Patch committed Valgrind revision 15917. |
When running the valgrind tests, the jm-insns test is segfaulting when it attempts to patch instructions as it deals with the ppc64 (BE) function descriptor. This is actually due to the RELRO option being enabled by default for the ppc64 (BE) platform, per an upstream binutils change. Patch to follow. Reproducible: Always Steps to Reproduce: 1. Build and run valgrind regression test on ppc64 platform with new binutils installed 2. specifically run the test " none/tests/ppc64/jm-insns -f " 3. see it segfault. Actual Results: ... PPC float load insns with one register + one 16 bits immediate args with flags update: Program received signal SIGSEGV, Segmentation fault. ... Expected Results: ... All done. Tested 77 different instructions Patch to disable the relro option for the jm-insns test to follow momentarily.
