This revision now requires changes to proceed.
Simple logic change so we don't check the range validity more than once.
================
Comment at: source/Plugins/Process/gdb-remote/GDBRemoteCommunicationClient.cpp:1506-1510
+ // We got an invalid address range back
+ if (!region_info.GetRange().IsValid()) {
+ error.SetErrorString("Server returned invalid range");
+ }
+
----------------
Logic is fine, but I would work this into the if statement below. Something like:
```
if (region_info.GetRange().IsValid()) {
if (!saw_permissions) {
region_info.SetReadable(MemoryRegionInfo::eNo);
region_info.SetWritable(MemoryRegionInfo::eNo);
region_info.SetExecutable(MemoryRegionInfo::eNo);
region_info.SetMapped(MemoryRegionInfo::eNo);
}
} else {
// We got an invalid address range back
error.SetErrorString("Server returned invalid range");
}
```
