* Have ABI plugins vend llvm MCRegisterInfo dataPavel Labath2019-09-251-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: I was recently surprised to learn that there is a total of 2 (two) users of the register info definitions contained in the ABI plugins. Yet, the defitions themselves span nearly 10kLOC. The two users are: - dwarf expression pretty printer - the mechanism for augmenting the register info definitions obtained over gdb-remote protocol (AugmentRegisterInfoViaABI) Both of these uses need the DWARF an EH register numbers, which is information that is already available in LLVM. This patch makes it possible to do so. It adds a GetMCRegisterInfo method to the ABI class, which every class is expected to implement. Normally, it should be sufficient to obtain the definitions from the appropriate llvm::Target object (for which I provide a utility function), but the subclasses are free to construct it in any way they deem fit. We should be able to always get the MCRegisterInfo object from llvm, with one important exception: if the relevant llvm target was disabled at compile time. To handle this, I add a mechanism to disable the compilation of ABI plugins based on the value of LLVM_TARGETS_TO_BUILD cmake setting. This ensures all our existing are able to create their MCRegisterInfo objects. The new MCRegisterInfo api is not used yet, but the intention is to make use of it in follow-up patches.

* Support Linux signal return trampolines in frame initializationJoseph Tremoulet2019-07-191-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Add __kernel_rt_sigreturn to the list of trap handlers for Linux (it's used as such on aarch64 at least), and __restore_rt as well (used on x86_64). Skip decrement-and-recompute for trap handlers in InitializeNonZerothFrame, as signal dispatch may point the child frame's return address to the start of the return trampoline. Parse the 'S' flag for signal handlers from eh_frame augmentation, and propagate it to the unwind plan.

* [NFC] Remove ASCII lines from commentsJonas Devlieghere2019-04-101-4/+0
| | | | | | | | | | | | | | | | | | | | | | | A lot of comments in LLDB are surrounded by an ASCII line to delimit the begging and end of the comment. Its use is not really consistent across the code base, sometimes the lines are longer, sometimes they are shorter and sometimes they are omitted. Furthermore, it looks kind of weird with the 80 column limit, where the comment actually extends past the line, but not by much. Furthermore, when /// is used for Doxygen comments, it looks particularly odd. And when // is used, it incorrectly gives the impression that it's actually a Doxygen comment. I assume these lines were added to improve distinguishing between comments and code. However, given that todays editors and IDEs do a great job at highlighting comments, I think it's worth to drop this for the sake of consistency. The alternative is fixing all the inconsistencies, which would create a lot more churn. Differential revision: https://reviews.llvm.org/D60508 llvm-svn: 358135
* Replace 'ap' with 'up' suffix in variable names. (NFC)Jonas Devlieghere2019-02-131-6/+6
| | | | | | | | | | | | | | | | | The `ap` suffix is a remnant of lldb's former use of auto pointers, before they got deprecated. Although all their uses were replaced by unique pointers, some variables still carried the suffix. In r353795 I removed another auto_ptr remnant, namely redundant calls to ::get for unique_pointers. Jim justly noted that this is a good opportunity to clean up the variable names as well. I went over all the changes to ensure my find-and-replace didn't have any undesired side-effects. I hope I didn't miss any, but if you end up at this commit doing a git blame on a weirdly named variable, please know that the change was unintentional. llvm-svn: 353912
* Update the file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-191-4/+3
| | | | | | | | | | | | | | | | | 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

* Make CompilerType::getBitSize() / getByteSize() return an optional result. NFCAdrian Prantl2019-01-151-13/+19
| | | | | | | | | | | | | | | | | | | | | | | The code in LLDB assumes that CompilerType and friends use the size 0 as a sentinel value to signal an error. This works for C++, where no zero-sized type exists, but in many other programming languages (including I believe C) types of size zero are possible and even common. This is a particular pain point in swift-lldb, where extra code exists to double-check that a type is *really* of size zero and not an error at various locations. To remedy this situation, this patch starts by converting CompilerType::getBitSize() and getByteSize() to return an optional result. To avoid wasting space, I hand-rolled my own optional data type assuming that no type is larger than what fits into 63 bits. Follow-up patches would make similar changes to the ValueObject hierarchy. rdar://problem/47178964 Differential Revision: https://reviews.llvm.org/D56688 llvm-svn: 351214

