Bug ID: 63223
Summary: [avr] Make jumptables work with
-Wl,--section-start,.text=
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: gjl at gcc dot gnu.org
avr-gcc assumes that jumptables in section .progmem.gcc_sw_table are located in
the lower 64k of flash and uses LPM to read from these tables.
This does no more hold if the code is shifted to a higher address by, e.g.
-Wl,--section-start,.text=... which is commonly used with bootloadres.
This PR implements ELPM to access jumptables as needed.
