in libatomic since -Werror is used:
cc1: error: switch '-mcustom-fmins' has no effect unless
'-ffinite-math-only' is specified [-Werror]
cc1: error: switch '-mcustom-fmaxs' has no effect unless
'-ffinite-math-only' is specified [-Werror]
cc1: error: switch '-mcustom-round' has no effect unless
'-fno-math-errno' is specified [-Werror]
I am not sure how to fix this.
