Subject: [PATCH, i386]: Further fixes/improvements for TEST patterns

2019-07-16  Uroš Bizjak  <ubizjak@gmail.com>

    * config/i386/i386.md (*testdi_1): Match CCZmode for
    constants that might have the SImode sign bit set.
    (*testqi_1_maybe_si): Remove "!" constraint modifier.
    Use correct constraints for pentium pairing.
    (*test<mode>_1): Ditto.

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

Committed to mainline SVN.

Uros.
