* Add support to read aux vector valuesAntonio Afonso2019-06-113-0/+170
| | | | | | | | | | | | | | | | | | | | Summary: This is the second patch to improve module loading in a series that started here (where I explain the motivation and solution): https://reviews.llvm.org/D62499 I need to read the aux vector to know where the r_debug map with the loaded libraries are. The AuxVector class was made generic so it could be reused between the POSIX-DYLD plugin and NativeProcess*. The class itself ended up in the ProcessUtility plugin.

* [FuncUnwinders] Use "symbol file" unwind plans for unwindingPavel Labath2019-05-241-6/+8
| | | | | | | | | | | | | | | | | Summary: Previous patch (r360409) introduced the "symbol file unwind plan" concept, but that plan wasn't used for unwinding yet. With this patch, we start to consider the new plan as a possible strategy for both synchronous and asynchronous unwinding. I also add a test that asserts that unwinding via breakpad STACK CFI info works end-to-end.

* RegisterContextLLDB: Push CFA value on DWARF stack when evaluating register ↵Pavel Labath2019-05-071-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | expressions Summary: This behavior is specified in the Section 6.4.2.3 (Register Rule instructions) of the DWARF4 spec. We were not doing that, which meant that any register rule which was relying on the cfa value being there was not evaluated correctly (it was aborted due to "out of bounds" access). I'm not sure how come this wasn't noticed before, but I guess this has something to do with the fact that dwarf unwind expressions are not used very often, and when they are, the situation is so complicated that the CFA is of no use. I noticed this when I started emitting dwarf expressions for the unwind information present in breakpad symbol files.

* RegisterContextLLDB::GetFullUnwindPlanForFrame has four verboseJason Molenda2019-05-021-18/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | logging messages that are written the same, making it difficult to know for certain which code path was taken based on a logfile. Add some words to make each unique. Right now the ordering for finding a FullUnwindPlan (ignoring fallback unwind plan logic) is 1. If this is a _sigtramp like function, try eh_frame which is hand written on darwin systems to account for finding the saved register context correctly. 2. Ask the DynamicLoader if eh_frame should be preferred for this frame. Some binaries on the system may have hand-written eh_frame and the DynamicLoader is the source for this. (primarily this is for hand-written assembly in the objc runtime, and we tell lldb to trust that for functions in libobjc.dylib.) 3. if 0th frame, use GetUnwindPlanAtNonCallSite plan. 4. GetUnwindPlanAtCallSite {for 0th or any other} 5. GetUnwindPlanAtNonCallSite {now for non-0th frames, only if not from a compiler? hm.} 6. GetUnwindPlanArchitectureDefaultAtFunctionEntry if we're on the first instruction 7. Architectural default unwind plan ABI::CreateDefaultUnwindPlan I'm moving #6 -- DefaultAtFunctionEntry -- up to between #3 and #4, where we're already doing things specific to the zeroth frame. If we're on the zeroth frame and the GetUnwindPlanAtNonCallSite plan has failed for some reason, and we're on the first instruction, we should definitely use DefaultAtFunctionEntry instead of any other unwind plan. If we're trying to step out of some rando function on the system that we couldn't assembly instruction inspect, this is sufficient for us to step out of it. llvm-svn: 359847
* FuncUnwinders: remove "current_offset" from function argumentsPavel Labath2019-04-231-14/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This argument was added back in 2010 (r118882) to support the ability to unwind from functions whose eh_frame entry does not cover the entire range of the function. However, due to the caching happening in FuncUnwinders, this solution is very fragile. FuncUnwinders will cache the plan it got from eh_frame regardless of the value of the current_offset, so our ability to unwind from a given function depended what was the value of "current_offset" the first time that this function was called. Furthermore, since the "image show-unwind" command did not know what's the right offset to pass, this created an unfortunate situation where "image show-unwind" would show no valid plans for a function, even though they were available and being used. In this patch I implement the feature slightly differently. Instead of giving just a base address to the eh_frame unwinder, I give it the entire range we are interested in. Then, I change the unwinder to return the first plan that covers (even partially) that range. This way even a partial plan will be returned, regardless of the address in the function where we are stopped at. This solution is still not 100% correct, as it will not handle a function which is covered by two independent fde entries. However, I don't expect anybody will write this kind of functions, and this wasn't handled by the previous implementation either. If this is ever needed in the future. The eh_frame unwinder can be extended to return "composite" unwind plans created by merging sevelar fde entries. I also create a test which triggers this scenario. As doing this is virtually impossible without hand-written assembly, the test only works on x86 linux.

