How can I set the two-bit rounding control (RC) field of the FPU control word to 10 (round towards +infinity) using GAS in C.

Must use format

asm(

);

should only be about 7 lines of code altogether.

first push RC register onto the stack, flip the bits so that bit 10 & 11 are turned "on"

I'm unsure how to write this in the floating point stack using the correct syntax.

Better to post your code here, as text. – chux - Reinstate Monica Mar 11 '22 at 22:28
