* Option parsing: remove non-SUPPORT_ALIASARGS fall-backHans Wennborg2013-07-311-14/+2
| | | | | | | | The clients of this code have been updated to all support AliasArgs. This depends on Clang r187538 and lld r187541. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187546 91177308-0d34-0410-b5e6-96231b3b80d8
* Option parsing: add support for alias arguments.Hans Wennborg2013-07-311-3/+30
| | | | | | | | | | | | | | | | | | This makes option aliases more powerful by enabling them to pass along arguments to the option they're aliasing. For example, if we have a joined option "-foo=", we can now specify a flag option "-bar" to be an alias of that, with the argument "baz". This is especially useful for the cl.exe compatible clang driver, where many options are aliases. For example, this patch enables us to alias "/Ox" to "-O3" (-O is a joined option), and "/WX" to "-Werror" (again, -W is a joined option).

We can never match "llvm.nvvm.texsurf.handle.internal" here because it will always be erroneously matched by the first condition.

* lit: Support cancellation on WindowsNico Rieck2013-07-191-0/+21
| | | | | | | | | | | | The current machinery using KeyboardInterrupt for canceling doesn't work with multiple threads on Windows as it just cancels the currently run tests but the runners continue. We install a handler for Ctrl-C which stops the provider from providing any more tests to the runners. Together with aborting all currently running tests, this brings lit to a halt. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186695 91177308-0d34-0410-b5e6-96231b3b80d8

* Add new directive called CHECK-LABEL to FileCheck.Stephen Lin2013-07-121-29/+94
| | | | | | | | | CHECK-LABEL is meant to be used in place on CHECK on lines containing identifiers or other unique labels (they need not actually be labels in the source or output language, though.) This is used to break up the input stream into separate blocks delineated by CHECK-LABEL lines, each of which is checked independently. This greatly improves the accuracy of errors and fix-it hints in many cases, and allows for FileCheck to recover from errors in one block by continuing to subsequent blocks. Some tests will be converted to use this new directive in forthcoming patches. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186162 91177308-0d34-0410-b5e6-96231b3b80d8
* Target/X86: Add explicit Win64 and System V/x86-64 calling conventions.Charles Davis2013-07-121-6/+7
| | | | | | | | | | | | | | | Summary: This patch adds explicit calling convention types for the Win64 and System V/x86-64 ABIs. This allows code to override the default, and use the Win64 convention on a target that wants to use SysV (and vice-versa). This is needed to implement the `ms_abi` and `sysv_abi` GNU attributes.

* Improve the compression of the tablegen DiffLists by introducing a new sortChad Rosier2013-06-272-4/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | algorithm when assigning EnumValues to the synthesized registers. The current algorithm, LessRecord, uses the StringRef compare_numeric function. This function compares strings, while handling embedded numbers. For example, the R600 backend registers are sorted as follows: T1 T1_W T1_X T1_XYZW T1_Y T1_Z T2 T2_W T2_X T2_XYZW T2_Y T2_Z In this example, the 'scaling factor' is dEnum/dN = 6 because T0, T1, T2 have an EnumValue offset of 6 from one another. However, in other parts of the register bank, the scaling factors are different: dEnum/dN = 5: KC0_128_W KC0_128_X KC0_128_XYZW KC0_128_Y KC0_128_Z KC0_129_W KC0_129_X KC0_129_XYZW KC0_129_Y KC0_129_Z The diff lists do not work correctly because different kinds of registers have different 'scaling factors'. This new algorithm, LessRecordRegister, tries to enforce a scaling factor of 1. For example, the registers are now sorted as follows: T1 T2 T3 ... T0_W T1_W T2_W ... T0_X T1_X T2_X ... KC0_128_W KC0_129_W KC0_130_W ... For the Mips and R600 I see a 19% and 6% reduction in size, respectively. I did see a few small regressions, but the differences were on the order of a few bytes (e.g., AArch64 was 16 bytes). I suspect there will be even greater wins for targets with larger register files.

* TableGen: Generate a function for getting operand indices based on their ↵Tom Stellard2013-06-251-0/+130
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | defined names This patch modifies TableGen to generate a function in ${TARGET}GenInstrInfo.inc called getNamedOperandIdx(), which can be used to look up indices for operands based on their names. In order to activate this feature for an instruction, you must set the UseNamedOperandTable bit. For example, if you have an instruction like: def ADD : TargetInstr <(outs GPR:$dst), (ins GPR:$src0, GPR:$src1)>; You can look up the operand indices using the new function, like this: Target::getNamedOperandIdx(Target::ADD, Target::OpName::dst) => 0 Target::getNamedOperandIdx(Target::ADD, Target::OpName::src0) => 1 Target::getNamedOperandIdx(Target::ADD, Target::OpName::src1) => 2 The operand names are case sensitive, so $dst and $DST are considered different operands. This change is useful for R600 which has instructions with a large number of operands, many of which model single bit instruction configuration values. These configuration bits are common across most instructions, but may have a different operand index depending on the instruction type. It is useful to have a convenient way to look up the operand indices, so these bits can be generically set on any instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184879 91177308-0d34-0410-b5e6-96231b3b80d8
