reg-stack.c (compare_for_stack_reg): Add bool argument.
* reg-stack.c (compare_for_stack_reg): Add bool argument.
Detect FTST instruction and handle its register pops. Only pop
second operand if can_pop_second_op is true.
(subst_stack_regs_pat) <case COMPARE>: Detect FCOMI instruction to
set can_pop_second_op to false in the compare_for_stack_reg call.
* config/i386/i386.md (*cmpi<FPCMP:unord><MODEF:mode>): Only call
output_fp_compare for stack register operands.
* config/i386/i386.c (output_fp_compare): Do not output SSE compare
instructions here. Do not emit stack register pops here. Assert
that FCOMPP pops next to top stack register. Rewrite function.
