This cl introduces an incompatible flag `--incompatible_make_thinlto_command_lines_standalone`, which when flipped will change Bazel's handling of thinlto:
1) lto-backend action_config now has to be defined in the CcToolchainConfigInfo
2) lto-indexing action is split into:
* lto-index-for-executable
* lto-index-for-dynamic-library
* lto-index-for-nodeps-dynamic-library
3) all these need an action_config too
4) lto-indexing action is completely ignored
5) lto indexing command line is now defined independently of c++-link-executable, c++-link-dynamic-library, and c++-link-nodeps-dynamic-library, flags are no longer reused.
#6791
RELNOTES: Incompatible flag `--incompatible_make_thinlto_command_lines_standalone` has been added. See #6791 for details.

When set to False, the glob fails when it doesn't match anything. - Adds the "disable_whole_archive_for_static_lib" feature to allow turning off legacy_whole_archive for individual targets. - C++ Starlark API for compilation and linking is no longer whitelisted - Update visibility advice in build-style - --incompatible_disable_objc_provider_resources is now enabled by default. - Fixed an issue where some `py_runtime`s were incompatible with using `--build_python_zip` (bazelbuild#5104). - The `outputs` parameter of the `rule()` function is deprecated and attached to flag `--incompatible_no_rule_outputs_param`.

Please provide 'grpcs' as a scheme in the URLs if TLS should be used for a remote connection. - Adds incompatible_disallow_rule_execution_platform_constraints_allowed, which disallows the use of the "execution_platform_constraints_allowed" attribute when defining new rules. - Flag `--incompatible_restrict_named_params` is added. See bazelbuild#8147 for details. - The glob function has a new argument `allow_empty`. When set to False, the glob fails when it doesn't match anything. - Adds the "disable_whole_archive_for_static_lib" feature to allow turning off legacy_whole_archive for individual targets. - C++ Starlark API for compilation and linking is no longer whitelisted - Update visibility advice in build-style - --incompatible_disable_objc_provider_resources is now enabled by default. - Fixed an issue where some `py_runtime`s were incompatible with using `--build_python_zip` (bazelbuild#5104). - The `outputs` parameter of the `rule()` function is deprecated and attached to flag `--incompatible_no_rule_outputs_param`. Migrate rules to use `OutputGroupInfo` or `attr.output` instead. See bazelbuild#7977 for more info.

Flag:
--incompatible_make_thinlto_command_lines_standaloneAvailable since: 0.26
Will be flipped in: 1.0
Motivation
Before this flag,
lto-indexingaction reuses flags from plain C++ linking actions.lto-backendusesGCCtool fromtool_paths, not action configs as it should. Because of this it's unnecessary hard to configure C++ toolchain that supports ThinLTO. Once this flag is flipped, we'll document how to configure C++ toolchain for ThinLTO, and add support for ThinLTO into Bazel's autoconfigured toolchain as part of #6926.Migration
If your toolchain doesn't support ThinLTO you don't have to do anything. In case it does:
lto-backendlto-index-for-executablelto-index-for-dynamic-librarylto-index-for-nodeps-dynamic-librarylto-indexingin your toolchain, it will no longer be used by Bazel.The text was updated successfully, but these errors were encountered:
