Hi all,
For a simple program with two consecutive reads to same registers.
0x80483e3: mov 0x8049ce0,%eax (a)
0x80483e8: mov 0x8049cd0,%eax (b)
IR generated by valgrind :
IMark(0x80483E3, 5, 0) //denotes start of an istruction
PUT(60) = 0x80483E3:I32
IMark(0x80483E8, 5, 0)
PUT(60) = 0x80483E8:I32
...
Valgrind seems to ignore redundant reads. In the example instruction (a)
doesn't generate any IR statements and hence can't be captured in the trace
as a load instruction.
Is this an expected behaviour?
Regards,
pankaj
