commit r16-429-g62ffaef514aad0eae5d3bc548d8e86d21a3095e7
Author: Jan Hubicka <hubi...@ucw.cz>

i386: Add costs for integer<->float conversions
Extend ix86_rtx_costs to cost FLOAT, UNSIGNED_FLOAT, FIX, and UNSIGNED_FIX.
There are many variants of integer<->float conversions and it seems
meaningful to start with the typical scalar and vector ones. On modern CPUs
the
variants differs by at most 1 cycle.
gcc/ChangeLog:
* config/i386/i386.cc (ix86_rtx_costs): Cost FLOAT, UNSIGNED_FLOAT,
FIX, UNSIGNED_FIX.
* config/i386/i386.h (struct processor_costs): Add
cvtsi2ss, cvtss2si, cvtpi2ps, cvtps2pi.
* config/i386/x86-tune-costs.h (struct processor_costs): Update
tables.
