* [Remarks] Extend -fsave-optimization-record to specify the formatFrancis Visoiu Mistrih2019-06-171-0/+5
| | | | | | | | | Use -fsave-optimization-record=<format> to specify a different format than the default, which is YAML. For now, only YAML is supported. llvm-svn: 363573
* [Remarks][NFC] Improve testing and documentation of -foptimization-record-passesFrancis Visoiu Mistrih2019-06-141-0/+3
| | | | | | | | | | | This adds: * documentation to the user manual * nicer error message * test for the error case * test for the gold plugin llvm-svn: 363463
* Reland "[Remarks] Add -foptimization-record-passes to filter remark emission"Francis Visoiu Mistrih2019-03-121-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | Currently we have -Rpass for filtering the remarks that are displayed as diagnostics, but when using -fsave-optimization-record, there is no way to filter the remarks while generating them. This adds support for filtering remarks by passes using a regex. Ex: `clang -fsave-optimization-record -foptimization-record-passes=inline` will only emit the remarks coming from the pass `inline`. This adds: * `-fsave-optimization-record` to the driver * `-opt-record-passes` to cc1 * `-lto-pass-remarks-filter` to the LTOCodeGenerator * `--opt-remarks-passes` to lld * `-pass-remarks-filter` to llc, opt, llvm-lto, llvm-lto2 * `-opt-remarks-passes` to gold-plugin Differential Revision: https://reviews.llvm.org/D59268 Original llvm-svn: 355964 llvm-svn: 355984

* Add an option to save the backend-produced YAML optimization record to a fileHal Finkel2016-10-111-0/+33
The backend now has the capability to save information from optimizations, the same information that can be used to generate optimization diagnostics but in machine-consumable form, into an output file. This can be enabled when using opt (see r282539), and this change enables it when using clang. The idea is that other tools will be able to consume these files, and perhaps in combination with the original source code, produce various kinds of optimization reports for users (and for compiler developers). We now have at-least two tools that can consume these files: * tools/llvm-opt-report * utils/opt-viewer Using the flag -fsave-optimization-record will cause the YAML file to be generated; the file name will be based on the output file name (if we're using -c or -S and have an output name), or the input file name. When we're using CUDA, or some other offloading mechanism, separate files are generated for each backend target. The output file name can be specified by the user using -foptimization-record-file=filename. Differential Revision: https://reviews.llvm.org/D25225 llvm-svn: 283834
