- Subject: [PATCH, committed] combine gen_int_mode PR 27282
This patch performs a little cleanup and fixes PR 27282 by
changing a GEN_INT to gen_int_mode so that a correctly sign-extended
CONST_INT is created.
Bootstrapped and regrssion tested on powerpc-ibm-aix5.2.0.0.
Approved on IRC by Roger Sayle.
