- Subject: [PATCH 1/9] Revert "sparc: use HIDDEN_JUMPTARGET for errno"
- This reverts commit f51fb26dbcceee9e48d10facc830bd4a549f6cc2.
- This fixes linking error for sparc build.
- While building a sparc system you get following linking error:
- libc/sysdeps/linux/sparc/pipe.S:54: undefined reference to `__GI___errno_location'
- Removing the HIDDEN_JUMPTARGET fixes the issue, while using gcc 4.8.3/binutils 2.24.
- The definition of __errno_location was changed recently here:
