Left shifts always insert 0s, so logical and arithmetic shifts are the 
same.  'sal' is just some gas-specific alias to 'shl'.

Just s/sal/shl in Mplayer, or:

$ grep shl i386-asm.h
ALT(DEF_ASM_OP3(shldw, 0x0fa4, 0, OPC_MODRM | OPC_WL, OPT_IM8, OPT_REGW, 
OPT_EA | OPT_REGW))
ALT(DEF_ASM_OP3(shldw, 0x0fa5, 0, OPC_MODRM | OPC_WL, OPT_CL, OPT_REGW, 
OPT_EA | OPT_REGW))
ALT(DEF_ASM_OP2(shldw, 0x0fa5, 0, OPC_MODRM | OPC_WL, OPT_REGW, OPT_EA | 
OPT_REGW))

So dup each of these lines, replacing shldw with saldw. That should 
teach tcc that gas rubbish too. :)
