New Revision: 1911a50fae8a441b445eb835b98950710d28fc88
URL: https://github.com/llvm/llvm-project/commit/1911a50fae8a441b445eb835b98950710d28fc88
DIFF: https://github.com/llvm/llvm-project/commit/1911a50fae8a441b445eb835b98950710d28fc88.diff
LOG: Deprecate the `-fbasic-block-sections=labels` option. (#107494)
This feature is supported via the newer option
`-fbasic-block-address-map`. Using the old option still works by
delegating to the newer option, while a warning is printed to show
deprecation.
