Hi,
I am trying to use m5_reset_stats and other m5 calls from my benchmark (i
am trying to instrument the hooks.c file in PARSEC benchmark so that i can
get my stats around the ROI). I run into "illegal instruction" while
exexcuting m5_reset_stats.
On further analysis, using objdump the m5ops_arm.o file contains the
following mnemonic.
00000058 <m5_reset_stats>:
* 58: ee400110 .word 0xee400110 b*
5c: e1a0f00e mov pc, lr
The corresponding section in the .S file contains the following assembly
code (substitute func with 0x40 and subfunc with 0x0)
.long 0xEE000110 | (\func << 16) | (\subfunc << 12)
mov pc,lr
Clearly, the instruction at 0x58 is not a valid instruction. I could not
understand the real intent of the .long construct in the .S file. i believe
the intent was to convey a "code" to the underlying machine through a valid
instruction. Attempt was to accomplished by the bit-manipulation. It seems
to have gone wrong. Can someone help me here to fix the problem?
