--- Comment #6 from hjl at gcc dot gnu.org <hjl at gcc dot gnu.org> --- Author: hjl Date: Mon Apr 16 18:42:57 2018 New Revision: 259408 URL: https://gcc.gnu.org/viewcvs?rev=259408&root=gcc&view=rev Log: i386: Move struct ix86_frame to machine_function Make ix86_frame available to i386 code generation. This is needed to backport the patch set of -mindirect-branch= to mitigate variant #2 of the speculative execution vulnerabilities on x86 processors identified by CVE-2017-5715, aka Spectre.
