Problem is branches in following thunks:

        .cfi_startproc
_ZThn8_N8TexmakerD1Ev:
        .PROC
        .CALLINFO FRAME=128,CALLS,SAVE_RP,ENTRY_GR=7
        .ENTRY
        b _ZN8TexmakerD2Ev
        ldo -8(%r26),%r26
        .EXIT
        .PROCEND
        .cfi_endproc

        .cfi_startproc
_ZThn8_N8TexmakerD0Ev:
        .PROC
        .CALLINFO FRAME=64,CALLS,SAVE_RP,ENTRY_GR=4
        .ENTRY
        b _ZN8TexmakerD0Ev
        ldo -8(%r26),%r26
        .EXIT        .PROCEND
        .cfi_endproc

We need to force targets into register %r1 and use bv branch to ensure
we can reach target.
