Add AArch32 DCPS{1,2,3} and HLT instructions. These were pretty straightforward instructions, with some assembly support required for HLT. The ARM assembler is keen to split the instruction mnemonic into a (non-existent) 'H' instruction with the LT condition code. An exception for HLT is needed. HLT follows the same rules as BKPT when in IT blocks, so the special BKPT hadling code has been adapted to handle HLT also. Regression tests added including diagnostic tests for out of range immediates and illegal condition codes, as well as negative tests for pre-ARMv8. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190053 91177308-0d34-0410-b5e6-96231b3b80d8

ARM: fix assert on unpredictable POP instruction. POP instructions are aliased to the ARM LDM variants but have different syntax. This caused two problems: we tried to access a non-existent operand to annotate the '!', and the error message didn't make much sense.

ARM: provide diagnostics on more writeback LDM/STM instructions The set of circumstances where the writeback register is allowed to be in the list of registers is rather baroque, but I think this implements them all on the assembly parsing side. For disassembly, we still warn about an ARM-mode LDM even if the architecture revision is < v7 (the required architecture information isn't available). It's a silly instruction anyway, so hopefully no-one will mind. rdar://problem/15223374 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193185 91177308-0d34-0410-b5e6-96231b3b80d8

Add support for ARM modified-immediate assembly syntax. Certain ARM instructions accept 32-bit immediate operands encoded as a 8-bit integer value (0-255) and a 4-bit rotation (0-30, even). Current ARM assembly syntax support in LLVM allows the decoded (32-bit) immediate to be specified as a single immediate operand for such instructions: mov r0, #4278190080 The ARMARM defines an extended assembly syntax allowing the encoding to be made more explicit, as in: mov r0, #255, #8 ; (same 32-bit value as above) The behaviour of the two instructions can be different w.r.t flags, which is documented under "Modified immediate constants" in ARMARM. This patch enables support for this extended syntax at the MC layer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@223113 91177308-0d34-0410-b5e6-96231b3b80d8

Fix assembling of Thumb2 branch instructions. The long encoding for Thumb2 unconditional branches is broken. Additionally, there is no range checking for target operands; as such for instructions originating in assembly code, only short Thumb encodings are generated, regardless of the bitsize needed for the offset. Adding range checking is non trivial due to the representation of Thumb branch instructions. There is no true difference between conditional and unconditional branches in terms of operands and syntax - even unconditional branches have a predicate which is expected to match that of the IT block they are in. Yet, the encodings and the permitted size of the offset differ. Due to this, for any mnemonic there are really 4 encodings to choose for. The problem cannot be handled in the parser alone or by manipulating td files. Because the parser builds first a set of match candidates and then checks them one by one, whatever tablegen-only solution might be found will ultimately be dependent of the parser's evaluation order. What's worse is that due to the fact that all branches have the same syntax and the same kinds of operands, that order is governed by the lexicographical ordering of the names of operand classes... To circumvent all this, any necessary disambiguation is added to the instruction validation pass. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188067 91177308-0d34-0410-b5e6-96231b3b80d8

This fixes three issues related to Thumb literal loads: 1. The offset range for Thumb1 PC relative loads is [0..1020] and not [-1024..1020] 2. Thumb2 PC relative loads may define the PC, so the restriction placed on target register is removed 3. Removes unneeded alias between "ldr.n" and t1LDRpci. ".n" is actually stripped by both tablegen and the ASM parser, so this alias rule really does nothing git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188466 91177308-0d34-0410-b5e6-96231b3b80d8

@ CHECK-ERRORS: error: branch target out of range
Fix assembling of Thumb2 branch instructions. The long encoding for Thumb2 unconditional branches is broken. Additionally, there is no range checking for target operands; as such for instructions originating in assembly code, only short Thumb encodings are generated, regardless of the bitsize needed for the offset. Adding range checking is non trivial due to the representation of Thumb branch instructions. There is no true difference between conditional and unconditional branches in terms of operands and syntax - even unconditional branches have a predicate which is expected to match that of the IT block they are in. Yet, the encodings and the permitted size of the offset differ. Due to this, for any mnemonic there are really 4 encodings to choose for. The problem cannot be handled in the parser alone or by manipulating td files. Because the parser builds first a set of match candidates and then checks them one by one, whatever tablegen-only solution might be found will ultimately be dependent of the parser's evaluation order. What's worse is that due to the fact that all branches have the same syntax and the same kinds of operands, that order is governed by the lexicographical ordering of the names of operand classes... To circumvent all this, any necessary disambiguation is added to the instruction validation pass. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188067 91177308-0d34-0410-b5e6-96231b3b80d8

ARM: allow cortex-m0 to use hint instructions The hint instructions ("nop", "yield", etc) are mostly Thumb2-only, but have been ported across to the v6M architecture. Fortunately, v6M seems to sit nicely between v6 (thumb-1 only) and v6T2, so we can add a feature for it fairly easily. rdar://problem/15144406 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192097 91177308-0d34-0410-b5e6-96231b3b80d8

This fixes three issues related to Thumb literal loads: 1. The offset range for Thumb1 PC relative loads is [0..1020] and not [-1024..1020] 2. Thumb2 PC relative loads may define the PC, so the restriction placed on target register is removed 3. Removes unneeded alias between "ldr.n" and t1LDRpci. ".n" is actually stripped by both tablegen and the ASM parser, so this alias rule really does nothing git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188466 91177308-0d34-0410-b5e6-96231b3b80d8
