AArch64/ARM64: move ARM64 into AArch64's place This commit starts with a "git mv ARM64 AArch64" and continues out from there, renaming the C++ classes, intrinsics, and other target-local objects for consistency. "ARM64" test directories are also moved, and tests that began their life in ARM64 use an arm64 triple, those from AArch64 use an aarch64 triple. Both should be equivalent though. This finishes the AArch64 merge, and everyone should feel free to continue committing as normal now. llvm-svn: 209577

AArch64: TableGenerate system instruction operands. The way the named arguments for various system instructions are handled at the moment has a few problems: - Large-scale duplication between AArch64BaseInfo.h and AArch64BaseInfo.cpp - That weird Mapping class that I have no idea what I was on when I thought it was a good idea. - Searches are performed linearly through the entire list. - We print absolutely all registers in upper-case, even though some are canonically mixed case (SPSel for example). - The ARM ARM specifies sysregs in terms of 5 fields, but those are relegated to comments in our implementation, with a slightly opaque hex value indicating the canonical encoding LLVM will use. This adds a new TableGen backend to produce efficiently searchable tables, and switches AArch64 over to using that infrastructure. llvm-svn: 274576

[AArch64] Add an FP load balancing pass for Cortex-A57 For best-case performance on Cortex-A57, we should try to use a balanced mix of odd and even D-registers when performing a critical sequence of independent, non-quadword FP/ASIMD floating-point multiply or multiply-accumulate operations. This pass attempts to detect situations where the register allocation may adversely affect this load balancing and to change the registers used so as to better utilize the CPU. Ideally we'd just take each multiply or multiply-accumulate in turn and allocate it alternating even or odd registers. However, multiply-accumulates are most efficiently performed in the same functional unit as their accumulation operand. Therefore this pass tries to find maximal sequences ("Chains") of multiply-accumulates linked via their accumulation operand, and assign them all the same "color" (oddness/evenness). This optimization affects S-register and D-register floating point multiplies and FMADD/FMAs, as well as vector (floating point only) muls and FMADD/FMA. Q register instructions (and 128-bit vector instructions) are not affected. llvm-svn: 215199

[AArch64][v8.5A] Branch Target Identification code-generation pass The Branch Target Identification extension, introduced to AArch64 in Armv8.5-A, adds the BTI instruction, which is used to mark valid targets of indirect branches. When enabled, the processor will trap if an instruction in a protected page tries to perform an indirect branch to any instruction other than a BTI. The BTI instruction uses encodings which were NOPs in earlier versions of the architecture, so BTI-enabled code will still run on earlier hardware, just without the extra protection. There are 3 variants of the BTI instruction, which are valid targets for different kinds or branches: - BTI C can be targeted by call instructions, and is inteneded to be used at function entry points. These are the BLR instruction, as well as BR with x16 or x17. These BR instructions are allowed for use in PLT entries, and we can also use them to allow indirect tail-calls. - BTI J can be targeted by BR only, and is intended to be used by jump tables. - BTI JC acts ab both a BTI C and a BTI J instruction, and can be targeted by any BLR or BR instruction. Note that RET instructions are not restricted by branch target identification, the reason for this is that return addresses can be protected more effectively using return address signing. Direct branches and calls are also unaffected, as it is assumed that an attacker cannot modify executable pages (if they could, they wouldn't need to do a ROP/JOP attack). This patch adds a MachineFunctionPass which: - Adds a BTI C at the start of every function which could be indirectly called (either because it is address-taken, or externally visible so could be address-taken in another translation unit). - Adds a BTI J at the start of every basic block which could be indirectly branched to. This could be either done by a jump table, or by taking the address of the block (e.g. the using GCC label values extension). We only need to use BTI JC when a function is indirectly-callable, and takes the address of the entry block. I've not been able to trigger this from C or IR, but I've included a MIR test just in case. Using BTI C at function entries relies on the fact that no other code in BTI-protected pages uses indirect tail-calls, unless they use x16 or x17 to hold the address. I'll add that code-generation restriction as a separate patch. Differential revision: https://reviews.llvm.org/D52867 llvm-svn: 343967

[AArch64] Prefer Bcc to CBZ/CBNZ/TBZ/TBNZ when NZCV flags can be set for "free". This patch contains a pass that transforms CBZ/CBNZ/TBZ/TBNZ instructions into a conditional branch (Bcc), when the NZCV flags can be set for "free". This is preferred on targets that have more flexibility when scheduling Bcc instructions as compared to CBZ/CBNZ/TBZ/TBNZ (assuming all other variables are equal). This can reduce register pressure and is also the default behavior for GCC. A few examples: add w8, w0, w1 -> cmn w0, w1 ; CMN is an alias of ADDS. cbz w8, .LBB_2 -> b.eq .LBB0_2 ; single def/use of w8 removed. add w8, w0, w1 -> adds w8, w0, w1 ; w8 has multiple uses. cbz w8, .LBB1_2 -> b.eq .LBB1_2 sub w8, w0, w1 -> subs w8, w0, w1 ; w8 has multiple uses. tbz w8, #31, .LBB6_2 -> b.ge .LBB6_2 In looking at all current sub-target machine descriptions, this transformation appears to be either positive or neutral.

[AArch64][Falkor] Avoid HW prefetcher tag collisions (step 1) Summary: This patch is the first step in reducing HW prefetcher instruction tag collisions in inner loops for Falkor. It adds a pass that annotates IR loads with metadata to indicate that they are known to be strided loads, and adds a target lowering hook that translates this metadata to a target-specific MachineMemOperand flag. A follow on change will use this MachineMemOperand flag to re-write instructions to reduce tag collisions.

[AArch64] Add workaround for Cortex-A53 erratum (835769) Some early revisions of the Cortex-A53 have an erratum (835769) whereby it is possible for a 64-bit multiply-accumulate instruction in AArch64 state to generate an incorrect result. The details are quite complex and hard to determine statically, since branches in the code may exist in some circumstances, but all cases end with a memory (load, store, or prefetch) instruction followed immediately by the multiply-accumulate operation. The safest work-around for this issue is to make the compiler avoid emitting multiply-accumulate instructions immediately after memory instructions and the simplest way to do this is to insert a NOP. This patch implements such work-around in the backend, enabled via the option -aarch64-fix-cortex-a53-835769. The work-around code generation is not enabled by default. llvm-svn: 219603

It basically corrects two immediate values towards each other to make them equal. llvm-svn: 217220
