== Progress == * Libssp support for AArch64 TCWG 23 Discussed with Matt and decided to assume "glibc" will export canary guard variable in TCB, for aarch64. It will export it as global variable for 32 bit. Working on top of Christophe patch that make frame grows downward.
* Look at builtin return address behavior in the absence of frame pointer. For X86_64 usage if __builtin_return_address(n) n>0 and -fomit-frame-pointer results in undefined behavior. In Ubuntu 12.04 the native GCC 4.7.1 resulted in segmentation fault on x86_64 machine for such a test. Currently planning to close this as undefined behavior in aarch64 as well. Discussing with Marcus on this. * TCWG-20 gprof support patches. Re based with latest trunk and regression tested. http://gcc.gnu.org/ml/gcc-patches/2013-07/msg01352.html http://gcc.gnu.org/ml/gcc-patches/2013-07/msg01333.html Misc * Tuesday spent on Internal (AMD) work. == Plan == * Continue Libssp support for AArch64 TCWG-23 * Update review comments and upstream gprof patches ==issues== * LTO/PGO work stopped now since libssp support priority is more. _______________________________________________ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-toolchain
