[Qemu-devel] [PATCH 02/12] target-arm: optimize thumb 32bit multiply

2009-10-21 Thread Juha.Riihimaki
Current implementation of thumb mul instruction is implemented as a 32x32->64 multiply which then uses only 32 least significant bits of the result. Replace that with a simple 32x32->32 multiply. Signed-off-by: Juha Riihimäki --- diff --git a/target-arm/translate.c b/target-arm/translate.c in
