[PATCH v2] gcc: xtensa: don't force PIC for uclinux target

2018-11-05 Thread Max Filippov
xtensa-uclinux uses bFLT executable file format that cannot relocate fields representing offsets from data to code. C++ objects built as PIC use offsets to encode FDE structures. As a result C++ exception handling doesn't work correctly on xtensa-uclinux. Don't use PIC by default on xtensa-uclinux.
