Corresponding source code
A jump to a different section is not relaxed correctly.
In the following assembly code:
.sect .text
.globl _start
_start:
.relax L1
ldx #table
bset 0,x #4
L1:
nop
bra toto
.sect .text.toto
.globl toto
toto:
rts
.sect .page0
.globl table
table: .long 0
When assembled and linked with --relax, the 'bra toto'
is adjusted but the branch becomes invalid. This comes
from the fact that 'toto' is not in the same
section as the 'bra' which use it.
