tda-offset out of range in sld.bu instruction
Version Information
V3.5, V4.0.5, V4.0.5c
Details
The instruction sld.bu from the V850ES core accepts only a 4-bit offset.
When using tda, the compiler generates assembler code using the sld.bu instruction with a bigger
offset and an assembler or linker error is given.
Command Line
ccv850e –cpu=v850e main.c –noobj (Assembler error)
ccv850e –cpu=v850e main.c –obj (Linker error)
Workaround
1. Do not use tiny data area (-notda)
2. Use another CPU that does not have this instruction.
