CVSROOT:/cvs Module name:src Changes by: morti...@cvs.openbsd.org2019/07/31 19:09:09 Modified files: gnu/llvm/lib/Target/AArch64: AArch64TargetMachine.cpp Log message: The GlobalISel IRTranslator pass assumes that it is safe to use the LOAD_STACK_GUARD pseudo without consulting the value of useLoadStackGuardNode(), and then tries to add the return from getSDagStackGuard() as a parameter without consulting the return from getIRStackGuard() to see if it should do that. This means that the GlobalISel IRTranslator's implementation for Intrinsic::stackprotector is broken for platforms that implement getIRStackGuard() like we do, and this causes a segfault later when the incomplete LOAD_STACK_GUARD pseudo is lowered in the back end. Since GlobalISel is disabled on aarch64 most of the time anyway, add a bit that disables it for OpenBSD/aarch64 all the time. Fixes a crash when building on aarch64 without retguard, with a stack protector and without optimizations, which manifests when building cross-tools. ok patrick@ deraadt@

This change adds a constraint that the name passed to the RETGUARD_* macros must correspond to the name in the corresponding ENTRY which starts the function (or a function which appears beforehand in the same file). Since we use the distance from the ENTRY definition to calculate how much padding to insert, the ENTRY symbol must be in scope at assembly time. This is almost always the case already, since it is the natural way to name the retguard symbols so they remain unique. ok deraadt@
