have children sections).
Modified SectionLoadList to do it's own multi-threaded protected on its map.
The ThreadSafeSTLMap class was difficult to deal with and wasn't providing
much utility, it was only getting in the way.
Make sure when the communication read thread is about to exit, it clears the
thread in the main class.
Fixed the ModuleList to correctly ignore architectures and UUIDs if they aren't
valid when searching for a matching module. If we specified a file with no arch,
and then modified the file and loaded it again, it would not match on subsequent
searches if the arch was invalid since it would compare an invalid architecture
to the one that was found or selected within the shared library or executable.
This was causing stale modules to stay around in the global module list when they
should have been removed.
Removed deprecated functions from the DynamicLoaderMacOSXDYLD class.
Modified "ProcessGDBRemote::IsAlive" to check if we are connected to a gdb
server and also make sure our process hasn't exited.

all of the calls inlined in the header file for better performance.
Fixed the summary for C string types (array of chars (with any combo if
modifiers), and pointers to chars) work in all cases.
Fixed an issue where a forward declaration to a clang type could cause itself
to resolve itself more than once if, during the resolving of the type itself
it caused something to try and resolve itself again. We now remove the clang
type from the forward declaration map in the DWARF parser when we start to
resolve it and avoid this additional call. This should stop any duplicate
members from appearing and throwing all the alignment of structs, unions and
classes.

So the issue here was that we have lldb_private::FileSpec that by default was
always resolving a path when using the:
FileSpec::FileSpec (const char *path);
and in the:
void FileSpec::SetFile(const char *pathname, bool resolve = true);
This isn't what we want in many many cases. One example is you have "/tmp" on
your file system which is really "/private/tmp". You compile code in that
directory and end up with debug info that mentions "/tmp/file.c". Then you
type:
(lldb) breakpoint set --file file.c --line 5
If your current working directory is "/tmp", then "file.c" would be turned
into "/private/tmp/file.c" which won't match anything in the debug info.
Also, it should have been just a FileSpec with no directory and a filename
of "file.c" which could (and should) potentially match any instances of "file.c"
in the debug info.
So I removed the constructor that just takes a path:
FileSpec::FileSpec (const char *path); // REMOVED
You must now use the other constructor that has a "bool resolve" parameter that you must always supply:
FileSpec::FileSpec (const char *path, bool resolve);
I also removed the default parameter to SetFile():
void FileSpec::SetFile(const char *pathname, bool resolve);
And fixed all of the code to use the right settings.

being chopped up correctly). The DWARF plug-in also keeps a map of the ObjC
class names to selectors for easy parsing of all class selectors when we parse
the class type.

Added a new SortOrder enumeration and hooked it up to the "image dump symtab"
command so we can dump symbol tables in the original order, sorted by address,
or sorted by name.
llvm-svn: 116049
if the address comes from a data section.
Fixed an issue that could occur when looking up a symbol that has a zero
byte size where no match would be returned even if there was an exact symbol
match.
Cleaned up the section dump output and added the section type into the output.
llvm-svn: 116017
we cached remapping information using the old nlist index to the
new symbol index, yet we tried to lookup the symbol stubs that
were for symbols that had been remapped by ID instead of using
the new symbol index. This is now fixed and the mach-o symbol tables
are fixed.
Use the delta between two vector entries to determine the stride
in case any padding is inserted by compilers for bsearch calls
on symbol tables when finding symbols by their original ID.
llvm-svn: 113719
They will now be represented as:
eSymbolTypeFunction: eSymbolTypeCode with IsDebug() == true
eSymbolTypeGlobal: eSymbolTypeData with IsDebug() == true and IsExternal() == true
eSymbolTypeStatic: eSymbolTypeData with IsDebug() == true and IsExternal() == false
This simplifies the logic when dealing with symbols and allows for symbols
to be coalesced into a single symbol most of the time.
Enabled the minimal symbol table for mach-o again after working out all the
kinks. We now get nice concise symbol tables and debugging with DWARF in the
.o files with a debug map in the binary works well again. There were issues
where the SymbolFileDWARFDebugMap symbol file parser was using symbol IDs and
symbol indexes interchangeably. Now that all those issues are resolved
debugging is working nicely.
llvm-svn: 113678
new change will omit unneeded symbol table entries and coalesce
function entries (N_FUN stab entries) with their linker code
symbol (N_SECT symbols) into only the function symbol to avoid
duplicate symbol table entries. It will also coalesce N_STSYM and
the data linker symbol into just one static data symbol.
llvm-svn: 113363
symbol tables. Minimal symbol tables enable us to merge two symbols, one
debug symbol and one linker symbol, into a single symbol that can carry
just as much information and will avoid duplicate symbols in the symbol
table.

Arrange that this then gets properly set on attach, or when a "file" is set.
Add a completer for "process attach -n".
Caveats: there isn't currently a way to handle multiple processes with the same name. That
will have to wait on a way to pass annotations along with the completion strings.

SectionType for Section objects for DWARF.
Modified the DWARF plug-in to get the DWARF sections by SectionType so we
can safely abstract the LLDB core from section names for the various object
file formats.
Modified the SectionType definitions for .debug_pubnames and .debug_pubtypes
to use the correct case.
llvm-svn: 109054
defines that are in "llvm/Support/MachO.h". This should allow ObjectFileMachO
and ObjectContainerUniversalMachO to be able to be cross compiled in Linux.
Also did some cleanup on the ASTType by renaming it to ClangASTType and
renaming the header file. Moved a lot of "AST * + opaque clang type *"
functionality from lldb_private::Type over into ClangASTType.
llvm-svn: 109046
enabled LLVM make style building and made this compile LLDB on Mac OS X. We
can now iterate on this to make the build work on both linux and macosx.
llvm-svn: 108009
Added the ability to dump any file in the global module cache using any of
the "image dump" commands. This allows us to dump the .o files that are used
with DWARF + .o since they don't belong the the target list for the current
target.
llvm-svn: 107100
type and sub-type, or an ELF e_machine value. Also added a generic CPU type
to the arch spec class so we can have a single arch definition that the LLDB
core code can use. Previously a lot of places in the code were using the
mach-o definitions from a macosx header file.
Switches over to using "llvm/Support/MachO.h" for the llvm::MachO::XXX for the
CPU types and sub types for mach-o ArchSpecs. Added "llvm/Support/ELF.h" so
we can use the "llvm::ELF::XXX" defines for the ELF ArchSpecs.
Got rid of all CPU_TYPE_ and CPU_SUBTYPE_ defines that were previously being
used in LLDB.
