| | | | | | | A user request such as: memory read -fc -s10 -c1 *charPtrPtr would cause us to crash upon trying to read 1 char of size 10 from memory This request is now translated into: memory read -fc -s1 -c10 *charPtrPtr (i.e. read 10 chars of size 1 from memory) which is probably also what the user originally wanted llvm-svn: 182398

| | | | | | | | | | | | 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

The validity of the target objects in m_exe_ctx are checked to ensure that any target/process/thread/frame/reg context that are required are valid prior to executing the command. Each command object also contains a Mutex::Locker m_api_locker which gets used if eFlagTryTargetAPILock is set. This centralizes a lot of checking code that was previously and inconsistently implemented across many commands. llvm-svn: 171990

* <rdar://problem/12820334>Greg Clayton2012-12-061-12/+20
| | | | | | | | | | | | | I modified the "Args::StringtoAddress(...)" function to be able to evaluate address expressions. This is now used for any command line arguments or options that takes addresses like: memory read <addr> [<end-addr>] memory write <addr> breakpoint set --address <addr> disassemble --start-address <addr> --end-address <addr> It calls the expression parser to evaluate the address expression and will also work around the issue where the compiler doesn't like to add offsets to function pointers (which is what happens when you try to evaluate "main + 12"). So there is a temp fix in the Args::StringtoAddress() to work around this until we can get special compiler support for debug expressions with function pointers. llvm-svn: 169556

* <rdar://problem/12798131> Greg Clayton2012-12-041-2/+2
| | | | | | | | | | | | Cleaned up the option parsing code to always pass around the short options as integers. Previously we cast this down to "char" and lost some information. I recently added an assert that would detect duplicate short character options which was firing during the test suite. This fix does the following: - make sure all short options are treated as "int" - make sure that short options can be non-printable values when a short option is not required or when an option group is mixed into many commands and a short option is not desired - fix the help printing to "do the right thing" in all cases. Previously if there were duplicate short character options, it would just not emit help for the duplicates - fix option parsing when there are duplicates to parse options correctly. Previously the option parsing, when done for an OptionGroup, would just start parsing options incorrectly by omitting table entries and it would end up setting the wrong option value llvm-svn: 169189

| | | | | | | | | | | | Make breakpoint setting by file and line much more efficient by only looking for inlined breakpoint locations if we are setting a breakpoint in anything but a source implementation file. Implementing this complex for a many reasons. Turns out that parsing compile units lazily had some issues with respect to how we need to do things with DWARF in .o files. So the fixes in the checkin for this makes these changes: - Add a new setting called "target.inline-breakpoint-strategy" which can be set to "never", "always", or "headers". "never" will never try and set any inlined breakpoints (fastest). "always" always looks for inlined breakpoint locations (slowest, but most accurate). "headers", which is the default setting, will only look for inlined breakpoint locations if the breakpoint is set in what are consudered to be header files, which is realy defined as "not in an implementation source file". - modify the breakpoint setting by file and line to check the current "target.inline-breakpoint-strategy" setting and act accordingly - Modify compile units to be able to get their language and other info lazily. This allows us to create compile units from the debug map and not have to fill all of the details in, and then lazily discover this information as we go on debuggging. This is needed to avoid parsing all .o files when setting breakpoints in implementation only files (no inlines). Otherwise we would need to parse the .o file, the object file (mach-o in our case) and the symbol file (DWARF in the object file) just to see what the compile unit was. - modify the "SymbolFileDWARFDebugMap" to subclass lldb_private::Module so that the virtual "GetObjectFile()" and "GetSymbolVendor()" functions can be intercepted when the .o file contenst are later lazilly needed. Prior to this fix, when we first instantiated the "SymbolFileDWARFDebugMap" class, we would also make modules, object files and symbol files for every .o file in the debug map because we needed to fix up the sections in the .o files with information that is in the executable debug map. Now we lazily do this in the DebugMapModule::GetObjectFile() Cleaned up header includes a bit as well. llvm-svn: 162860

No more instances, just "does the right thing". llvm-svn: 162366

* <rdar://problem/11113279>Greg Clayton2012-03-261-5/+4
| | | | | | | | | | Fixed type lookups to "do the right thing". Prior to this fix, looking up a type using "foo::bar" would result in a type list that contains all types that had "bar" as a basename unless the symbol file was able to match fully qualified names (which our DWARF parser does not). This fix will allow type matches to be made based on the basename and then have the types that don't match filtered out. Types by name can be fully qualified, or partially qualified with the new "bool exact_match" parameter to the Module::FindTypes() method. This fixes some issue that we discovered with dynamic type resolution as well as improves the overall type lookups in LLDB. llvm-svn: 153482

