Hi,

This patch adds rtl patterns to generate bics instructions with shift.

Added attribute predicable_short_it since last respin.

Done full regression run on arm-none-eabi and arm-none-gnueabihf.
Bootstrapped on arm-none-gnueabihf.

Is this patch ok?

gcc/config

2015-04-24  Alex Velenko  <Alex.Velenko@arm.com>

   * arm/arm.md (andsi_not_shiftsi_si_scc): New pattern.
   * (andsi_not_shiftsi_si_scc_no_reuse): New pattern.

gcc/testsuite

   * gcc.target/arm/bics_1.c : New testcase.
   * gcc.target/arm/bics_2.c : New testcase.
   * gcc.target/arm/bics_3.c : New testcase.
   * gcc.target/arm/bics_4.c : New testcase.

As mentioned before, the ChangeLog entry for arm.md should
have the correct path:
     * config/arm/arm.md (andsi_not_shiftsi_si_scc): New pattern.
     (andsi_not_shiftsi_si_scc_no_reuse): Likewise.

Can you please confirm that bootstraps with both arm and thumb pass?
That is, configured with --with-mode=arm and --with-mode=thumb

If no problems there, then ok with the fixed ChangeLog entry.

Thanks,
Kyrill
