Modifying the define_asm_attributes to maximum possible length of a 
single machine instruction solved the issue. 
Thanks very much for the suggestion.

Thanks & Regards,

See define_asm_attributes for a way to estimate the length of an inline
asm instruction.  In the worst case, you can use this to make every
inline asm large enough to force the use of a long branch.
