This is the first step to fix pr17918. It extends the .section directive a bit, inspired by what the ELF one looks like. The problem with using linkonce is that given .section foo .linkonce.... .section foo .linkonce we would already have switched sections when getting to .linkonce. The cleanest solution seems to be to add the comdat information in the .section itself. ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_34@195822 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | | This change is incorrect. If you delete virtual destructor of both a base class and a subclass, then the following code: Base *foo = new Child(); delete foo; will not cause the destructor for members of Child class. As a result, I observe plently of memory leaks.

| * Remove AllowQuotesInName and friends from MCAsmInfo.Rafael Espindola2013-11-131-21/+0
| | | | | | | | | | | | | | | | | | | | | | Accepting quotes is a property of an assembler, not of an object file. For example, ELF can support any names for sections and symbols, but the gnu assembler only accepts quotes in some contexts and llvm-mc in a few more. LLVM should not produce different symbols based on a guess about which assembler will be reading the code it is printing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194575 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit allows the ARM integrated assembler to parse and assemble the code with .eabi_attribute, .cpu, and .fpu directives. To implement the feature, this commit moves the code from AttrEmitter to ARMTargetStreamers, and several new test cases related to cortex-m4, cortex-r5, and cortex-a15 are added. Besides, this commit also change the Subtarget->isFPOnlySP() to Subtarget->hasD16() to match the usage of .fpu directive. This commit changes the test cases: * Several .eabi_attribute directives in 2010-09-29-mc-asm-header-test.ll are removed because the .fpu directive already cover the functionality. * In the Cortex-A15 test case, the value for Tag_Advanced_SIMD_arch has be changed from 1 to 2, which is more precise. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193524 91177308-0d34-0410-b5e6-96231b3b80d8

| * MC asm parser: allow ?'s in symbol names, and handle @'s in names in MS asmHans Wennborg2013-10-181-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is another (final?) stab at making us able to parse our own asm output on Windows. Symbols on Windows often contain @'s and ?'s in their names. Our asm parser didn't like this. ?'s were not allowed, and @'s were intepreted as trying to reference PLT/GOT/etc. We can't just add quotes around the bad names, since e.g. for MinGW, we use gas to assemble, and it doesn't like quotes in some places (notably in .def directives). This commit makes us allow ?'s in symbol names, and @'s in symbol names for MS assembly.

| * Add a MCTargetStreamer interface.Rafael Espindola2013-10-083-43/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes an old FIXME by creating a MCTargetStreamer interface and moving the target specific functions for ARM, Mips and PPC to it. The ARM streamer is still declared in a common place because it is used from lib/CodeGen/ARMException.cpp, but the Mips and PPC are completely hidden in the corresponding Target directories. I will send an email to llvmdev with instructions on how to use this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192181 91177308-0d34-0410-b5e6-96231b3b80d8

| * Remove some really nasty uses of hasRawTextSupport.Rafael Espindola2013-10-053-44/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When MC was first added, targets could use hasRawTextSupport to keep features working before they were added to the MC interface. The design goal of MC is to provide an uniform api for printing assembly and object files. Short of relaxations and other corner cases, a object file is just another representation of the assembly. It was never the intention that targets would keep doing things like if (hasRawTextSupport()) Set flags in one way. else Set flags in another way. When they do that they create two code paths and the object file is no longer just another representation of the assembly. This also then requires testing with llc -filetype=obj, which is extremelly brittle. This patch removes some of these hacks by replacing them with smaller ones. The ARM flag setting is trivial, so I just moved it to the constructor. For Mips, the patch adds two temporary hack directives that allow the assembly to represent the same things as the object file was already able to. The hope is that the mips developers will replace the hack directives with the same ones that gas uses and drop the -print-hack-directives flag. I will also try to implement a target streamer interface, so that we can move this out of the common code. In summary, for any new work, two rules of the thumb are * Don't use "llc -filetype=obj" in tests. * Don't add calls to hasRawTextSupport. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192035 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch handles LLVM standalone assembler (llvm-mc) ELF flag setting based on input file directive processing. Mips assembly requires processing inline directives that directly and indirectly affect the output ELF header flags. This patch handles one ".abicalls". To process these directives we are following the model the code generator uses by storing state in a container as we go through processing and when we detect the end of input file processing, AsmParser is notified and we update the ELF header flags through a MipsELFStreamer method with a call from MCTargetAsmParser::emitEndOfAsmFile(MCStreamer &OutStreamer). This patch will allow other targets the same functionality. Jack git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191982 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The binutils assembler supports a mode called DOLLAR_DOT which treats the dollar sign token as a reference to the current program counter if the dollar sign doesn't precede a constant or identifier. This commit adds a new MCAsmInfo flag stating whether or not a given target supports this interpretation of the dollar sign token; by default, this flag is not enabled. Further, enable this flag for PPC. The system assembler for AIX and binutils both support using the dollar sign in this manner.

| * Explicitly request unsigned enum types when desiredReid Kleckner2013-09-232-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The underlying type of all plain enums in MSVC is 'int', even if the enumerator contains large 32-bit unsigned values or values greater than UINT_MAX. The only way to get a large or unsigned enum type is to request it explicitly with the C++11 strong enum types feature. However, since LLVM isn't C++11 yet, I had to add a conditional LLVM_ENUM_INT_TYPE to Compiler.h to control its usage. The motivating true positive for this change is compiling PointerIntPair with MSVC for win64. The PointerIntMask value is supposed to be pointer sized value of all ones with some low zeros. Instead, it's truncated to 32-bits! We are only saved later because it is sign extended back in the AND with int64_t, and we happen to want all ones. This silences lots of -Wmicrosoft warnings during a clang self-host targeting Windows. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191241 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | InitMCProcessorInfo right after detecting them. Instead add a new function that only updates the scheduling model and call that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190919 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | got lost during my iterations of review. Thanks to Hal for spotting it! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190604 91177308-0d34-0410-b5e6-96231b3b80d8
| * Add an instruction deprecation feature to TableGen.Joey Gouly2013-09-121-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 'Deprecated' class allows you to specify a SubtargetFeature that the instruction is deprecated on. The 'ComplexDeprecationPredicate' class allows you to define a custom predicate that is called to check for deprecation. For example: ComplexDeprecationPredicate<"MCR"> would mean you would have to define the following function: bool getMCRDeprecationInfo(MCInst &MI, MCSubtargetInfo &STI, std::string &Info) Which returns 'false' for not deprecated, and 'true' for deprecated and store the warning message in 'Info'. The MCTargetAsmParser constructor was chaned to take an extra argument of the MCInstrInfo class, so out-of-tree targets will need to be changed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190598 91177308-0d34-0410-b5e6-96231b3b80d8
