| # For the pre-R6 code in arch/mips/vdso/vdso.h for locating |
| # the base address of VDSO, the linker will emit a R_MIPS_PC32 |
| # relocation in binutils > 2.25 but it will fail with older versions |
| # because that relocation is not supported for that symbol. As a result |
| # of which we are forced to disable the VDSO symbols when building |
| # with < 2.25 binutils on pre-R6 kernels. For more references on why we |
| # can't use other methods to get the base address of VDSO please refer to |
| # the comments on that file. |
| # |
| # GCC (at least up to version 9.2) appears to emit function calls that make use |
| # of the GOT when targeting microMIPS, which we can't use in the VDSO due to |
| # the lack of relocations. As such, we disable the VDSO for microMIPS builds. |
