The <code>PCALIGN</code> pseudo-instruction is used to indicate that the next instruction should be aligned
to a specified boundary by padding with no-op instructions.

It is currently supported on arm64, amd64, ppc64, loong64 and riscv64.

from the value obtained by executing and rounding the instructions individually.
An explicit floating-point type <a href="#Conversions">conversion</a> rounds to
the precision of the target type, preventing fusion that would discard that rounding.
