The genvdso program modifies the debug and stripped versions of the VDSOs in place, and errors if the modification has already taken place. Unfortunately this means that a rebuild which tries to rerun genvdso to generate vdso*-image.c without also rebuilding vdso.so.dbg (for example if genvdso.c is modified) hits a build error like this: arch/mips/vdso/genvdso 'arch/mips/vdso/vdso.so.dbg' already contains a '.MIPS.abiflags' section This is fixed by reorganising the rules such that unmodified .so files have a .raw suffix, and these are copied in the same rule that runs genvdso on the copies. I.e. previously we had: cmd_vdsold: link objects -> vdso.so.dbg cmd_genvdso: strip vdso.so.dbg -> vdso.so run genvdso -> vdso-image.c and modify vdso.so.dbg and vdso.so in place Now we have: cmd_vdsold: link objects -> vdso.so.dbg.raw a new cmd_objcopy based strip rule (inspired by ARM): strip vdso.so.dbg.raw -> vdso.so.raw cmd_genvdso: copy vdso.so.dbg.raw -> vdso.so.dbg copy vdso.so.raw -> vdso.so run genvdso -> vdso-image.c and modify vdso.so.dbg and vdso.so in place Signed-off-by: James Hogan <james.hogan@imgtec.com> Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/13250/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org> |
