![]() In processRelocAux(), we handle errors before copy relocation/canonical PLT. This makes error checking a bit complex because we have to check for conditions that will be allowed by copy relocation/canonical PLT. Instead, move copy relocation/canonical PLT before error checking. This simplifies the previous clumsy error checking code `config->shared || (config->pie && expr == R_ABS && type != target->symbolicRel)` to the simple `config->isPic`. Some diagnostics can be reported in different ways. The code motion changes diagnostics for some contrived test cases: * copy-rel-pie-error.s -> copy-rel-pie2.s: It was rejected before but accepted now. ld.bfd also accepts the case. * copy-errors.s: "cannot preempt symbol" changes to "symbol 'bar' has no type" * got32{,x}-i386.s: the suggestion changes from "-fPIC or -Wl,-z,notext" to "-fPIE" * x86-64-dyn-rel-error5.s: one diagnostic changes for -pie case Reviewed By: peter.smith Differential Revision: https://reviews.llvm.org/D66007 llvm-svn: 369262 |

Benchmarking
In order to make sure various developers can evaluate patches over the same tests, we create a collection of self contained programs.
