| 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. |
