Created attachment 302019 [details, diff] *incomplete* patch for TEXTREL fix on ppc32 and ppc64 according to valgrind-3.7.0-non-exec-stack.patch, * coregrind/m_dispatch/dispatch-{ppc32,ppc64}-linux.S * coregrind/m_syswrap/syscall-{ppc32,ppc64}-linux.S should not omit ".section .note.GNU-stack,"",@progbits". and according to build.log, * coregrind/m_cpuid.S * coregrind/m_trampoline.S are also used for {ppc32,ppc64}. former does omit ".section .note.GNU-stack,"",@progbits", latter does not. even if using w/ this patch, TEXTREL QA still appears. maybe, real fix needs to investigate {ppc32,ppc64}'s inline asm?
*sigh*, replacing -Os to -O2 solves this bug w/o attached patch... maybe my toolchain breaks some programs if w/ -Os.
(In reply to comment #2) > *sigh*, replacing -Os to -O2 solves this bug w/o attached patch... > maybe my toolchain breaks some programs if w/ -Os. While I would ideally we would support all CFLAGS, that's not going to happen with valgrind. Various compiler optimizations definitely break valgrinds delicate logic.
