From c7389bd69e570a2c8432b37399aff1976b021f0f Mon Sep 17 00:00:00 2001 From: Andrew Hsieh Date: Tue, 13 Mar 2012 02:13:40 -0700 Subject: 64-bit emulator Patch to allow emulator searches for emulator64-${ARCH} first on 64-bit OS. If none is found, the original behavior which searchs for 32-bit emulator-${ARCH} is performed as usual. 64-bit emulator (which still emulates Android built in 32-bit) offers up to 20% speedup compared to its 32-bit counterpart. Details: android/main-emulator.c 1) search emulator64 based on the OS 2) dlopen lib64OpenglRender in 64-bit Makefile.* 1) Rules to build 64-bit executable emulator64-{x86,arm} and libraries emulator64-{libui,libqemu,target-i386,target-arm,libelff,common} 2) remove -Wa,-32 3) Changes prebuit toolchain path android-configure.h android/build/common.h 1) no longer force 32-bit build (because now prebuilts/tools/gcc-sdk/gcc can now handle 64-bit 2) set ANDROID_PREBUILTS to correctly locate ccache android/config/*/config-host.h 1) Detect HOST_X86_64 and HOST_X86_64/HOST_I386 Misc 64-bit porting clean-up 1) use %zx to print variable of type size_t in hex 2) use %zu to print variable of type size_t in dec 3) Initialize query_parm to NULL 4) use PRIu64 to replace PDUd64 5) use PRId64/PRIu64/PRIX64 to print 64-bit 6) drop PRUx64 because PRIx64 does the same 7) cast pointer arith to intptr_t before casting to int 8) fixed 1ULL<<63 Change-Id: Ife62a20063a6ec38d4a9b23977e840af1fce149a --- target-i386/cpu.h | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'target-i386') diff --git a/target-i386/cpu.h b/target-i386/cpu.h index 88547cb..adf91cb 100644 --- a/target-i386/cpu.h +++ b/target-i386/cpu.h @@ -258,9 +258,9 @@ #define MCG_STATUS_MCIP (1UL<<2) /* machine check in progress */ -#define MCI_STATUS_VAL (1UL<<63) /* valid error */ -#define MCI_STATUS_OVER (1UL<<62) /* previous errors lost */ -#define MCI_STATUS_UC (1UL<<61) /* uncorrected error */ +#define MCI_STATUS_VAL (1ULL<<63) /* valid error */ +#define MCI_STATUS_OVER (1ULL<<62) /* previous errors lost */ +#define MCI_STATUS_UC (1ULL<<61) /* uncorrected error */ #define MSR_IA32_TSC 0x10 #define MSR_IA32_APICBASE 0x1b -- cgit v1.1
