--- Comment #15 from Ramana Radhakrishnan <ramana at gcc dot gnu.org> --- Author: ramana Date: Mon Feb 26 09:25:21 2018 New Revision: 257984 URL: https://gcc.gnu.org/viewcvs?rev=257984&root=gcc&view=rev Log: [Patch AArch64] Turn on frame pointer / partial fix for PR84521 This fixes a GCC-8 regression that we accidentally switched off frame pointers in the AArch64 backend when changing the defaults in the common parts of the code. This breaks an ABI decision that was made in GCC at the dawn of the port with respect to having a frame pointer at all times. If we really want to turn this off lets have a discussion around that separately. For now turn this back on and I believe this will leave PR84521 latent again with -fomit-frame-pointer and (hopefully) make the ruby issue go away. I'm asking Sudi to pick that up. Bootstrapped and regression tested on AArch64-none-linux-gnu but I see one regression in gcc.c-torture/execute/960419-2.c which needs to be looked at next (PR84528, thanks Kyrill).
