2018-05-14[AArch64] Add combine pattern to fuse AESE/AESMC instructionsKyrylo Tkachov5-0/+139
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. (aarch64_crypto_aesd_fused): Likewise. * gcc.target/aarch64/crypto-fuse-1.c: New test. * gcc.target/aarch64/crypto-fuse-2.c: Likewise. From-SVN: r260234

2018-05-11[arm] PR target/85733 Restore be8 linking behaviour for ARMv6-M and products ↵Richard Earnshaw2-1/+6
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...

2018-05-11[arm] PR target/85606 prefer armv6s-m for armv6-m partsRichard Earnshaw2-6/+20
When Arm introduced ARMv6-M there were two variants, ARMv6-M and ARMv6S-M. The two differed only in support for the SVC instruction. Later on SVC was then made a mandatory part of ARMv6-M and the ARMv6S-M name was dropped. GCC and GAS, however still recognize both names and at least some versions of GAS still distinguish between the two. To address this, this patch changes the architecture for the ARMv6-m cortex parts (m0, m0plus, m1 and the variants will small multiply units) to use the ARMv6S-M name in conjunction with the assembler. This avoids problems with them rejecting code that was previously accepted with older versions of GCC where we did not pass an explicit architecture string through to the compiler when using -mcpu on the command line.
