2018-01-03Thread MCSubtargetInfo through Target::createMCAsmBackendAlex Bradbury
Currently it's not possible to access MCSubtargetInfo from a TgtMCAsmBackend. D20830 threaded an MCSubtargetInfo reference through MCAsmBackend::relaxInstruction, but this isn't the only function that would benefit from access. This patch removes the Triple and CPUString arguments from createMCAsmBackend and replaces them with MCSubtargetInfo. This patch just changes the interface without making any intentional functional changes. Once in, several cleanups are possible: * Get rid of the awkward MCSubtargetInfo handling in ARMAsmBackend * Support 16-bit instructions when valid in MipsAsmBackend::writeNopData * Get rid of the CPU string parsing in X86AsmBackend and just use a SubtargetFeature for HasNopl * Emit 16-bit nops in RISCVAsmBackend::writeNopData if the compressed instruction set extension is enabled (see D41221) This change initially exposed PR35686, which has since been resolved in r321026.

2017-08-02Don't pass the code model to MCRafael Espindola
I was surprised to see the code model being passed to MC. After all, it assembles code, it doesn't create it. The one place it is used is in the expansion of .cfi directives to handle .eh_frame being more that 2gb away from the code. As far as I can tell, gnu assembler doesn't even have an option to enable this. Compiling a c file with gcc -mcmodel=large produces a regular looking .eh_frame. This is probably because in practice linker parse and recreate .eh_frames. In llvm this is used because the JIT can place the code and .eh_frame very far apart. Ideally we would fix the jit and delete this option. This is hard. Apart from confusion another problem with the current interface is that most callers pass CodeModel::Default, which is bad since MC has no way to map it to the target default if it actually needed to. This patch then replaces the argument with a boolean with a default value. The vast majority of users don't ever need to look at it. In fact, only CodeGen and llvm-mc use it and llvm-mc just to enable more testing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@309884 91177308-0d34-0410-b5e6-96231b3b80d8
2017-06-09sink DebugCompressionType into MC for exposing to clangSaleem Abdulrasool
This is a preparatory change to expose the debug compression style to clang. It requires exposing the enumeration and passing the actual value through to the backend from the frontend in actual value form rather than a boolean that selects the GNU style of debug info compression. Minor tweak to the ELF Object Writer to use a variable for re-used values. Add an assertion that debug information format is one of the two currently known types if debug information is being compressed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@305038 91177308-0d34-0410-b5e6-96231b3b80d8

2016-08-08[mips][ias] Fix all the hacks related to MIPS-specific unary operators ↵Daniel Sanders
(%hi/%lo/%gp_rel/etc.). Summary: They are now lexed as a single token on targets where MCAsmInfo::HasMipsExpressions is true and then parsed in a similar way to the '~' operator as part of MCExpr::parseExpression. As a result: * expressions and immediates no longer have different parsing rules. The difference is now solely down to whether evaluateAsAbsolute() succeeds. * %hi(%neg(%gp_rel(x))) are no longer parsed as a single operator and decomposed into the three MipsMCExpr nodes. They are parsed directly as three MipsMCExpr nodes. * parseMemOperand no longer needs to eat all the surrounding parenthesis to get at the outermost operator to make this work * %hi(%neg(%gp_rel(x))) and %lo(%neg(%gp_rel(x))) are no longer the only 3-in-1 relocs that parse for N64. They're still the only combinations that are permitted in relocatable expressions though. Fixing that should be a later patch. * We no longer need to list all the tokens that can occur as the first token of an expression or immediate. test/MC/Mips/expr1.s: This change also prevents the incorrect lowering of %lo(2*4)+foo to %lo(8+foo) which is not an equivalent expression (the difference is whether foo is truncated to 16-bit or not) and the test has been updated to account for the macro expansion the correct expression requires.

2016-03-22MC: Don't access the filesystem in MCContext's constructorJustin Bogner
MCContext shouldn't be accessing the filesystem - that's a gross layering violation and makes it awkward to use as a library or in a daemon where it may not even be allowed filesystem access. The CWD lookup here is normally redundant anyway, since the calling context either also looks up the CWD or sets this to something more specific. Here, we fix up the one caller that doesn't already set up a debug compilation dir and make it clear that the responsibility for such set up is in the users of MCContext. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@264109 91177308-0d34-0410-b5e6-96231b3b80d8

2015-12-21[MC, COFF] Support link /incremental conditionallyDavid Majnemer
Today, we always take into account the possibility that object files produced by MC may be consumed by an incremental linker. This results in us initialing fields which vary with time (TimeDateStamp) which harms hermetic builds (e.g. verifying a self-host went well) and produces sub-optimal code because we cannot assume anything about the relative position of functions within a section (call sites can get redirected through incremental linker thunks). Let's provide an MCTargetOption which controls this behavior so that we can disable this functionality if we know a-priori that the build will not rely on /incremental. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@256203 91177308-0d34-0410-b5e6-96231b3b80d8

form. Summary: GetTarget() may modify TripleName without also updating TheTriple. This can lead to situations where the MCObjectStreamer has a different triple to the rest of LLVM. This inconsistency caused sparc-little-endian.s to pass on Windows because most of LLVM had sparcel-pc-win32 while MCObjectStreamer had "". I believe the same kind of thing was also true of Darwin.

2015-06-15Replace string GNU Triples with llvm::Triple in InitMCObjectFileInfo. NFC.Daniel Sanders
Summary: This affects other tools so the previous C++ API has been retained as a deprecated function for the moment. Clang has been updated with a trivial patch (not covered by the pre-commit review) to avoid breaking -Werror builds. Other in-tree tools will be fixed with similar trivial patches. This continues the patch series to eliminate StringRef forms of GNU triples from the internals of LLVM that began in r239036.

2015-04-20Add targets to cmake for specific target components.Pete Cooper
This adds the following targets to cmake. These can be used to build and link only specific parts of a backend, instead of having to link the whole backend. - AllTargetsAsmPrinters, AllTargetsAsmParsers, AllTargetsDescs, AllTargetsDisassemblers, AllTargetsInfos A typical use for these is instead of linking ${LLVM_TARGETS_TO_BUILD}. This commit changes llvm-mc to show how to use the new targets. Reviewed by Chris Bieneman. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@235324 91177308-0d34-0410-b5e6-96231b3b80d8

2015-04-09Simplify use of formatted_raw_ostream.Rafael Espindola
formatted_raw_ostream is a wrapper over another stream to add column and line number tracking. It is used only for asm printing. This patch moves the its creation down to where we know we are printing assembly. This has the following advantages: * Simpler lifetime management: std::unique_ptr * We don't compute column and line number of object files :-) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@234535 91177308-0d34-0410-b5e6-96231b3b80d8
