probes to userland programs and libraries without also needing to link libelf. dtrace -G places the __SUNW_dof symbol at the beginning of the DOF (DTrace probe and provider metdata) section in the generated object file; drti.o now just uses this symbol to locate the section. A complication occurs when multiple dtrace-generated object files are linked together, since the __SUNW_dof symbol defined in each file is global. This is handled by using objcopy(1) to convert __SUNW_dof to a local symbol once drti.o has been linked with the generated object file. Upstream, this is done using a linker feature not present in GNU ld. Differential Revision: https://reviews.freebsd.org/D1757 Reviewed by: rpaulo MFC after: 1 month Relnotes: yes |
