Does this target support "protected" visibility?
Any target which dynamic libraries will naturally support something like "default" (meaning that the symbol is visible outside this shared object) and "hidden" (meaning that it isn't) visibilities, but "protected" is really an ELF-specific concept with weird semantics designed around the convenience of dynamic linker implementations. Which is not to suggest that there's consistent target-independent semantics for "default" visibility either; the entire thing is pretty badly mangled.

An optional hook that targets can implement to perform semantic checking on attribute((section("foo"))) specifiers.
In this case, "foo" is passed in to be checked. If the section specifier is invalid, the backend should return a non-empty string that indicates the problem.
This hook is a simple quality of implementation feature to catch errors and give good diagnostics in cases when the assembler or code generator would otherwise reject the section specifier.

Control whether the alignment of bit-field types is respected when laying out structures. If true, then the alignment of the bit-field type will be used to (a) impact the alignment of the containing structure, and (b) ensure that the individual bit-field will not straddle an alignment boundary.

If the alignment of the zero length bitfield is greater than the member that follows it, `bar', `bar' will be aligned as the type of the zero-length bitfield.