* <rdar://problem/10103468>Greg Clayton2012-02-241-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | I started work on being able to add symbol files after a debug session had started with a new "target symfile add" command and quickly ran into problems with stale Address objects in breakpoint locations that had lldb_private::Section pointers into modules that had been removed or replaced. This also let to grabbing stale modules from those sections. So I needed to thread harded the Address, Section and related objects. To do this I modified the ModuleChild class to now require a ModuleSP on initialization so that a weak reference can created. I also changed all places that were handing out "Section *" to have them hand out SectionSP. All ObjectFile, SymbolFile and SymbolVendors were inheriting from ModuleChild so all of the find plug-in, static creation function and constructors now require ModuleSP references instead of Module *. Address objects now have weak references to their sections which can safely go stale when a module gets destructed. This checkin doesn't complete the "target symfile add" command, but it does get us a lot clioser to being able to do such things without a high risk of crashing or memory corruption. llvm-svn: 151336

We need to do this because in the DWARF the methods for Objective C are never contained in the class definition, they are scattered about at the translation unit level and they don't even have attributes that say the are contained within the class itself. Added 3 new formats which can be used to display data: eFormatAddressInfo eFormatHexFloat eFormatInstruction eFormatAddressInfo describes an address such as function+offset and file+line, or symbol + offset, or constant data (c string, 2, 4, 8, or 16 byte constants). The format character for this is "A", the long format is "address". eFormatHexFloat will print out the hex float format that compilers tend to use. The format character for this is "X", the long format is "hex float". eFormatInstruction will print out disassembly with bytes and it will use the current target's architecture. The format character for this is "i" (which used to be being used for the integer format, but the integer format also has "d", so we gave the "i" format to disassembly), the long format is "instruction". Mate the lldb::FormatterChoiceCriterion enumeration private as it should have been from the start. It is very specialized and doesn't belong in the public API. llvm-svn: 143114

To override the new limit you can use the --show-all-children (-A) option to frame variable or increase the limit in your lldbinit file *Command "type synthetic" has been split in two: - "type synthetic" now only handles Python synthetic children providers - the new command "type filter" handles filters Because filters and synthetic providers are both ways to replace the children of a ValueObject, only one can be effective at any given time. llvm-svn: 137416
* CFString.py now shows contents in a more NSString-like way (e.g. you get ↵Enrico Granata2011-08-091-2/+2

| | | | | | | | | | | | | | | indicate that you want the summary to be used to print the target object (e.g. ${var%S}). this might already be the default if your variable is of an aggregate type new feature: synthetic filters. you can restrict the number of children for your variables to only a meaningful subset - the restricted list of children obeys the typical rules (e.g. summaries prevail over children) - one-line summaries show only the filtered (synthetic) children, if you type an expanded summary string, or you use Python scripts, all the real children are accessible - to provide a synthetic children list use the "type synth add" command, as in: type synth add foo_type --child varA --child varB[0] --child varC->packet->flags[1-4] (you can use ., ->, single-item array operator [N] and bitfield operator [N-M]; array slice access is not supported, giving simplified names to expression paths is not supported) - a new -S option to frame variable and target variable lets you override synthetic children and instead show real ones llvm-svn: 135731
* Some descriptive text for the Python script feature:Enrico Granata2011-07-161-1/+2
| | | | | | | | | | | | | | | - help type summary add now gives some hints on how to use it frame variable and target variable now have a --no-summary-depth (-Y) option: - simply using -Y without an argument will skip one level of summaries, i.e. your aggregate types will expand their children and display no summary, even if they have one. children will behave normally - using -Y<int>, as in -Y4, -Y7, ..., will skip as many levels of summaries as given by the <int> parameter (obviously, -Y and -Y1 are the same thing). children beneath the given depth level will behave normally -Y0 is the same as omitting the --no-summary-depth parameter entirely This option replaces the defined-but-unimplemented --no-summary llvm-svn: 135336
* Allow reading memory from files before the target has been run.Jim Ingham2011-07-091-4/+5

* Added "target variable" command that allows introspection of globalGreg Clayton2011-07-071-21/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | variables prior to running your binary. Zero filled sections now get section data correctly filled with zeroes when Target::ReadMemory reads from the object file section data. Added new option groups and option values for file lists. I still need to hook up all of the options to "target variable" to allow more complete introspection by file and shlib. Added the ability for ValueObjectVariable objects to be created with only the target as the execution context. This allows them to be read from the object files through Target::ReadMemory(...). Added a "virtual Module * GetModule()" function to the ValueObject class. By default it will look to the parent variable object and return its module. The module is needed when we have global variables that have file addresses (virtual addresses that are specific to module object files) and in turn allows global variables to be displayed prior to running. Removed all of the unused proxy object support that bit rotted in lldb_private::Value. Replaced a lot of places that used "FileSpec::Compare (lhs, rhs) == 0" code with the more efficient "FileSpec::Equal (lhs, rhs)". Improved logging in GDB remote plug-in. llvm-svn: 134579
* Centralized all of the format to c-string and to format character code insideGreg Clayton2011-06-231-0/+1
| | | | | | | | | | | | | | | the FormatManager class. Modified the format arguments in any commands to be able to use a single character format, or a full format name, or a partial format name if no full format names match. Modified any code that was displaying formats to use the new FormatManager calls so that our help text and errors never get out of date. Modified the display of the "type format list" command to be a bit more human readable by showing the format as a format string rather than the single character format char. llvm-svn: 133765
