[Lldb-commits] [PATCH] D105788: [LLDB] Silence warnings from ScriptedProcessPythonInterface.cpp

[Muhammad Omair Javaid via Phabricator via lldb-commits]

omjavaid requested review of this revision.

This patch fixes ScriptedProcessPythonInterface::GetGenericInteger to
avoid compiler warning emitted due to size_t being 32 bit when built
on 32 bit paltform.

      

Tested on 32 Bit Arm (armv8l).
