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
