/cygdrive/c/Users/exceed/AppData/Local/Temp/cc6UR3zm.s:32816: Error: branch out
of range
Problem:
I think that the length of jump table does not contains a align code.
When jump table mode is SImode, ASM_OUTPUT_CASE_LABEL generates a align code.
But length does not contains this align code. (And ADDR_VEC_ALIGN is defined to
0)
Quick hack (for 4.5 branch):
Please see attached file.
