* Swift support: add __attribute__((swift_async_context)) to args.cherry-pick-somethingTim Northover2020-12-1812-1/+59

* IR+AArch64: add a "swiftasync" argument attribute.Tim Northover2020-12-1833-17/+488
| | | | | | | | | | | | | | | | | | | | | | | This extends any frame record created in the function to include that parameter, passed in X22. The new record looks like [X22, FP, LR] in memory, and FP is stored with 0b0001 stored in bits 63:60 (CodeGen assumes they are 0b0000 in normal operation). The effect of this is that tools walking the stack should expect to see one of three values there: * 0b0000 => a normal, non-extended record with just [FP, LR] * 0b0001 => the extended record [X22, FP, LR] * 0b1111 => kernel space, and a non-extended record. All other values are currently reserved. If compiling for arm64e this context pointer is address-discriminated with the discriminator 0xc31a and the DB (process-specific) key. There is also an "i8** @llvm.swift.async.context.addr()" intrinsic providing front-ends access to this slot (and forcing its creation initialized to nullptr if necessary).

| * [CMake] Avoid __FakeVCSRevision.h with no git repositoryJonas Hahnfeld2020-12-172-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Set the return variable to "" in find_first_existing_vc_file to say that there is a repository, but no file to depend on. This works transparently for all other callers that handle undefinedness and equality to an empty string the same way. Use the knowledge to avoid depending on __FakeVCSRevision.h if there is no git repository at all (for example when building a release) as there is no point in regenerating an empty VCSRevision.h.

| * Don't error for zero-length arange entriesJames Henderson2020-12-162-11/+67
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Although the DWARF specification states that .debug_aranges entries can't have length zero, these can occur in the wild. There's no particular reason to enforce this part of the spec, since functionally they have no impact. The patch removes the error and introduces a new warning for premature terminator entries which does not stop parsing. This is a relanding of cb3a598c87db, adding the missing obj2yaml part that was needed. Fixes https://bugs.llvm.org/show_bug.cgi?id=46805. See also https://reviews.llvm.org/D71932 which originally introduced the error. Reviewed by: ikudrin, dblaikie, Higuoxing Differential Revision: https://reviews.llvm.org/D85313

| * [AArch64][GlobalISel] Narrow 128-bit regs to 64-bit regs in emitTestBitJessica Paquette2020-12-154-77/+67
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we have a 128-bit register, emitTestBit would incorrectly narrow to 32 bits always. If the bit number was > 32, then we would need a TB(N)ZX. This would cause a crash, as we'd have the wrong register class. (PR48379) This generalizes `narrowExtReg` into `moveScalarRegClass`. This also allows us to remove `widenGPRBankRegIfNeeded` entirely, since `selectCopy` correctly handles SUBREG_TO_REG etc. This does create some codegen changes (since `selectCopy` uses the `all` regclass variants). However, I think that these will likely be optimized away, and we can always improve the `selectCopy` code. It looks like we should revisit `selectCopy` at this point, and possibly refactor it into at least one `emit` function.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | check in realPathFromHandle() `GetFinalPathNameByHandleW(,,N,)` returns: - `< N` on success (this value does not include the size of the terminating null character) - `>= N` if buffer is too small (this value includes the size of the terminating null character) So, when `N == Buffer.capacity() - 1`, we need to resize buffer if return value is > `Buffer.capacity() - 2`. Also, we can set `N` to `Buffer.capacity()`. Thus, without this patch `realPathFromHandle()` returns unfilled buffer when length of the final path of the file is equal to `Buffer.capacity()` or `Buffer.capacity() - 1`.

| * [Sema] Introduce BuiltinAttr, per-declaration builtin-nessRaul Tambre2020-12-1419-216/+193
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of relying on whether a certain identifier is a builtin, introduce BuiltinAttr to specify a declaration as having builtin semantics. This fixes incompatible redeclarations of builtins, as reverting the identifier as being builtin due to one incompatible redeclaration would have broken rest of the builtin calls. Mostly-compatible redeclarations of builtins also no longer have builtin semantics. They don't call the builtin nor inherit their attributes. A long-standing FIXME regarding builtins inside a namespace enclosed in extern "C" not being recognized is also addressed. Due to the more correct handling attributes for builtin functions are added in more places, resulting in more useful warnings. Tests are updated to reflect that. Intrinsics without an inline definition in intrin.h had `inline` and `static` removed as they had no effect and caused them to no longer be recognized as builtins otherwise. A pthread_create() related test is XFAIL-ed, as it relied on it being recognized as a builtin based on its name. The builtin declaration syntax is too restrictive and doesn't allow custom structs, function pointers, etc. It seems to be the only case and fixing this would require reworking the current builtin syntax, so this seems acceptable.
