The patch also adds parsing of 'mul vl' as needed for the VL-scaled immediate.

| | | | | | | | | | | | | | | | | | | | | | | | vector types. Summary: Added 'RegisterKind' to the VectorListOp structure, so that this operand type can be reused for SVE vector lists in a later patch. It also refactors the 'tryParseVectorList' function so it can be used directly in the ParserMethod of an operand. The parsing can now parse multiple kinds of vectors and recover if there is no match.

* [TargetParser] Use enum classes for various ARM kind enums.Florian Hahn2017-07-271-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Using c++11 enum classes ensures that only valid enum values are used for ArchKind, ProfileKind, VersionKind and ISAKind. This removes the need for checks that the provided values map to a proper enum value, allows us to get rid of AK_LAST and prevents comparing values from different enums. It also removes a bunch of static_cast from unsigned to enum values and vice versa, at the cost of introducing static casts to access AArch64ARCHNames and ARMARCHNames by ArchKind. FPUKind and ArchExtKind are the only remaining old-style enum in TargetParser.h. I think it's beneficial to keep ArchExtKind as old-style enum, but FPUKind can be converted too, but this patch is quite big, so could do this in a follow-up patch. I could also split this patch up a bit, if people would prefer that.

* Sort the remaining #include lines in include/... and lib/....Chandler Carruth2017-06-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | I did this a long time ago with a janky python script, but now clang-format has built-in support for this. I fed clang-format every line with a #include and let it re-sort things according to the precise LLVM rules for include ordering baked into clang-format these days. I've reverted a number of files where the results of sorting includes isn't healthy. Either places where we have legacy code relying on particular include ordering (where possible, I'll fix these separately) or where we have particular formatting around #include lines that I didn't want to disturb in this patch. This patch is *entirely* mechanical. If you get merge conflicts or anything, just ignore the changes in this patch and run clang-format over your #include lines in the files. Sorry for any noise here, but it is important to keep these things stable. I was seeing an increasing number of patches with irrelevant re-ordering of #include lines because clang-format was used. This patch at least isolates that churn, makes it easy to skip when resolving conflicts, and gets us to a clean baseline (again). llvm-svn: 304787

* AArch64AsmParser: don't try to parse “[1]” for non-vector register operandsSjoerd Meijer2017-02-271-25/+0
| | | | | | | | | There are no instructions that have "[1]" as part of the assembly string; FMOVXDhighr is out of date. This removes dead code. Differential Revision: https://reviews.llvm.org/D30165 llvm-svn: 296327
* AArch64AsmParser: tablegen the isBranchTarget helper functionsSjoerd Meijer2017-02-201-26/+4
| | | | | | | | | Use tablegen to autogenerate isBranchtarget helper functions. This is a cleanup that removes almost identical functions that differ only in a few constants. Differential Revision: https://reviews.llvm.org/D30160 llvm-svn: 295649
* [AArch64] AArch64AsmParser clean up of isImmediate functions. NFCSjoerd Meijer2017-02-161-142/+6
| | | | | | | | | | | Regression test neon-diagnostics.s needed changing because it now produces a more specific diagnostic about the immediate ranges. One change in the expected error message is not obvious, but there multiple candidate and it happens to pick the immediate diagnostic.