* Change the ABI class to have a weak pointer to its Process;Jason Molenda2017-06-291-14/+11
| | | | | | | | | | | | | | | | some methods in the ABI need a Process to do their work. Instead of passing it in as a one-off argument to those methods, this patch puts it in the base class and the methods can retrieve if it needed. Note that ABI's are sometimes built without a Process (e.g. SBTarget::GetStackRedZoneSize) so it's entirely possible that the process weak pointer will not be able to reconsistitue into a strong pointer. <rdar://problem/32526754> llvm-svn: 306633
* Rename Error -> Status.Zachary Turner2017-05-121-7/+7
| | | | | | | | | | | | | | | This renames the LLDB error class to Status, as discussed on the lldb-dev mailing list. A change of this magnitude cannot easily be done without find and replace, but that has potential to catch unwanted occurrences of common strings such as "Error". Every effort was made to find all the obvious things such as the word "Error" appearing in a string, etc, but it's possible there are still some lingering occurences left around. Hopefully nothing too serious. llvm-svn: 302872

| | | | | | | | | | | | | | | | | | | | | | | This moves the following classes from Core -> Utility. ConstString Error RegularExpression Stream StreamString The goal here is to get lldbUtility into a state where it has no dependendencies except on itself and LLVM, so it can be the starting point at which to start untangling LLDB's dependencies. These are all low level and very widely used classes, and previously lldbUtility had dependencies up to lldbCore in order to use these classes. So moving then down to lldbUtility makes sense from both the short term and long term perspective in solving this problem. Differential Revision: https://reviews.llvm.org/D29427 llvm-svn: 293941
* *** This commit represents a complete reformatting of the LLDB source codeKate Stone2016-09-061-836/+1928
| | | | | | | | | | | | | | | | | | | | | | | *** to conform to clang-format’s LLVM style. This kind of mass change has *** two obvious implications: Firstly, merging this particular commit into a downstream fork may be a huge effort. Alternatively, it may be worth merging all changes up to this commit, performing the same reformatting operation locally, and then discarding the merge for this particular commit. The commands used to accomplish this reformatting were as follows (with current working directory as the root of the repository): find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} + find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ; The version of clang-format used was 3.9.0, and autopep8 was 1.2.4. Secondly, “blame” style tools will generally point to this commit instead of a meaningful prior commit. There are alternatives available that will attempt to look through this change and find the appropriate prior commit. YMMV. llvm-svn: 280751

* Made templates that have Enumeration values as arguments work correctly.Greg Clayton2016-06-241-3/+3
| | | | | | | | | | We were checking for integer types only before this. So I added the ability for CompilerType objects to check for integer and enum types. Then I searched for places that were using the CompilerType::IsIntegerType(...) function. Many of these places also wanted to be checking for enumeration types as well, so I have fixed those places. These are in the ABI plug-ins where we are figuring out which arguments would go in where in regisers/stack when making a function call, or determining where the return value would live. The real fix for this is to use clang to compiler a CGFunctionInfo and then modify the code to be able to take the IR and a calling convention and have the backend answer the questions correctly for us so we don't need to create a really bad copy of the ABI in each plug-in, but that is beyond the scope of this bug fix. Also added a test case to ensure this doesn't regress in the future. llvm-svn: 273750

* Clean up register naming conventions inside lldb. Jason Molenda2015-09-151-84/+84
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "gcc" register numbers are now correctly referred to as "ehframe" register numbers. In almost all cases, ehframe and dwarf register numbers are identical (the one exception is i386 darwin where ehframe regnums were incorrect). The old "gdb" register numbers, which I incorrectly thought were stabs register numbers, are now referred to as "Process Plugin" register numbers. This is the register numbering scheme that the remote process controller stub (lldb-server, gdbserver, core file support, kdp server, remote jtag devices, etc) uses to refer to the registers. The process plugin register numbers may not be contiguous - there are remote jtag devices that have gaps in their register numbering schemes. I removed all of the enums for "gdb" register numbers that we had in lldb - these were meaningless - and I put LLDB_INVALID_REGNUM in all of the register tables for the Process Plugin regnum slot. This change is almost entirely mechnical; the one actual change in here is to ProcessGDBRemote.cpp's ParseRegisters() which parses the qXfer:features:read:target.xml response. As it parses register definitions from the xml, it will assign sequential numbers as the eRegisterKindLLDB numbers (the lldb register numberings must be sequential, without any gaps) and if the xml file specifies register numbers, those will be used as the eRegisterKindProcessPlugin register numbers (and those may have gaps). A J-Link jtag device's target.xml does contain a gap in register numbers, and it only specifies the register numbers for the registers after that gap. The device supports many different ARM boards and probably selects different part of its register file as appropriate. http://reviews.llvm.org/D12791 <rdar://problem/22623262> llvm-svn: 247741

