Subject: [PATCH] xtensa: don't use unwind-dw2-fde-dip with elf targets
Define LIB2ADDEH_XTENSA_UNWIND_DW2_FDE to unwind-dw2-fde.c in
xtensa/t-elf and to unwind-dw2-fde-dip.c in xtensa/t-linux and use
LIB2ADDEH_XTENSA_UNWIND_DW2_FDE in LIB2ADDEH definition.
This fixes build for elf target with windowed xtensa core that currently
breaks with the following error message:
unwind-dw2-fde-dip.c:36:40: fatal error: elf.h: No such file or directory
2016-10-18 Max Filippov <jcmvbkbc@gmail.com>
libgcc/
* config/xtensa/t-elf (LIB2ADDEH_XTENSA_UNWIND_DW2_FDE): New
definition.
* config/xtensa/t-linux (LIB2ADDEH_XTENSA_UNWIND_DW2_FDE): New
definition.
* config/xtensa/t-windowed (LIB2ADDEH): Use
LIB2ADDEH_XTENSA_UNWIND_DW2_FDE defined by either xtensa/t-elf
or xtensa/t-linux.
