| Subject: lib/Kconfig.debug: fix frv build failure |
| |
| From: Sudip Mukherjee <sudipm.mukherjee@gmail.com> |
| |
| |
| [ Upstream commit da0510c47519fe0999cffe316e1d370e29f952be ] |
| |
| The build of frv allmodconfig was failing with the errors like: |
| |
| /tmp/cc0JSPc3.s: Assembler messages: |
| /tmp/cc0JSPc3.s:1839: Error: symbol `.LSLT0' is already defined |
| /tmp/cc0JSPc3.s:1842: Error: symbol `.LASLTP0' is already defined |
| /tmp/cc0JSPc3.s:1969: Error: symbol `.LELTP0' is already defined |
| /tmp/cc0JSPc3.s:1970: Error: symbol `.LELT0' is already defined |
| |
| Commit 866ced950bcd ("kbuild: Support split debug info v4") introduced |
| splitting the debug info and keeping that in a separate file. Somehow, |
| the frv-linux gcc did not like that and I am guessing that instead of |
| splitting it started copying. The first report about this is at: |
| |
| https://lists.01.org/pipermail/kbuild-all/2015-July/010527.html. |
| |
| I will try and see if this can work with frv and if still fails I will |
| open a bug report with gcc. But meanwhile this is the easiest option to |
| solve build failure of frv. |
| |
| Fixes: 866ced950bcd ("kbuild: Support split debug info v4") |
