From e85e7c6ea411c42e24e6e7b8ff5cdd99faae317a Mon Sep 17 00:00:00 2001 From: j_mayer Date: Thu, 18 Oct 2007 19:59:49 +0000 Subject: [PATCH] Use the new TARGET_ABI32 feature to implement a ppc64abi32-linux-user target (PowerPC 64 running in 32 bits mode). Use the new TARGET_ABI_DIR feature to implement a ppcemb-linux-user target (PowerPC 32 with 64 bits GPRs and vector extensions). git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@3409 c046a42c-6fe2-441c-8c8c-71466251a162 --- configure | 11 ++++++++++- linux-user/elfload.c | 6 +++--- linux-user/main.c | 18 +++++++++++------- 3 files changed, 24 insertions(+), 11 deletions(-) diff --git a/configure b/configure index 221c068..492707a 100755 --- a/configure +++ b/configure @@ -504,7 +504,7 @@ if test -z "$target_list" ; then fi # the following are Linux specific if [ "$linux_user" = "yes" ] ; then - target_list="i386-linux-user arm-linux-user armeb-linux-user sparc-linux-user sparc64-linux-user sparc32plus-linux-user mips-linux-user mipsel-linux-user m68k-linux-user alpha-linux-user sh4-linux-user ppc-linux-user ppc64-linux-user x86_64-linux-user cris-linux-user $target_list" + target_list="i386-linux-user arm-linux-user armeb-linux-user sparc-linux-user sparc64-linux-user sparc32plus-linux-user mips-linux-user mipsel-linux-user m68k-linux-user alpha-linux-user sh4-linux-user ppc-linux-user ppcemb-linux-user ppc64-linux-user ppc64abi32-linux-user x86_64-linux-user cris-linux-user $target_list" fi # the following are Darwin specific if [ "$darwin_user" = "yes" ] ; then @@ -937,6 +937,7 @@ target_bigendian="no" [ "$target_cpu" = "ppc" ] && target_bigendian=yes [ "$target_cpu" = "ppcemb" ] && target_bigendian=yes [ "$target_cpu" = "ppc64" ] && target_bigendian=yes +[ "$target_cpu" = "ppc64abi32" ] && target_bigendian=yes [ "$target_cpu" = "ppc64h" ] && target_bigendian=yes [ "$target_cpu" = "mips" ] && target_bigendian=yes [ "$target_cpu" = "mipsn32" ] && target_bigendian=yes @@ -1040,6 +1041,7 @@ elif test "$target_cpu" = "ppc" ; then echo "#define TARGET_PPC 1" >> $config_h elif test "$target_cpu" = "ppcemb" ; then echo "TARGET_ARCH=ppcemb" >> $config_mak + echo "TARGET_ABI_DIR=ppc" >> $config_mak echo "#define TARGET_ARCH \"ppcemb\"" >> $config_h echo "#define TARGET_PPC 1" >> $config_h echo "#define TARGET_PPCEMB 1" >> $config_h @@ -1048,6 +1050,13 @@ elif test "$target_cpu" = "ppc64" ; then echo "#define TARGET_ARCH \"ppc64\"" >> $config_h echo "#define TARGET_PPC 1" >> $config_h echo "#define TARGET_PPC64 1" >> $config_h +elif test "$target_cpu" = "ppc64abi32" ; then + echo "TARGET_ARCH=ppc64" >> $config_mak + echo "#define TARGET_ARCH \"ppc64\"" >> $config_h + echo "TARGET_ABI_DIR=ppc" >> $config_mak + echo "#define TARGET_PPC 1" >> $config_h + echo "#define TARGET_PPC64 1" >> $config_h + echo "#define TARGET_ABI32 1" >> $config_h elif test "$target_cpu" = "ppc64h" ; then echo "TARGET_ARCH=ppc64h" >> $config_mak echo "#define TARGET_ARCH \"ppc64h\"" >> $config_h diff --git a/linux-user/elfload.c b/linux-user/elfload.c index 0bb455b..fbfa3b0 100644 --- a/linux-user/elfload.c +++ b/linux-user/elfload.c @@ -269,7 +269,7 @@ static inline void init_thread(struct target_pt_regs *regs, struct image_info *i #define ELF_START_MMAP 0x80000000 -#ifdef TARGET_PPC64 +#if defined(TARGET_PPC64) && !defined(TARGET_ABI32) #define elf_check_arch(x) ( (x) == EM_PPC64 ) @@ -325,13 +325,13 @@ static inline void init_thread(struct target_pt_regs *_regs, struct image_info * { abi_ulong pos = infop->start_stack; abi_ulong tmp; -#ifdef TARGET_PPC64 +#if defined(TARGET_PPC64) && !defined(TARGET_ABI32) abi_ulong entry, toc; #endif _regs->msr = 1 << MSR_PR; /* Set user mode */ _regs->gpr[1] = infop->start_stack; -#ifdef TARGET_PPC64 +#if defined(TARGET_PPC64) && !defined(TARGET_ABI32) entry = ldq_raw(infop->entry) + infop->load_addr; toc = ldq_raw(infop->entry + 8) + infop->load_addr; _regs->gpr[2] = toc; diff --git a/linux-user/main.c b/linux-user/main.c index 1388d48..7c39121 100644 --- a/linux-user/main.c +++ b/linux-user/main.c @@ -1008,7 +1008,7 @@ void cpu_loop(CPUPPCState *env) "Aborting\n"); break; #endif /* defined(TARGET_PPCEMB) */ -#if defined(TARGET_PPC64) /* PowerPC 64 */ +#if defined(TARGET_PPC64) && !defined(TARGET_ABI32) /* PowerPC 64 */ case POWERPC_EXCP_DSEG: /* Data segment exception */ cpu_abort(env, "Data segment exception while in user mode.
