Subject: [PATCH] gcc: xtensa: don't force PIC for uclinux target
|
|
|
|
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.
