This is LLVM part of D56663
Linker scripts shipped by TI require to have every
interrupt vector in a separate section with a specific name:
SECTIONS
{
__interrupt_vector_XX : { KEEP (*(__interrupt_vector_XX )) } > VECTXX
...
}
Follow the requirement emit the section for every vector
which contain address of interrupt handler:
.section __interrupt_vector_XX,"ax",@progbits
.word %isr%
