The instruction attribute table generator fails when run by mawk or original-awk: $ mawk -f arch/x86/tools/gen-insn-attr-x86.awk \ arch/x86/lib/x86-opcode-map.txt > /dev/null Semantic error at 240: Second IMM error $ echo $? 1 Line 240 contains "c8: ENTER Iw,Ib", which indicates that this instruction has two immediate operands, the second of which is one byte. The script loops through the immediate operands using a for loop. Unfortunately, there is no guarantee in awk that a for (variable in array) loop will return the indices in increasing order. Internally, both original-awk and mawk iterate over a hash table for this purpose, and both implementations happen to produce the index 2 before 1. The supposed second immediate operand is more than one byte wide, producing the error. So loop over the indices in increasing order instead. As a side-effect, with mawk this means the silly two-entry hash table never has to be built.
