Yes, I can confirm that the binaries are different too. I uploaded all the
sample binaries and isa files:

That is the document that I looked at when I was looking for v_add_i32's
parameters. Unfortunately this only shows the microcode op code, but in the
isa, based on the three lines I pasted below, I believe the op code is
0x4A. Here are three different v_add_i32 instructions:

v_add_i32     v0, vcc, s0, v0                             // 00000050:
v_add_i32     v1, vcc, 42, v1                             // 00000058:
4A0202BF                (from sample_42.isa)
v_add_i32     v1, vcc, 0x00000063, v1               // 00000058: 4A0202FF
00000063 (from sample_99.isa)
