Subject: [PATCH 1/2] [AArch64][llvm] Unify AArch64 tests into a single file
(2/4) (NFC)
This is a series of patches (2/4) to unify assembly/disassembly of
recent AArch64 tests into a single file. The aim is to improve
consistency, so that all instructions and system registers are
thoroughly tested, and future test cases will be in a unified format.
This patch:
* removes .txt tests which have only one feature required
* makes the .s tests have a roundabout run line to test both encoding and assembly
* creates diagnostic tests when needed
* fixes naming convention of tests

Subject: [PATCH 2/2] fixup! [AArch64][llvm] Unify AArch64 tests into a single
file (2/4) (NFC)
This is a series of patches (2/4) to unify assembly/disassembly of
recent AArch64 tests into a single file. The aim is to improve
consistency, so that all instructions and system registers are
thoroughly tested, and future test cases will be in a unified format.
This patch:
* removes .txt tests which have only one feature required
* makes the .s tests have a roundabout run line to test both encoding and assembly
* creates diagnostic tests when needed
* fixes naming convention of tests
