[Hexagon][NFC] Rename VK_Hexagon_PCREL to VK_PCRELOn PowerPC we will soon need to use pcrel to indicate PC Relative addressing.Renamed the Hexagon specific variant kind to a non target specific VK so thatit can be used on both Hexagon and PowerPC.Differential Revision: https://reviews.llvm.org/D74788 List of files: /llvm-project-15.0.7/llvm/lib/Target/Hexagon/MCTargetDesc/HexagonELFObjectWriter.cpp

0eaee545 - [llvm] Migrate llvm::make_unique to std::make_unique

Thu, 15 Aug 2019 15:54:37 +0000

[llvm] Migrate llvm::make_unique to std::make_uniqueNow that we've moved to C++14, we no longer need the llvm::make_uniqueimplementation from STLExtras.h. This patch is a mechanical replacementof (hopefully) all the llvm::make_unique instances across the monorepo.llvm-svn: 369013 List of files: /llvm-project-15.0.7/llvm/lib/Target/Hexagon/MCTargetDesc/HexagonELFObjectWriter.cpp

7ebfbebf - Include what you use in HexagonELFObjectWriter.cpp

Mon, 03 Jun 2019 09:56:40 +0000

Include what you use in HexagonELFObjectWriter.cppHexagonELFObjectWriter.cpp was not using any APIs from Hexagon.h, andwas only including it for transitive dependencies. Doing so isproblematic from include-what-you-use perspective, but it is also alayering issue (it creates a dependency cycle between the primaryHexagon target library and the MCTargetDesc library).llvm-svn: 362376 List of files: /llvm-project-15.0.7/llvm/lib/Target/Hexagon/MCTargetDesc/HexagonELFObjectWriter.cpp

2946cd70 - Update the file headers across all of the LLVM projects in the monorepo

Sat, 19 Jan 2019 08:50:56 +0000

Update the file headers across all of the LLVM projects in the monorepoto reflect the new license.We understand that people may be surprised that we're moving the headerentirely to discuss the new license. We checked this carefully with theFoundation's lawyer and we believe this is the correct approach.Essentially, all code in the project is now made available by the LLVMproject under our new license, so you will see that the license headersinclude that license only. Some of our contributors have contributedcode under our old license, and accordingly, we have retained a copy ofour old license notice in the top-level files in each project andrepository.llvm-svn: 351636 List of files: /llvm-project-15.0.7/llvm/lib/Target/Hexagon/MCTargetDesc/HexagonELFObjectWriter.cpp

Mon, 09 Oct 2017 23:53:15 +0000

[MC] Plumb unique_ptr through createELFObjectWriter toELFObjectWriter's constructor.Fixes the same ownership issue for ELF that r315245 did for MachO:ELFObjectWriter takes ownership of its MCELFObjectTargetWriter, so we want topass this through to the constructor via a unique_ptr, rather than a raw ptr.llvm-svn: 315254 List of files: /llvm-project-15.0.7/llvm/lib/Target/Hexagon/MCTargetDesc/HexagonELFObjectWriter.cpp

ecef1d9c - [Hexagon] Adding relocation for code size, cold path optimization allowing a 23-bit 4-byte aligned relocation to be a valid instruction encoding.

Tue, 16 Feb 2016 20:38:17 +0000

[Hexagon] Adding relocation for code size, cold path optimization allowing a 23-bit 4-byte aligned relocation to be a valid instruction encoding.The usual way to get a 32-bit relocation is to use a constant extender which doubles the size of the instruction, 4 bytes to 8 bytes.Another way is to put a .word32 and mix code and data within a function. The disadvantage is it's not a valid instruction encoding and jumping over it causes prefetch stalls inside the hardware.This relocation packs a 23-bit value in to an "r0 = add(rX, #a)" instruction by overwriting the source register bits. Since r0 is the return value register, if this instruction is placed after a function call which return void, r0 will be filled with an undefined value, the prefetch won't be confused, and the callee can access the constant value by way of the link register.llvm-svn: 261006 List of files: /llvm-project-15.0.7/llvm/lib/Target/Hexagon/MCTargetDesc/HexagonELFObjectWriter.cpp
