| 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. |

| |
| * config/xtensa/uclinux.h (XTENSA_ALWAYS_PIC): Change to 0. |
