| | | | | | | | | | | | | | | | | | | | | | "thread-pcs" key is added to the T (questionmark) packet in gdb-remote protocol so that lldb doesn't need to query the pc values of every thread before it resumes a process. The only odd part with this is that I'm sending the pc values in big endian order, so we need to know the endianness of the remote process before we can use them. All other register values in gdb-remote protocol are sent in native-endian format so this requirement doesn't exist. This addition is a performance enhancement -- lldb will fall back to querying the pc of each thread individually if it needs to -- so when we don't have the byte order for the process yet, we don't use these values. Practically speaking, the only way I've been able to elicit this condition is for the first T packet when we attach to a process. <rdar://problem/21963031> llvm-svn: 255942

* Set the minimum stack size for private state thread to 8MBKate Stone2015-12-171-1/+1
| | | | | | Demangling complex Boost symbols can exhaust the default stack size. In practice, any thread that calls into LLDB functionality that touches symbols runs this risk.

* Rework breakpoint language filtering to use the symbol context's language.Dawn Perchik2015-12-165-55/+102
| | | | | | | | | | | | | | | | This patch reworks the breakpoint filter-by-language patch to use the symbol context instead of trying to guess the language solely from the symbol's name. This has the advantage that symbols compiled with debug info will have their actual language known. Symbols without debug info will still do the same "guess"ing because Symbol::GetLanguage() is implemented using Mangled::GuessLanguage(). The recognition of ObjC names was merged into Mangled::GuessLanguage. Reviewed by: jingham, clayborg Subscribers: lldb-commits Differential Revision: http://reviews.llvm.org/D15326 llvm-svn: 255808

* Fix scope-based lookup when more than one function is found.Dawn Perchik2015-12-122-0/+239
| | | | | | | | | | | | | | | | | | | | | | | | When multiple functions are found by name, lldb removes duplicate entries of functions with the same type, so the first function in the symbol context list is chosen, even if it isn't in scope. This patch uses the declaration context of the execution context to select the function which is in scope. This fixes cases like the following: int func(); namespace ns { int func(); void here() { // Run to BP here and eval 'p func()'; // lldb used to find ::func(), now finds ns::func(). } } Reviewed by: clayborg Subscribers: lldb-commits Differential Revision: http://reviews.llvm.org/D15312 llvm-svn: 255439
* Fix the L1 cache search in MemoryCache::Read to use the Jason Molenda2015-12-121-17/+9
| | | | | | | | | | | | | | | | | | | | | stl upper_bound method instead of lower_bound - we were failing to find some cached data in the L1 cache resulting in extra memory read packets while stepping. The bug with the existing code looked like this: If the L1 cache has 8 bytes at address 0x1000 and 8 bytes at address 0x2000 and we are searching for 4 bytes at 0x2004, the use of lower_bound would return the end() of the container and so we would incorrectly treat the memory as uncached. (the L1 cache is memory seeded from debugserver in the T aka questionmark packet, where debugserver will send up the stack memory that likely contains the caller's stack pointer and frame pointer values.) <rdar://problem/23869227> llvm-svn: 255421

| | | | | | | | | | | | | Adding the modules to the global module list eleminate issues in the case when a module is unloaded from the target but some object (e.g. breakpoint) still referencing them with weak pointers. It also speeds up the case when we load, unload, load the same shared library because the global module cache will keep the parsed debug info around between the 2 load (this scenario happens for some code on android).
