* Add an -mattr option to the gold plugin to support subtarget features in LTOTom Roeder2014-04-25
| | | | | | | | | | | | This adds support for an -mattr option to the gold plugin and to llvm-lto. This allows the caller to specify details of the subtarget architecture, like +aes, or +ssse3 on x86. Note that this requires a change to the include/llvm-c/lto.h interface: it adds a function lto_codegen_set_attr and it increments the version of the interface. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@207279 91177308-0d34-0410-b5e6-96231b3b80d8

* verify-di: Implement DebugInfoVerifierDuncan P. N. Exon Smith2014-04-15
| | | | | | | | | | | | | | | | | | | | | Implement DebugInfoVerifier, which steals verification relying on DebugInfoFinder from Verifier. - Adds LegacyDebugInfoVerifierPassPass, a ModulePass which wraps DebugInfoVerifier. Uses -verify-di command-line flag. - Change verifyModule() to invoke DebugInfoVerifier as well as Verifier. - Add a call to createDebugInfoVerifierPass() wherever there was a call to createVerifierPass(). This implementation as a module pass should sidestep efficiency issues, allowing us to turn debug info verification back on. <rdar://problem/15500563> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@206300 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | This adds a second implementation of the AArch64 architecture to LLVM, accessible in parallel via the "arm64" triple. The plan over the coming weeks & months is to merge the two into a single backend, during which time thorough code review should naturally occur. Everything will be easier with the target in-tree though, hence this commit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@205090 91177308-0d34-0410-b5e6-96231b3b80d8
* Remove the linker_private and linker_private_weak linkages.Rafael Espindola2014-03-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These linkages were introduced some time ago, but it was never very clear what exactly their semantics were or what they should be used for. Some investigation found these uses: * utf-16 strings in clang. * non-unnamed_addr strings produced by the sanitizers. It turns out they were just working around a more fundamental problem. For some sections a MachO linker needs a symbol in order to split the section into atoms, and llvm had no idea that was the case. I fixed that in r201700 and it is now safe to use the private linkage. When the object ends up in a section that requires symbols, llvm will use a 'l' prefix instead of a 'L' prefix and things just work. With that, these linkages were already dead, but there was a potential future user in the objc metadata information. I am still looking at CGObjcMac.cpp, but at this point I am convinced that linker_private and linker_private_weak are not what they need. The objc uses are currently split in * Regular symbols (no '\01' prefix). LLVM already directly provides whatever semantics they need. * Uses of a private name (start with "\01L" or "\01l") and private linkage. We can drop the "\01L" and "\01l" prefixes as soon as llvm agrees with clang on L being ok or not for a given section. I have two patches in code review for this. * Uses of private name and weak linkage. The last case is the one that one could think would fit one of these linkages. That is not the case. The semantics are * the linker will merge these symbol by *name*. * the linker will hide them in the final DSO. Given that the merging is done by name, any of the private (or internal) linkages would be a bad match. They allow llvm to rename the symbols, and that is really not what we want. From the llvm point of view, these objects should really be (linkonce|weak)(_odr)?. For now, just keeping the "\01l" prefix is probably the best for these symbols. If we one day want to have a more direct support in llvm, IMHO what we should add is not a linkage, it is just a hidden_symbol attribute. It would be applicable to multiple linkages. For example, on weak it would produce the current behavior we have for objc metadata. On internal, it would be equivalent to private (and we should then remove private). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@203866 91177308-0d34-0410-b5e6-96231b3b80d8

