- Authentication-results: sourceware.org; auth=none
The branch limits are a bit too far, resulting in reloc errors in rare
cases. Ok?
* config/v850/v850.md (branch_normal): Adjust branch limits.
(branch_invert): Likewise.
(branch_z_normal): Likewise.
(branch_z_invert): Likewise.
(branch_nz_normal): Likewise.
(branch_nz_invert): Likewise.
(jump): Likewise.
