ARMTargetParser: Make BSD Thumb/BE armv6 work
Simple change to make arch like "thumbv6" and "armbev6" to return the correct CPU for FreeBSD and NetBSD. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@238353 91177308-0d34-0410-b5e6-96231b3b80d8 |

Move parseSubArch to ARMTargetParser. NFC
Using getCanonicalArchName() is the right way to parse ARM arch names. Mapping ARMTargetParser IDs to Triple Arch IDs is temporary, until they are merged into a TargetDescription class. This was the last LLVM FIXME to move things to ARMTargetParser. Now on to Clang and beyond. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@238110 91177308-0d34-0410-b5e6-96231b3b80d8 |

Adding profile and version parsers to ARMTargetParser
This allows us to match armv6m to default to thumb, but will also be used by Clang's driver and remove the current incomplete copy in it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@238036 91177308-0d34-0410-b5e6-96231b3b80d8 |

Make Triple::parseARMArch use ARMTargetParser
Simplifying Triple::parseARMArch, leaving all the parsing to ARMTargetParser.
This commit also adds AArch64 detection to ARMTargetParser canonicalization,
and a two RedHat arch names (v{6,7}hl, meaning hard-float / little-endian).
Adding enough unit tests to cover the basics. Clang checks fine.

Get Triple::getARMCPUForArch() to use TargetParser
First ARMTargetParser FIXME, conservatively changing the way we parse CPUs in the back-end. Still not perfect, with a lot of special cases, but moving towards a more generic solution. Moving all logic to the target parser made some unwritten assumptions about architectures in Clang to break. I've added a lot of architectures required by Clang, and default to CPUs that Clang believes it should (and I agree). I've also added a lot of unit tests, with the correct CPU for each architecture, and Clang seems to be working correctly, too. It also became clear that using "unsigned ID" as the argument for the get methods makes it hard to know what ID, so I also changed the argument names to match the enum type names. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@237797 91177308-0d34-0410-b5e6-96231b3b80d8 |

TargetParser: FPU/ARCH/EXT parsing refactory - NFC
This new class in a global context contain arch-specific knowledge in order
to provide LLVM libraries, tools and projects with the ability to understand
the architectures. For now, only FPU, ARCH and ARCH extensions on ARM are
supported.
Current behaviour it to parse from free-text to enum values and back, so that
all users can share the same parser and codes. This simplifies a lot both the
ASM/Obj streamers in the back-end (where this came from), and the front-end
parsers for command line arguments (where this is going to be used next).
The previous implementation, using .def/.h includes is deprecated due to its
inflexibility to be built without the backend support and for being too
cumbersome. As more architectures join this scheme, and as more features of
such architectures are added (such as hardware features, type sizes, etc) into
a full blown TargetDescription class, having a set of classes is the most
sane implementation.
The ultimate goal of this refactor both LLVM's and Clang's target description
classes into one unique interface, so that we can de-duplicate and standardise
the descriptions, as well as make it available for other front-ends, tools,
etc.
The FPU parsing for command line options in Clang has been converted to use
this new library and a number of aliases were added for compatibility:
* A bogus neon-vfpv3 alias (neon defaults to vfp3)
* armv5/v6
* {fp4/fp5}-{sp/dp}-d16
Next steps:
* Port Clang's ARCH/EXT parsing to use this library.
* Create a TableGen back-end to generate this information.
* Run this TableGen process regardless of which back-ends are built.
* Expose more information and rename it to TargetDescription.
* Continue re-factoring Clang to use as much of it as possible.

[ARM] Reject invalid -march values
Restructure Triple::getARMCPUForArch so that invalid values will return nullptr, while retaining the behaviour that an argument specifying no particular architecture version will give a default CPU. This will be used by clang to give an error on invalid -march values. Also restructure the extraction of the architecture version from the MArch string a little to hopefully make what it's doing clearer.

[SystemZ] Support transactional execution on zEC12
The zEC12 provides the transactional-execution facility. This is exposed to users via a set of builtin routines on other compilers. This patch adds LLVM support to enable those builtins. In partciular, the patch: - adds the transactional-execution and processor-assist facilities - adds MC support for all instructions provided by those facilities - adds LLVM intrinsics for those instructions and hooks them up for CodeGen - adds CodeGen support to optimize CC return value checking Since this is first use of target-specific intrinsics on the platform, the patch creates the include/llvm/IR/IntrinsicsSystemZ.td file and hooks it up in Intrinsics.td. I've also changed Triple::getArchTypePrefix to return "s390" instead of "systemz", since the naming convention for GCC intrinsics uses "s390" on the platform, and it neemed more straight- forward to use the same convention for LLVM IR intrinsics. An associated clang patch makes the intrinsics (and command line switches) available at the source-language level. For reference, the transactional-execution instructions are documented in the z/Architecture Principles of Operation for the zEC12: http://publibfp.boulder.ibm.com/cgi-bin/bookmgr/download/DZ9ZR009.pdf The associated builtins are documented in the GCC manual: http://gcc.gnu.org/onlinedocs/gcc/S_002f390-System-z-Built-in-Functions.html Index: llvm-head/lib/Target/SystemZ/SystemZOperators.td =================================================================== --- llvm-head.orig/lib/Target/SystemZ/SystemZOperators.td +++ llvm-head/lib/Target/SystemZ/SystemZOperators.td @@ -79,6 +79,9 @@ def SDT_ZI32Intrinsic : SDTypeProf def SDT_ZPrefetch : SDTypeProfile<0, 2, [SDTCisVT<0, i32>, SDTCisPtrTy<1>]>;

Default to armv7 cpu for NaCl when march=arm
Summary: When the arch is given as "arm" clang uses the default target CPU from LLVM to determine what the real arch should be (i.e. "arm" becomes "armv4t" because LLVM's getARMCPUForArch falls back to "arm7tdmi"). Default to "cortex-a8" so that we end up with "armv7" in clang. the nacl-direct.c test in clang also covers this case.

This should bring the windows bots back. It is a bit ugly, but it is better than what we had before: The triple would say that the object format was COFF, but llc/llvm-mc would produce an ELF. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@232683 91177308-0d34-0410-b5e6-96231b3b80d8 |

Remove many superfluous SmallString::str() calls.
Now that SmallString is a first-class citizen, most SmallString::str() calls are not required. This patch removes a whole bunch of them, yet there are lots more. There are two use cases where str() is really needed: 1) To use one of StringRef member functions which is not available in SmallString. 2) To convert to std::string, as StringRef implicitly converts while SmallString do not. We may wish to change this, but it may introduce ambiguity. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@232622 91177308-0d34-0410-b5e6-96231b3b80d8 |

Triple: Make setEnvironment not override the object format
Discovered by Halide users who had C++ code like this: Triple.setArch(Triple::x86); Triple.setOS(Triple::Windows); Triple.setObjectFormat(Triple::ELF); Triple.setEnvironment(Triple::MSVC); This would produce the stringified triple of x86-windows-msvc, instead of the x86-windows-msvc-elf string needed to run MCJIT. With this change, they retain the -elf suffix. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@229160 91177308-0d34-0410-b5e6-96231b3b80d8 |

Extend the triple parsing to support this. Avoid running the ARM parser
