Subject: target/openrisc: Remove 'TARGET_LONG_BITS != 32' dead code
X-Git-Tag: v10.2.0-rc1~61^2~45
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=81e2fb236b702c7e172b64be4fd11aacebe50e4c;p=thirdparty%2Fqemu.git

target/openrisc: Remove 'TARGET_LONG_BITS != 32' dead code

The OpenRISC targets are only built as 32-bit:

  $ git grep TARGET_LONG_BITS configs/targets/or1k-*
  configs/targets/or1k-linux-user.mak:5:TARGET_LONG_BITS=32
  configs/targets/or1k-softmmu.mak:5:TARGET_LONG_BITS=32

Remove the dead code guarded within TARGET_LONG_BITS != 32.
