From b9a7eb5db359083cf873210e5e525677c583f75a Mon Sep 17 00:00:00 2001 From: Alan Modra Date: Thu, 25 Apr 2013 10:27:16 +0930 Subject: [PATCH] config.host: Match little-endian powerpc-linux. libgcc/ * config.host: Match little-endian powerpc-linux. gcc/ * config.gcc: Support little-endian powerpc-linux targets. * config/rs6000/linux.h (LINK_OS_LINUX_EMUL): Define. (LINK_OS_LINUX_SPEC): Define. * config/rs6000/linuxspe.h (TARGET_DEFAULT): Preserve MASK_LITTLE_ENDIAN. * config/rs6000/default64.h (TARGET_DEFAULT): Likewise. * config/rs6000/linuxaltivec.h (TARGET_DEFAULT): Likewise. * config/rs6000/linux64.h (OPTION_LITTLE_ENDIAN): Don't zero. (LINK_OS_LINUX_EMUL32, LINK_OS_LINUX_EMUL64): Define. (LINK_OS_LINUX_SPEC32, LINK_OS_LINUX_SPEC64): Use above. * config/rs6000/rs6000.c (output_toc): Don't use .tc for TARGET_ELF. Correct fp word order for little-endian. Don't shift toc entries smaller than a word for little-endian. * config/rs6000/rs6000.md (bswaphi2, bswapsi2 split): Comment. (bswapdi2 splits): Correct low-part subreg for little-endian. Remove wrong BYTES_BIG_ENDIAN tests, and rename vars to remove low/high where such is correct only for be. * config/rs6000/sysv4.h (SUBTARGET_OVERRIDE_OPTIONS): Allow little-endian for -mcall-aixdesc.
