[Lldb-commits] [PATCH] fix cross compilation to 32 bit arm targets

[Vince Harron]

Hi zturner, granata.enrico,


After syncing to ToT, I started getting this error when cross compiling to an arm target.

```
/usr/local/google/home/vharron/ll/cross/llvm/tools/lldb/include/lldb/Utility/ProcessStructReader.h:68:74: error: non-constant-expression cannot be narrowed from type 'unsigned long long' to 'size_t' (aka 'unsigned int') in initializer list [-Wc++11-narrowing]
                m_fields[const_name] = FieldImpl{field_type, byte_index, size};
                                                                         ^~~~

```

This patch adds a cast to fix the error.  The cast is non-controversial because it comes after (size <= 8) is confirmed.