* [NFC] Remove ASCII lines from commentsJonas Devlieghere2019-04-1044-126/+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
* Unify random timeouts throughout LLDB and make them configurable.Adrian Prantl2019-04-051-3/+3
| | | | | | | | | | | | | | | | | Since these timeouts guard against catastrophic error in debugserver, I also increased all of them to the maximum value among them. The motivation for this test was the observation that an asanified LLDB would often exhibit seemingly random test failures that could be traced back to debugserver packets getting out of sync. With this path applied I can no longer reproduce the one particular failure mode that I was investigating. rdar://problem/49441261 Differential Revision: https://reviews.llvm.org/D60340 llvm-svn: 357829

| | | | | | | | | | | | | | | | | My apologies for the large patch. With the exception of ConstString.h itself it was entirely produced by sed. ConstString has exactly one const char * data member, so passing a ConstString by reference is not any more efficient than copying it by value. In both cases a single pointer is passed. But passing it by value makes it harder to accidentally return the address of a local object.

* Remove alignment from struct XSAVE altogetherPavel Labath2019-02-151-1/+1
| | | | | | | | | | | | | I reduced the alignment of this struct in r342029 to avoid compiler warnings about under-aligned allocations, but it turns out that this still causes problems with some compilers (see r353778). As I hinted in r342029, I don't believe any special aligment is necessary here (the only reason for that would be if we used some aligned SSE instructions to access this buffer, but I don't see any reason why we should do that), so here I go all the way, and remove the alignment requirements (except the ones naturally imposed by basic types) altogether. llvm-svn: 354125

* Replace 'ap' with 'up' suffix in variable names. (NFC)Jonas Devlieghere2019-02-1315-48/+48
| | | | | | | | | | | | | | | | | 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

* [x86] Fix issues with a realigned stack in MSVC compiled applicationsAleksandr Urakov2018-10-302-53/+97

MSVC maintains two frame pointers (`ebx` and `ebp`) for a realigned stack - one is used for access to function parameters, while another is used for access to locals. To support this the patch: - adds an alternative frame pointer (`ebx`); - considers stack realignment instructions (e.g. `and esp, -32`); - along with CFA (Canonical Frame Address) which point to the position next to the saved return address (or to the first parameter on the stack) introduces AFA (Aligned Frame Address) which points to the position of the stack pointer right after realignment. AFA is used for access to registers saved after the realignment (see the test); Here is an example of the code with the realignment: ``` struct __declspec(align(256)) OverAligned { char c; }; void foo(int foo_arg) { OverAligned oa_foo = { 1 }; auto aaa_foo = 1234; } void bar(int bar_arg) { OverAligned oa_bar = { 2 }; auto aaa_bar = 5678; foo(1111); } int main() { bar(2222); return 0; } ``` and here is the `bar` disassembly: ``` push ebx mov ebx, esp sub esp, 8 and esp, -100h add esp, 4 push ebp mov ebp, [ebx+4] mov [esp+4], ebp mov ebp, esp sub esp, 200h mov byte ptr [ebp-200h], 2 mov dword ptr [ebp-4], 5678 push 1111 ; foo_arg call j_?foo@@YAXH@Z ; foo(int) add esp, 4 mov esp, ebp pop ebp mov esp, ebx pop ebx retn ``` Reviewers: labath, zturner, jasonmolenda, stella.stamenova Reviewed By: jasonmolenda Subscribers: abidh, lldb-commits Tags: #lldb Differential Revision: https://reviews.llvm.org/D53435 llvm-svn: 345577
* Don't type-erase the SymbolContextItem enumeration.Zachary Turner2018-10-252-5/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When we get the `resolve_scope` parameter from the SB API, it's a `uint32_t`. We then pass it through all of LLDB this way, as a uint32. This is unfortunate, because it means the user of an API never actually knows what they're dealing with. We can call it something like `resolve_scope` and have comments saying "this is a value from the `SymbolContextItem` enumeration, but it makes more sense to just have it actually *be* the correct type in the actual C++ type system to begin with. This way the person reading the code just knows what it is. The reason to use integers instead of enumerations for flags is because when you do bitwise operations on enumerations they get promoted to integers, so it makes it tedious to constantly be casting them back to the enumeration types, so I've introduced a macro to make this happen magically. By writing LLDB_MARK_AS_BITMASK_ENUM after defining an enumeration, it will define overloaded operators so that the returned type will be the original enum. This should address all the mechanical issues surrounding using rich enum types directly. This way, we get a better debugger experience, and new users to the codebase can get more easily acquainted with the codebase because their IDE features can help them understand what the types mean.

