This patch replaces explicit calls to log::Printf with the new LLDB_LOGF
macro. The macro is similar to LLDB_LOG but supports printf-style format
strings, instead of formatv-style format strings.
So instead of writing:
if (log)
log->Printf("%s\n", str);
You'd write:
LLDB_LOG(log, "%s\n", str);
This change was done mechanically with the command below. I replaced the
spurious if-checks with vim, since I know how to do multi-line
replacements with it.
find . -type f -name '*.cpp' -exec \
sed -i '' -E 's/log->Printf\(/LLDB_LOGF\(log, /g' "{}" +

+ dlsym the two functions we need from there at runtime.
I'm not maintaining a negative cache if DebugSymbols is absent, so
we'll try to dlopen() it on every call to
LocateMacOSXFilesUsingDebugSymbols but this file is only built on
mac and iOS type systems, so there's a slight perf impact running
lldb on an iOS type system.
I store the function pointer results in two global variables without
any locking; two threads calling into LocateMacOSXFilesUsingDebugSymbols
for the first time will both try to set these fptrs, but they'll be
setting them to the same value, so I'm not too worried.
I didn't see where in the cmake build configurations we link against
DebugSymbols, but I removed the dependency from the xcode project
file.

from 30 seconds to 120 seconds. We've seen cases where
this symbol lookup can exceed 30 seconds for people
working remotely.

Given that we have a target named Symbols, one wonders why a
file named Symbols.cpp is not in this target. To be clear,
the functions exposed from this file are really focused on
*locating* a symbol file on a given host, which is where the
ambiguity comes in. However, it makes more sense conceptually
to be in the Symbols target. While some of the specific places
to search for symbol files might change depending on the Host,
this is not inherently true in the same way that, for example,
"accessing the file system" or "starting threads" is
fundamentally dependent on the Host.
PDBs, for example, recently became a reality on non-Windows platforms,
and it's theoretically possible that DSYMs could become a thing on non
MacOSX platforms (maybe in a remote debugging scenario). Other types of
symbol files, such as DWO, DWP, etc have never been tied to any Host
platform anyway.
After this patch, there is only one remaining dependency from
Host to Target.
