Commit 1af6209d64dc503800797b647f9c281cc2c4ec87 by grimar [llvm-readelf] - Improve dumping of objects without a section header string table. We have a test/Object/no-section-header-string-table.test which checks what happens when an object does not have a section header string table. It does not check the full output though. Currently our output is different from GNU readelf, because the latter prints "<no-strings>" instead of a section name, while we print nothing. This patch fixes this, adds a proper test case and removes the one from test/Object, as it is not a right folder for llvm-readelf tests. Differential revision: https://reviews.llvm.org/D73193

Commit ba545c814bc19c3b1ec9ce88a7f13575e0e4ce1d by lebedev.ri [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 c2a9061ac5166e48fe85ea2b6dbce9457c964958 but reverted in 00756b182398b92abe16559287467079087aa631 because of suspicious bot failures.

Commit 2ee218f3653fcfd135fc5087a698424f90a9a499 by courbet [llvm-exegesis][NFC] Simplify code. Summary: What we're redoing already exists in the X86 backend, it's called `X86II::getOperandBias`.

Commit 805c157e8aeee24adec897bed42662733eb0d710 by gchatelet [Alignment][NFC] Deprecate Align::None() Summary: This is a follow up on https://reviews.llvm.org/D71473#inline-647262. There's a caveat here that `Align(1)` relies on the compiler understanding of `Log2_64` implementation to produce good code. One could use `Align()` as a replacement but I believe it is less clear that the alignment is one in that case.
