* Fix error handling when there are no REPLs installed.Sean Callanan2015-10-212-1/+28
| | | | | | | | Before, in the absence of any configured REPLs, LLDB would act as if there were multiple possible REPL options, whereas actually no REPL language is supported. Now we make a better error. llvm-svn: 250931
* [SBValue] Add a method GetNumChildren(uint32_t max)Siva Chandra2015-10-2114-36/+82
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Along with this, support for an optional argument to the "num_children" method of a Python synthetic child provider has also been added. These have been added with the following use case in mind: Synthetic child providers currently have a method "has_children" and "num_children". While the former is good enough to know if there are children, it does not give any insight into how many children there are. Though the latter serves this purpose, calculating the number for children of a data structure could be an O(N) operation if the data structure has N children. The new method added in this change provide a middle ground. One can call GetNumChildren(K) to know if a child exists at an index K which can be as large as the callers tolerance can be. If the caller wants to know about children beyond K, it can make an other call with 2K. If the synthetic child provider maintains state about it counting till K previosly, then the next call is only an O(K) operation. Infact, all calls made progressively with steps of K will be O(K) operations.

* [DataFormatters] Make libc++ list loop detection linearPavel Labath2015-10-211-88/+113
| | | | | | | | | | | | | | | | | | | | | | | | | Summary: Loop detection code is being called before every element access. Although it tries to cache some of the data by remembering the loop-free initial segment, every time it needs to increase this segment, it will start from scratch. For the typical usage pattern, where one accesses the elements in order, the loop detection will need to be run after every access, resulting in quadratic behavior. This behavior is noticable even for the default 255 element limit. In this commit, I rewrite the algorithm to be truly incremental -- it maintains the state of its loop-detection runners between calls, and reuses them when it needs to check another segment. This way, each part of the list is scanned only once, resulting in linear behavior. Also note that I have changed the operator== of ListEntry to do the comparison based on the value() function (instead of relying on ValueObjectSP equality). In my experiments, I kept getting different ValueObjectSPs when going through the same element twice.

* [RenderScript] New commands to save/load RS allocations to file.Ewan Crawford2015-10-212-40/+410
| | | | | | | | | | | | | | Patch adds command 'language renderscript allocation save' to store the contents of an allocation in a binary file. And 'language renderscript allocation load' to restore an allocation with the saved data from a binary file. Binary file format contains a header FileHeader with meta information preceding the raw data.

| | | | | | | | | | | | Loading the debug info from a large application is the slowest task LLDB do. This CL makes most of the dwarf parsing code multi-threaded. As a result the speed of "attach; backtrace; exit;" when the inferior is an LLDB with full debug info increased by a factor of 2 (on my machine).

* Increase default memory cache line size for androidPavel Labath2015-10-203-0/+17
| | | | | | | | | | | | | | | | Summary: ADB packets have a maximum size of 4k. This means the size of memory reads does not affect speed too much (as long as it fits in one packet). Therefore, I am increasing the default memory read size for android to 2k. This value is used only if the user has not modified the default memory-cache-line-size setting.

* Fix temporary directory computation on linux (pr25147)Pavel Labath2015-10-162-19/+13
| | | | | | | | | | | | | | | | | | | | | | | | Summary: On linux, the environment variables for temp directories that lldb checks for are generally not defined, and the temp directory computation failed. This caused expression evaluation to fall back to creating "/tmp/lldb-*.expr" debugging files instead of the usual "$TMP/lldb/pid/lldb-*.expr". Crucially, these files were not cleaned up on lldb exit, which caused clutter in the /tmp folder, especially on long-running machines (e.g. builtbots). This commit fixes lldb to use llvm::sys::path::system_temp_directory, which does the same environment variable dance, but (!) also falls back to the P_tmpdir macro, which is how the temp directory is defined on linux. Since the linux temp path computation now succeeds, I needed to also modify Android path computation to check for actual directory existence, rather then checking whether the operation failed.
