* [Sparc] Move InstPrinter files to MCTargetDesc. NFCRichard Trieu2019-05-1111-34/+9
| | | | | | | | | For some targets, there is a circular dependency between InstPrinter and MCTargetDesc. Merging them together will fix this. For the other targets, the merging is to maintain consistency so all targets will have the same structure. llvm-svn: 360506
* [AsmPrinter] refactor to support %c w/ GlobalAddress'Nick Desaulniers2019-04-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Targets like ARM, MSP430, PPC, and SystemZ have complex behavior when printing the address of a MachineOperand::MO_GlobalAddress. Move that handling into a new overriden method in each base class. A virtual method was added to the base class for handling the generic case. Refactors a few subclasses to support the target independent %a, %c, and %n. The patch also contains small cleanups for AVRAsmPrinter and SystemZAsmPrinter. It seems that NVPTXTargetLowering is possibly missing some logic to transform GlobalAddressSDNodes for TargetLowering::LowerAsmOperandForConstraint to handle with "i" extended inline assembly asm constraints.

* [AsmPrinter] refactor to remove remove AsmVariant. NFCNick Desaulniers2019-04-101-7/+4
| | | | | | | | | | | | | | | | | | | | | | | | | Summary: The InlineAsm::AsmDialect is only required for X86; no architecture makes use of it and as such it gets passed around between arch-specific and general code while being unused for all architectures but X86. Since the AsmDialect is queried from a MachineInstr, which we also pass around, remove the additional AsmDialect parameter and query for it deep in the X86AsmPrinter only when needed/as late as possible. This refactor should help later planned refactors to AsmPrinter, as this difference in the X86AsmPrinter makes it harder to make AsmPrinter more generic.

* Implementation of asm-goto support in LLVMCraig Topper2019-02-081-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | This patch accompanies the RFC posted here: http://lists.llvm.org/pipermail/llvm-dev/2018-October/127239.html This patch adds a new CallBr IR instruction to support asm-goto inline assembly like gcc as used by the linux kernel. This instruction is both a call instruction and a terminator instruction with multiple successors. Only inline assembly usage is supported today. This also adds a new INLINEASM_BR opcode to SelectionDAG and MachineIR to represent an INLINEASM block that is also considered a terminator instruction. There will likely be more bug fixes and optimizations to follow this, but we felt it had reached a point where we would like to switch to an incremental development model.

* Update the file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-1956-224/+168
| | | | | | | | | | | | | | | | | to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636

* [Sparc] Use float register for integer constrained with "f" in inline asmDaniel Cederman2018-12-131-8/+8
| | | | | | | | | | | | | | | | | | | | | | Summary: Constraining an integer value to a floating point register using "f" causes an llvm_unreachable to trigger. This patch allows i32 integers to be placed in a single precision float register and i64 integers to be placed in a double precision float register. This matches the behavior of GCC. For other types the llvm_unreachable is removed to instead trigger an error message that points out the offending line.

| | | | | | | | | | | | | | | | | | | | | | Summary: Currently bitcasting constants from f64 to v2i32 is done by storing the value to the stack and then loading it again. This is not necessary, but seems to happen because v2i32 is a valid type for Sparc V8. If it had not been legal, we would have gotten help from the type legalizer.

| | | | | | | | | | | | | | | | | | On targets like Arm some relaxations may only be performed when certain architectural features are available. As functions can be compiled with differing levels of architectural support we must make a judgement on whether we can relax based on the MCSubtargetInfo for the function. This change passes through the MCSubtargetInfo for the function to fixupNeedsRelaxation so that the decision on whether to relax can be made per function. In this patch, only the ARM backend makes use of this information. We must also pass the MCSubtargetInfo to applyFixup because some fixups skip error checking on the assumption that relaxation has occurred, to prevent code-generation errors applyFixup must see the same MCSubtargetInfo as fixupNeedsRelaxation.