* Reduce alignment on struct XSAVE, fixing a gcc warningPavel Labath2018-09-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | The warning is about heap-allocating a struct with bigger alignment requirements than the standard heap allocator provides. AFAICT, all uses of the XSAVE struct are already heap-allocated, so this high alignment does not actually have any effect and removing it should be NFC. I have also done some digging in the commit history. This alignment requirement was since the XSAVE struct was introduced in r180572 when adding AVX register support for linux. It does not mention the alignment specifically, so I am guessing this was just put there because the corresponging XSAVE cpu instruction requires its buffer to be 64-byte aligned. However, LLDB will not be normally reading this struct via the XSAVE instruction directly. Instead we will ask the kernel to copy the buffer saved when suspeding the inferior. This should not require such strict alignment (in fact, linux kernel will happily do this for any alignment). llvm-svn: 342029

The reason for that was that ObjectFileMachO depended on RegisterContextDarwin_arm(64)? (presumably for core file parsing) and the two Register Context classes uses constants from the system headers (KERN_SUCCESS, KERN_INVALID_ARGUMENT). As far as I can tell, these two files don't actually interact with the darwin kernel -- they are used only in ObjectFileMachO and MacOSX-Kernel process plugin (even though it has "kernel" in the name, this one communicates with it via network packets and not syscalls). For the time being I have created OS-independent definitions of these constants and made the register context classes use those. Long term, the error handling in these classes should be probably changed to use more standard mechanisms such as Status or Error classes. This is the only change necessary (apart from build system glue) to make ObjectFileMachO work on other platforms. To demonstrate that, I remove REQUIRES:darwin from our (only) cross-platform mach-o test.

* Enable AUTOBRIEF in doxygen configuration.Adrian Prantl2018-05-022-4/+4
| | | | | | | | | | | | | | This brings the LLDB configuration closer to LLVM's and removes visual clutter in the source code by removing the @brief commands from comments. This patch also reflows the paragraphs in all doxygen comments. See also https://reviews.llvm.org/D46290. Differential Revision: https://reviews.llvm.org/D46321 llvm-svn: 331373
* Reflow paragraphs in comments.Adrian Prantl2018-04-3018-394/+293
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is intended as a clean up after the big clang-format commit (r280751), which unfortunately resulted in many of the comment paragraphs in LLDB being very hard to read. FYI, the script I used was: import textwrap import commands import os import sys import re tmp = "%s.tmp"%sys.argv[1] out = open(tmp, "w+") with open(sys.argv[1], "r") as f: header = "" text = "" comment = re.compile(r'^( *//) ([^ ].*)$') special = re.compile(r'^((([A-Z]+[: ])|([0-9]+ )).*)|(.*;)$') for line in f: match = comment.match(line) if match and not special.match(match.group(2)): # skip intentionally short comments. if not text and len(match.group(2)) < 40: out.write(line) continue if text: text += " " + match.group(2) else: header = match.group(1) text = match.group(2) continue if text: filled = textwrap.wrap(text, width=(78-len(header)), break_long_words=False) for l in filled: out.write(header+" "+l+'\n') text = "" out.write(line) os.rename(tmp, sys.argv[1]) Differential Revision: https://reviews.llvm.org/D46144 llvm-svn: 331197
* Move Args::StringTo*** functions to a new OptionArgParser classPavel Labath2018-04-101-1/+3
| | | | | | | | | | | | | | | | Summary: The idea behind this is to move the functionality which depend on other lldb classes into a separate class. This way, the Args class can be turned into a lightweight arc+argv wrapper and moved into the lower lldb layers.

* Reduce x86 register context boilerplate.Pavel Labath2017-12-184-33/+30
| | | | | | | | | | | | | | | | | | | | | | Summary: The x86 FPR struct was defined as a struct containing a union between two members: XSAVE and FXSAVE. This patch makes FPR a union directly to remove one layer of indirection when trying to access the members. The initial layout of these two structs is identical, which is recognised by the fact that XSAVE has FXSAVE as its first member, so we also considered removing one more layer and leave FPR identical to XSAVE struct, but stopped short of doing that, as the FPR may be used to store different layouts in the future (e.g., ones generated by the FSAVE instruction).
