Target stack-probe support configurable finely This adds capability to configure the target's stack probe support in a more precise manner than just on/off. In particular now we allow choosing between always inline-asm, always call or either one of those depending on the LLVM version. Note that this removes the ability to turn off the generation of the stack-probe attribute. This is valid to replace it with inline-asm for all targets because `probe-stack="inline-asm"` will not generate any machine code on targets that do not currently support stack probes. This makes support for stack probes on targets that don't have any right now automatic with LLVM upgrades in the future. (This is valid to do based on the fact that clang unconditionally sets this attribute when `-fstack-clash-protection` is used, AFAICT) cc #77885 r? `@cuviper` |
