Importance: High This patch is completely missing documentation (in *.texi files) of the new options, attribute, built-in functions etc. You appear to be adding quite target-specific things to the architecture-independent compiler. If the attribute, for example, is to be architecture-independent, the documentation needs to define semantics for it that make sense on any architecture (or any architecture providing such features), not just on x86; the patch submission needs to justify the design choices of what is target-specific and what is target-independent. (Cf. MPX where there are various architecture-independent features for which a software implementation would be logically possible, although actually the only implementation of those features in GCC is for MPX hardware.) I don't think this patch would even build for non-x86 targets, because you're putting completely x86-specific references such as TARGET_CET and gen_nop_endbr in target-independent files. -- Joseph S.
