Hi all,
This is a simple patch that moves the alignment recording code in
mapping_state early before it returns. So that, all code related
alignment will be recorded.
For example, one case missed is for .inst directive. When .inst is
processed, it will call frag_align_code first, which calls
mapping_state_2 and set current state to MAP_INSN. Later when
mapping_state is called, it will return early, because there is no state
change.
For example,
.text
.short 0xffff
.inst 0x12345678 --> this will set MAP_INSN
ret --> while processing this insn, mapping_state will
early return as there is no state change.
The alignment of .text section will not be recorded.
Okay to commit?
Regards,
Renlin Li
