@AlexVlx If you don't mind, let's do this function as the following:
```
SPIRV::Scope::Scope getMemScope(LLVMContext &Context, SyncScope::ID Id) {
// Named by
// https://registry.khronos.org/SPIR-V/specs/unified1/SPIRV.html#_scope_id We
// don't need aliases for Invocation and CrossDevice, as we already have them
// covered by "singlethread" and "" strings respectively (see implementation
// of LLVMContext::LLVMContext()).
static llvm::SyncScope::ID SubGroupSSID =
Context.getOrInsertSyncScopeID("subgroup");
static llvm::SyncScope::ID WorkGroupSSID =
Context.getOrInsertSyncScopeID("workgroup");
static llvm::SyncScope::ID DeviceSSID =
Context.getOrInsertSyncScopeID("device");
if (Id == SyncScope::SingleThread)
return SPIRV::Scope::Invocation;
if (Id == SubGroupSSID)
return SPIRV::Scope::Subgroup;
if (Id == WorkGroupSSID)
return SPIRV::Scope::Workgroup;
if (Id == DeviceSSID)
return SPIRV::Scope::Device;
if (Id == SyncScope::System)
return SPIRV::Scope::CrossDevice;
// This function assumes that known memory sync scopes may appear to be the
// non-exhaustive list and allows to use the most conservative/safe choice as
// the default in case of an unknown SyncScope::ID value.
return SPIRV::Scope::CrossDevice;
}
