Re: Endian bug disassembling SH4 code from binary ??


Hi Mike,

Binutils version: 2.16.1

$ echo -ne ".text\nnop\nnop\n" > test.S
$ sh4-linux-uclibc-as -isa=sh4 test.S -o test.o
$ sh4-linux-uclibc-objcopy -O binary test.o test.bin
$ sh4-linux-uclibc-objdump -D -m sh4 -b binary test.bin

00000000 <.data>:
   0:   09 00     .word 0x0900   <-- Should be 'nop' !?!
   2:   09 00     .word 0x0900   <-- Should be 'nop' !?!


Is this a bug, or am I missing a critical objdump option ??
Normally you need to specify the endianness explicitly when using -b
binary.

shouldnt the default endian be whatever the toolchain is targeting though ?

Probably. In fact for me it does it appear to work this way. I tried the above test and I got the correct disassembly without having to put -EB on the objdump command line. (This was using today's binutils sources though, not the 2.16.1 release).


Andre - what was the endianness of the host machine you used to run these tests ? Also can you check to see if you still have the problem using an objdump built from the most recent binutils sources in the CVS repository ?

Cheers
  Nick
