The old disassembler is easier to follow:
----------------
IN:
-0x4000d214: lda [ %g3 ] #ASI_M_FLUSH_PROBE, %g6
-0x4000d218: sta %g6, [ %g4 ] #ASI_M_FLUSH_PROBE
+0x4000d214: cc80c060 .byte 0xcc, 0x80, 0xc0, 0x60
+0x4000d218: cca10060 .byte 0xcc, 0xa1, 0x00, 0x60
^ lda/sta opcodes not supported (there might be more).
----------------
IN:
-0x4000d22c: sethi %hi(0xf01f0000), %g1
-0x4000d230: mov %g1, %g1 ! 0xf01f0000
-0x4000d234: jmp %g1
-0x4000d238: nop
+0x4000d22c: 033c07c0 sethi 0x3c07c0, %g1
+0x4000d230: 82106000 or %g1, 0, %g1
+0x4000d234: 81c04000 jmp %g1
+0x4000d238: 01000000 nop
^ hi()/lo() macros not expanded (easier to read!)
Can we restrict dumping the encoded hex content for debug
profile only?
Anyhow:
