Translate a list of operations down to micro-ops, which can be further optimized and then directly executed by backends.

Return 0 or a negative error code.

Referenced by compile(), print_ops(), and register_flags().

◆ ff_sws_uops_macros_gen()

int ff_sws_uops_macros_gen ( char ** out_str )

Generate a set of boilerplate C preprocessor macros for describing and programmatically iterating over all possible SwsUOps.

This function can be quite slow as it iterates over every possible combination of pixel formats and flags.

Returns 0 or a negative error code. On success, an allocated string is returned via out_str, and must be av_free()'d by the caller.

Additionally make sure planar reads/writes are always available for all formats, because checkasm depends on them to be able to verify the input/output of any other operations.
