There is already in use:
lit/lit-lldb-init:
settings set symbols.enable-external-lookup false
packages/Python/lldbsuite/test/lldbtest.py:
self.runCmd('settings set symbols.enable-external-lookup false')
But those are not in effect during MI part of the testsuite. Another problem is
that symbols.enable-external-lookup (read by GetEnableExternalLookup) has been
currently read only by LocateMacOSXFilesUsingDebugSymbols and therefore it had
no effect on Linux.
On Red Hat platforms (Fedoras, RHEL-7) there is DWZ in use and so
MiSyntaxTestCase-test_lldbmi_output_grammar FAILs due to:
AssertionError: error: inconsistent pattern ''^.+?\n'' for state 0x5f
(matched string: warning: (x86_64) /lib64/libstdc++.so.6 unsupported
DW_FORM values: 0x1f20 0x1f21
It is the only testcase with this error. It happens due to:
(lldb) target create "/lib64/libstdc++.so.6"
Current executable set to '/lib64/libstdc++.so.6' (x86_64).
(lldb) b main
warning: (x86_64) /lib64/libstdc++.so.6 unsupported DW_FORM values: 0x1f20 0x1f21
Breakpoint 1: no locations (pending).
WARNING: Unable to resolve breakpoint to any actual locations.
which happens only with gcc-base-debuginfo rpm installed (similarly for other packages).
It should also speed up the testsuite as it no longer needs to read
/usr/lib/debug symbols which have no effect (and should not have any effect) on
the testsuite results.
