2018-05-17aarch64: Retpoline (Spectre-V2 mitigation) for aarch64.master-dbcf2c2b2eChristoph Muellner
The compiler option -mindirect-branch=<value> converts indirect branch-and-link-register and branch-register instructions according to <value>. The default is ``keep``, which keeps indirect branch-and-link-register and branch-register instructions unmodified. ``thunk`` converts indirect branch-and-link-register/branch-register instructions to a branch-and-link/branch to a function containing a retpoline (to stop speculative execution) followed by a branch-register to the target. ``thunk-inline`` is similar to ``thunk``, but inlines the retpoline before the branch-and-link-register/branch-register instruction. ``thunk-extern`` is also similar to ``thunk``, but does not insert the functions containing the retpoline. When using this option, these functions need to be provided in a separate object file. The retpoline functions exist for each register and are named ``__aarch64_indirect_thunk_xN`` (N being the register number). It is also possible to override the indirect-branch setting for individual fuctions using the function attribute ``indirect_branch``. The actual retpoline instruction sequence, which prevents speculative indirect branches looks like this:: str x30, [sp, #-16]! bl 101f 100: //speculation trap wfe b 100b 101: //do ROP adr x30, 102f ret 102: //non-spec code ldr x30, [sp], #16 This patch has been tested with the included testcases and various other source bases (benchmarks, retpoline-patched arm64 kernel, etc.).

2018-05-14[AArch64] Add combine pattern to fuse AESE/AESMC instructionsktkachov
When the AESE,AESD and AESMC, AESMC instructions are generated through the appropriate arm_neon.h intrinsics we really want to keep them together when the AESE feeds into an AESMC and fusion is supported by the target CPU. We have macro-fusion hooks and scheduling model forwarding paths defined to facilitate that. It is, however, not always enough. This patch adds another mechanism for doing that. When we can detect during combine that the required dependency is exists (AESE -> AESMC, AESD -> AESIMC) just keep them together with a combine pattern throughout the rest of compilation. We won't ever want to split them. The testcases generate 4 AESE(D) instructions in a block followed by 4 AES(I)MC instructions that consume the corresponding results and it also adds a bunch of computations in-between so that the AESE and AESMC instructions are not trivially back-to-back, thus exercising the compiler's ability to bring them together. With this patch all 4 pairs are fused whereas before a couple of fusions would be missed due to intervening arithmetic and memory instructions. * config/aarch64/aarch64-simd.md (*aarch64_crypto_aese_fused): New pattern.

2018-05-11[arm] PR target/85733 Restore be8 linking behaviour for ARMv6-M and products ↵rearnsha
deriving from its capabilities My patch last year to automate passing the be8 flag to the linker had a nasty flaw in that I forgot entirely that the ARMv6-M architecture did not derive its capabilities directly from the ARMv6 capability list, but was a new group of capabilities (since it needs to leave out the ARM -- notm -- feature bit). The feature list defined was thus missing the be8 bit. Furthermore, any product derived from that feature group consequently lacked the be8 feature as well and this included all ARMv7 and ARMv8 parts. The fix is embarrassingly simple...
