Subject: [PATCH, i386]: Tighten inline_secondary_memory_needed to reject moves between (SSE,mask) and non-general regs

2019-08-29  Uroš Bizjak  <ubizjak@gmail.com>

    * config/i386/i386.c (inline_secondary_memory_needed): Return true
    for moves between SSE and non-general registers and between
    mask and non-general registers.
    (ix86_register_move_cost): Remove stalled comment.

Bootstrapped and regression tested on x86_64-linux-gnu {,-m32}.

Committed to mainline SVN.

Uros.
