- Subject: [PATCH] Fix use of compact eh frames on MIPS
- MIME-Version: 1.0
- Content-Type: text/plain; charset=UTF-8
- Content-Transfer-Encoding: 8bit
- Newer MIPS toolchains use a different (compact) eh_frame format.
- libffi don't like them, so we have to switch to the older format.
- This patch add -mno-compact-eh to CFLAGS when compiling for
- Mips and compiler support it.
