... and use TARGET_BONNELL in ix86_add_stmt_cost.
Now that TARGET_VECTORIZE_DOUBLE is used only as a cost option in
ix86_add_stmt_cost, there is no point to have a tuning option that
covers a single target in a single place.
2016-10-04 Uros Bizjak <ubiz...@gmail.com>
* config/i386/x86-tune.def (X86_TUNE_VECTORIZE_DOUBLE): Remove.
* config/i386/i386.h (TARGET_VECTORIZE_DOUBLE): Remove.
* config/i386/i386.c (ix86_add_stmt_cost): Use TARGET_BONNEL instead
of !TARGET_VECTORIZE_DOUBLE when penalizing DFmode vector ops.
Bootstrapped and regression tested on x86_64-linux-gnu {,-m32},
committed to mainline SVN.
Uros.
