Roman Lebedev ba545c814b [Sema] Try 2: Attempt to perform call-size-specific `__attribute__((alloc_align(param_idx)))` validation Summary: `alloc_align` attribute takes parameter number, not the alignment itself, so given just the attribute/function declaration we can't do any sanity checking for said alignment. However, at call site, given the actual `Expr` that is passed into that parameter, we //might// be able to evaluate said `Expr` as Integer Constant Expression, and perform the sanity checks. But since there is no requirement for that argument to be an immediate, we may fail, and that's okay. However if we did evaluate, we should enforce the same constraints as with `__builtin_assume_aligned()`/`__attribute__((assume_aligned(imm)))`: said alignment is a power of two, and is not greater than our magic threshold This was initially committed in `c2a9061ac5` but reverted in `00756b1823` because of suspicious bot failures.

//===----------------------------------------------------------------------===//
// C Language Family Front-end
//===----------------------------------------------------------------------===//

Welcome to Clang.  This is a compiler front-end for the C family of languages
(C, C++, Objective-C, and Objective-C++) which is built as part of the LLVM
compiler infrastructure project.

Unlike many other compiler frontends, Clang is useful for a number of things
beyond just compiling code: we intend for Clang to be host to a number of
different source-level tools.  One example of this is the Clang Static Analyzer.

If you're interested in more (including how to build Clang) it is best to read
the relevant web sites.  Here are some pointers:

Information on Clang:             http://clang.llvm.org/

If you have questions or comments about Clang, a great place to discuss them is
on the Clang development mailing list:

If you find a bug in Clang, please file it in the LLVM bug tracker:
