* [XLA] Switch to absl::StrFormat.Gravatar Justin Lebar2018-08-27
| | | | | | | | Unlike Printf, StrFormat does not require type-length qualifiers, e.g %z, %ll. Nor does it require that you call c_str() to print strings. So these are fixed up here as well. PiperOrigin-RevId: 210435915
* Add interface in Compiler for computing the default backend configuration of ↵Gravatar Bjarke Hammersholt Roune2018-06-19

* Add AotCompilationMetadata field to variant of CompileAheadOfTime.Gravatar Jacques Pienaar2018-06-13
| | | | | | | | | | Add CompileAheadOfTime parameter that can optionally be populated during compilation process. This change is to allow populating metadata even if the CompileAheadOfTime fails. PiperOrigin-RevId: 200407917

* Track DebugOptions in AotCompilationOptionsGravatar Sanjoy Das2018-02-26
| | | | | | In particular, I need this for supporting HLO profiling in the AOT backend. PiperOrigin-RevId: 187081674
* Use a static "linker initialized" tensorflow::mutex when possible.Gravatar Sanjoy Das2017-11-15
| | | | | | There is no need to use a lazily created tensorflow::mutex since the tensorflow::LINKER_INITIALIZED constructor is a no-op. PiperOrigin-RevId: 175874749
