* [Layering] Move DebugInfo.h into the IR library where its implementationChandler Carruth2014-03-061-1/+1
| | | | | | already lives. llvm-svn: 203046
* Always print the implicit .text at the start of an asm file.Rafael Espindola2014-03-051-1/+1
| | | | | | | | | | | | | | | | | Before llvm-mc would print it, but llc was assuming that it would produce another section changing directive before one was needed. That assumption is false with inline asm. Fixes PR19049. Another option would be to always create the section, but in the asm printer avoid printing sections changes during initialization. That would work, but * We do use the fact that llvm-mc prints it in testing. The tests can be changed if needed. * A quick poll on IRC suggest that most developers prefer the implicit .text to be printed. llvm-svn: 203001

* move getNameWithPrefix and getSymbol to TargetMachine.Rafael Espindola2014-02-191-2/+2
| | | | | | | | | | TargetLoweringBase is implemented in CodeGen, so before this patch we had a dependency fom Target to CodeGen. This would show up as a link failure of llvm-stress when building with -DBUILD_SHARED_LIBS=ON. This fixes pr18900. llvm-svn: 201711
* Add back r201608, r201622, r201624 and r201625Rafael Espindola2014-02-191-4/+11
| | | | | | | | | | | | | | r201608 made llvm corretly handle private globals with MachO. r201622 fixed a bug in it and r201624 and r201625 were changes for using private linkage, assuming that llvm would do the right thing. They all got reverted because r201608 introduced a crash in LTO. This patch includes a fix for that. The issue was that TargetLoweringObjectFile now has to be initialized before we can mangle names of private globals. This is trivially true during the normal codegen pipeline (the asm printer does it), but LTO has to do it manually. llvm-svn: 201700
* Revert r201622 and r201608.Daniel Jasper2014-02-191-11/+4
| | | | | | | This causes the LLVMgold plugin to segfault. More information on the replies to r201608. llvm-svn: 201669
* Fix PR18743.Rafael Espindola2014-02-181-4/+11
| | | | | | | | | | | | | | | | | | | | | | | | The IR @foo = private constant i32 42 is valid, but before this patch we would produce an invalid MachO from it. It was invalid because it would use an L label in a section where the liker needs the labels in order to atomize it. One way of fixing it would be to just reject this IR in the backend, but that would not be very front end friendly. What this patch does is use an 'l' prefix in sections that we know the linker requires symbols for atomizing them. This allows frontends to just use private and not worry about which sections they go to or how the linker handles them. One small issue with this strategy is that now a symbol name depends on the section, which is not available before codegen. This is not a problem in practice. The reason is that it only happens with private linkage, which will be ignored by the non codegen users (llvm-nm and llvm-ar). llvm-svn: 201608

| | | | | | | | | | | | Debug info: Emit values in subregisters that do not have a separate DWARF register number by emitting a super-register + DW_OP_bit_piece. This is necessary because on x86_64, there are no DWARF register numbers for i386-style subregisters. Fixes a bunch of FIXMEs. rdar://problem/16015314 llvm-svn: 201190

* Use a consistent argument order in TargetLoweringObjectFile.Rafael Espindola2014-02-091-2/+2
| | | | | | | | | These methods normally call each other and it is really annoying if the arguments are in different order. The more common rule was that the arguments specific to call are first (GV, Encoding, Suffix) and the auxiliary objects (Mang, TM) come after. This patch changes the exceptions. llvm-svn: 201044
* Pass the Mangler by reference.Rafael Espindola2014-02-081-7/+9
| | | | | | | It is never null and it is not used in casts, so there is no reason to use a pointer. This matches how we pass TM. llvm-svn: 201025

* WinCOFF: Transform IR expressions featuring __ImageBase into image relative ↵David Majnemer2014-01-151-0/+4
| | | | | | | | | | | | | relocations MSVC on x64 requires that we create image relative symbol references to refer to RTTI data. Seeing as how there is no way to explicitly make reference to a given relocation type in LLVM IR, pattern match expressions of the form &foo - &__ImageBase.

* Decouple dllexport/dllimport from linkageNico Rieck2014-01-141-2/+0
| | | | | | | | | | | | | | | | | | | Representing dllexport/dllimport as distinct linkage types prevents using these attributes on templates and inline functions. Instead of introducing further mixed linkage types to include linkonce and weak ODR, the old import/export linkage types are replaced with a new separate visibility-like specifier: define available_externally dllimport void @f() {} @Var = dllexport global i32 1, align 4 Linkage for dllexported globals and functions is now equal to their linkage without dllexport. Imported globals and functions must be either declarations with external linkage, or definitions with AvailableExternallyLinkage. llvm-svn: 199218

* Handle bundled terminators in isBlockOnlyReachableByFallthrough.Jakob Stoklund Olesen2014-01-121-7/+7
| | | | | | | | | | Targets like SPARC and MIPS have delay slots and normally bundle the delay slot instruction with the corresponding terminator. Teach isBlockOnlyReachableByFallthrough to find any MBB operands on bundled terminators so SPARC doesn't need to specialize this function. llvm-svn: 199061
* Put the functionality for printing a value to a raw_ostream as anChandler Carruth2014-01-091-4/+3
| | | | | | | | | | | | operand into the Value interface just like the core print method is. That gives a more conistent organization to the IR printing interfaces -- they are all attached to the IR objects themselves. Also, update all the users. This removes the 'Writer.h' header which contained only a single function declaration. llvm-svn: 198836
* Move the llvm mangler to lib/IR.Rafael Espindola2014-01-071-1/+1
| | | | | | This makes it available to tools that don't link with target (like llvm-ar). llvm-svn: 198708
* Move the LLVM IR asm writer header files into the IR directory, as theyChandler Carruth2014-01-071-1/+1
| | | | | | | | | | | | | | | | | are part of the core IR library in order to support dumping and other basic functionality. Rename the 'Assembly' include directory to 'AsmParser' to match the library name and the only functionality left their -- printing has been in the core IR library for quite some time. Update all of the #includes to match. All of this started because I wanted to have the layering in good shape before I started adding support for printing LLVM IR using the new pass infrastructure, and commandline support for the new pass infrastructure. llvm-svn: 198688
* Make the llvm mangler depend only on DataLayout.Rafael Espindola2014-01-031-6/+11
| | | | | | | | | | | | | | Before this patch any program that wanted to know the final symbol name of a GlobalValue had to link with Target. This patch implements a compromise solution where the mangler uses DataLayout. This way, any tool that already links with Target (llc, clang) gets the exact behavior as before and new IR files can be mangled without linking with Target. With this patch the mangler is constructed with just a DataLayout and DataLayout is extended to include the information the Mangler needs. llvm-svn: 198438
