[PATCH] PR debug/81570: dwarf2cfi.c: Update cfa.offset in create_pseudo_cfg

[H.J. Lu]

execute_dwarf2_frame is called for each funtion.  But create_cie_data
is called only once to initialize cie_cfi_row for all functions.  Since
INCOMING_FRAME_SP_OFFSET may be different for each function, we can't
use the same INCOMING_FRAME_SP_OFFSET in cie_cfi_row for all functions.
This patch sets cie_cfi_row->cfa.offset to INCOMING_FRAME_SP_OFFSET in
create_pseudo_cfg which is called for each function.

Tested on x86-64.  OK for trunk?

Thanks.