* Add 'remark' diagnostic type in LLVMTobias Grosser2014-02-28
| | | | | | | | | | | | A 'remark' is information that is not an error or a warning, but rather some additional information provided to the user. In contrast to a 'note' a 'remark' is an independent diagnostic, whereas a 'note' always depends on another diagnostic. A typical use case for remark nodes is information provided to the user, e.g. information provided by the vectorizer about loops that have been vectorized. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@202474 91177308-0d34-0410-b5e6-96231b3b80d8
* Use DataLayout from the module when easily available.Rafael Espindola2014-02-25
| | | | | | | | | | | | | | | | | Eventually DataLayoutPass should go away, but for now that is the only easy way to get a DataLayout in some APIs. This patch only changes the ones that have easy access to a Module. One interesting issue with sometimes using DataLayoutPass and sometimes fetching it from the Module is that we have to make sure they are equivalent. We can get most of the way there by always constructing the pass with a Module. In fact, the pass could be changed to point to an external DataLayout instead of owning one to make this stricter. Unfortunately, the C api passes a DataLayout, so it has to be up to the caller to make sure the pass and the module are in sync. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@202204 91177308-0d34-0410-b5e6-96231b3b80d8
* Make DataLayout a plain object, not a pass.Rafael Espindola2014-02-25

* Add back r201608, r201622, r201624 and r201625Rafael Espindola2014-02-19
| | | | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201700 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix PR18743.Rafael Espindola2014-02-18
| | | | | | | | | | | | | | | | | | | | | | | | 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). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201608 91177308-0d34-0410-b5e6-96231b3b80d8

The path argument will be passed to makeBuffer to make sure the MemoryBuffer has a name and the created module has a module identifier. This is mainly for emitting warning messages from the linker.

| | | | | | | | | | | | | | | | | | | | Add a hook in the C API of LTO so that clients of the code generator can set their own handler for the LLVM diagnostics. The handler is defined like this: typedef void (*lto_diagnostic_handler_t)(lto_codegen_diagnostic_severity_t severity, const char *diag, void *ctxt) - severity says how bad this is. - diag is a string that contains the diagnostic message. - ctxt is the registered context for this handler.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reapply r199191, reverted in r199197 because it carelessly broke Other/link-opts.ll. The problem was that calling createInternalizePass("main") would select createInternalizePass(bool("main")) instead of createInternalizePass(ArrayRef<const char *>("main")). This commit fixes the bug. The original commit message follows. Add API to LTOCodeGenerator to specify a strategy for the -internalize pass. This is a new attempt at Bill's change in r185882, which he reverted in r188029 due to problems with the gold linker. This puts the onus on the linker to decide whether (and what) to internalize. In particular, running internalize before outputting an object file may change a 'weak' symbol into an internal one, even though that symbol could be needed by an external object file --- e.g., with arclite. This patch enables three strategies: - LTO_INTERNALIZE_FULL: the default (and the old behaviour). - LTO_INTERNALIZE_NONE: skip -internalize. - LTO_INTERNALIZE_HIDDEN: only -internalize symbols with hidden visibility. LTO_INTERNALIZE_FULL should be used when linking an executable. Outputting an object file (e.g., via ld -r) is more complicated, and depends on whether hidden symbols should be internalized. E.g., for ld -r, LTO_INTERNALIZE_NONE can be used when -keep_private_externs, and LTO_INTERNALIZE_HIDDEN can be used otherwise. However, LTO_INTERNALIZE_FULL is inappropriate, since the output object file will eventually need to link with others. lto_codegen_set_internalize_strategy() sets the strategy for subsequent calls to lto_codegen_write_merged_modules() and lto_codegen_compile*(). <rdar://problem/14334895> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199244 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | directory. These passes are already defined in the IR library, and it doesn't make any sense to have the headers in Analysis. Long term, I think there is going to be a much better way to divide these matters. The dominators code should be fully separated into the abstract graph algorithm and have that put in Support where it becomes obvious that evn Clang's CFGBlock's can use it. Then the verifier can manually construct dominance information from the Support-driven interface while the Analysis library can provide a pass which both caches, reconstructs, and supports a nice update API. But those are very long term, and so I don't want to leave the really confusing structure until that day arrives. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199082 91177308-0d34-0410-b5e6-96231b3b80d8

Also comment and sink the include of "Windows.h" in three .inc files to match the usage in Memory.inc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198685 91177308-0d34-0410-b5e6-96231b3b80d8
* Make the llvm mangler depend only on DataLayout.Rafael Espindola2014-01-03
| | | | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198438 91177308-0d34-0410-b5e6-96231b3b80d8