* Final bit of type system cleanup that abstracts declaration contexts into ↵Greg Clayton2015-08-241-3/+3
| | | | | | | | | | | | | | | | | | | | lldb_private::CompilerDeclContext and renames ClangType to CompilerType in many accessors and functions. Create a new "lldb_private::CompilerDeclContext" class that will replace all direct uses of "clang::DeclContext" when used in compiler agnostic code, yet still allow for conversion to clang::DeclContext subclasses by clang specific code. This completes the abstraction of type parsing by removing all "clang::" references from the SymbolFileDWARF. The new "lldb_private::CompilerDeclContext" class abstracts decl contexts found in compiler type systems so they can be used in internal API calls. The TypeSystem is required to support CompilerDeclContexts with new pure virtual functions that start with "DeclContext" in the member function names. Converted all code that used lldb_private::ClangNamespaceDecl over to use the new CompilerDeclContext class and removed the ClangNamespaceDecl.cpp and ClangNamespaceDecl.h files. Removed direct use of clang APIs from SBType and now use the abstract type systems to correctly explore types. Bulk renames for things that used to return a ClangASTType which is now CompilerType: "Type::GetClangFullType()" to "Type::GetFullCompilerType()" "Type::GetClangLayoutType()" to "Type::GetLayoutCompilerType()" "Type::GetClangForwardType()" to "Type::GetForwardCompilerType()" "Value::GetClangType()" to "Value::GetCompilerType()" "Value::SetClangType (const CompilerType &)" to "Value::SetCompilerType (const CompilerType &)" "ValueObject::GetClangType ()" to "ValueObject::GetCompilerType()" many more renames that are similar. llvm-svn: 245905
* A messy bit of cleanup: Move towards more descriptive namesJason Molenda2015-08-151-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | for eh_frame and stabs register numberings. This is not complete but it's a step in the right direction. It's almost entirely mechanical. lldb informally uses "gcc register numbering" to mean eh_frame. Why? Probably because there's a notorious bug with gcc on i386 darwin where the register numbers in eh_frame were incorrect. In all other cases, eh_frame register numbering is identical to dwarf. lldb informally uses "gdb register numbering" to mean stabs. There are no official definitions of stabs register numbers for different architectures, so the implementations of gdb and gcc are the de facto reference source. There were some incorrect uses of these register number types in lldb already. I fixed the ones that I saw as I made this change. This commit changes all references to "gcc" and "gdb" register numbers in lldb to "eh_frame" and "stabs" to make it clear what is actually being represented. lldb cannot parse the stabs debug format, and given that no one is using stabs any more, it is unlikely that it ever will. A more comprehensive cleanup would remove the stabs register numbers altogether - it's unnecessary cruft / complication to all of our register structures. In ProcessGDBRemote, when we get register definitions from the gdb-remote stub, we expect to see "gcc:" (qRegisterInfo) or "gcc_regnum" (qXfer:features:read: packet to get xml payload). This patch changes ProcessGDBRemote to also accept "ehframe:" and "ehframe_regnum" from these remotes. I did not change GDBRemoteCommunicationServerLLGS or debugserver to send these new packets. I don't know what kind of interoperability constraints we might be working under. At some point in the future we should transition to using the more descriptive names. Throughout lldb we're still using enum names like "gcc_r0" and "gdb_r0", for eh_frame and stabs register numberings. These should be cleaned up eventually too. The sources link cleanly on macosx native with xcode build. I don't think we'll see problems on other platforms but please let me know if I broke anyone. llvm-svn: 245141

There were a lot of places where we would pass around a raw clang_type_t and also pass along a clang::ASTContext separately. This left room for error. This checkin change all type code over to use ClangASTType everywhere and I cleaned up the interfaces quite a bit. Any code that was in ClangASTContext that was type related, was moved over into ClangASTType. All code that used these types was switched over to use all of the new goodness. llvm-svn: 186130

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | <rdar://problem/13594769> Main changes in this patch include: - cleanup plug-in interface and use ConstStrings for plug-in names - Modfiied the BSD Archive plug-in to be able to pick out the correct .o file when .a files contain multiple .o files with the same name by using the timestamp - Modified SymbolFileDWARFDebugMap to properly verify the timestamp on .o files it loads to ensure we don't load updated .o files and cause problems when debugging The plug-in interface changes: Modified the lldb_private::PluginInterface class that all plug-ins inherit from: Changed: virtual const char * GetPluginName() = 0; To: virtual ConstString GetPluginName() = 0; Removed: virtual const char * GetShortPluginName() = 0; - Fixed up all plug-in to adhere to the new interface and to return lldb_private::ConstString values for the plug-in names. - Fixed all plug-ins to return simple names with no prefixes. Some plug-ins had prefixes and most ones didn't, so now they all don't have prefixed names, just simple names like "linux", "gdb-remote", etc. llvm-svn: 181631

| | | | | | | | | | | | Major fixed to allow reading files that are over 4GB. The main problems were that the DataExtractor was using 32 bit offsets as a data cursor, and since we mmap all of our object files we could run into cases where if we had a very large core file that was over 4GB, we were running into the 4GB boundary. So I defined a new "lldb::offset_t" which should be used for all file offsets. After making this change, I enabled warnings for data loss and for enexpected implicit conversions temporarily and found a ton of things that I fixed. Any functions that take an index internally, should use "size_t" for any indexes and also should return "size_t" for any sizes of collections. llvm-svn: 173463
