2012-03-09 Thread Aurelien Buhrig
Hi, It seems there is an issue around subreg:HI of PSI hardware register, which occurs either during expand or reload (GCC 4.6.1). For my big endian target, (subreg:HI (reg:PSI A0_REGNO) 0) is not representable but (subreg:HI (reg:PSI A0_REGNO) 2) is (reg:HI A0_REGNO). The issue occurs when stor
