Description Serge Pavlov 2012-12-12 10:48:45 UTC

BFD linker supports option '--sort-section=name', which allows sections like .text.hot0001, .text.hot0002 etc to be placed in target executable in alphabetical order. This option has been used by Intel compiler to make function code layout more deterministic.

This feature is important for generated code performance.
