[XRay] ARM 32-bit no-Thumb support in LLVM This is a port of XRay to ARM 32-bit, without Thumb support yet. The XRay instrumentation support is moving up to AsmPrinter. This is one of 3 commits to different repositories of XRay ARM port. The other 2 are: https://reviews.llvm.org/D23932 (Clang test) https://reviews.llvm.org/D23933 (compiler-rt) Differential Revision: https://reviews.llvm.org/D23931 llvm-svn: 281878

[xray] Add XRay support for Mach-O in CodeGen Currently, XRay only supports emitting the XRay table (xray_instr_map) on ELF binaries. Let's add Mach-O support. Differential Revision: https://reviews.llvm.org/D26983 llvm-svn: 287734

[XRay][Arm] Repair XRay table emission on Arm32 and add tests to identify such problem earlier Summary: Emission of XRay table was occasionally disabled for Arm32, but this bug was not then detected because earlier (also by mistake) testing of XRay was occasionally disabled on 32-bit Arm targets. This patch should fix that problem and detect such problems in the future. This patch is one of a series, see also - https://reviews.llvm.org/D28623 Reviewers: rengolin, dberris Reviewed By: dberris Subscribers: llvm-commits, aemerson, rengolin, dberris, iid_iunknown Differential Revision: https://reviews.llvm.org/D28624 llvm-svn: 292516
