sh: Remove implicit sign extension from assembler immediates 2009-08-24T08:09:53+00:00 Stuart Menefy stuart.menefy@st.com 2009-08-24T08:09:53+00:00 fea966f7564205fcf5919af9bde031e753419c96 The SH instruction set has several instructions which accept an 8 bit immediate operand. For logical instructions this operand is zero extended, for arithmetic instructions the operand is sign extended. After adding an option to the assembler to check this, it was found that several pieces of assembly code were assuming this behaviour, and in one case getting it wrong. So this patch explicitly sign extends any immediate operands, which makes it obvious what is happening, and fixes the one case which got it wrong.
