Hi all,
I want to cross-compile some benchmarks so that I can run them in M5.
I'm using a ALPHA_SE mode M5 on a x86_64 Ubuntu machine. Potentially I
target to use MiBench or SPEC CPU 2000. I downloaded the pre-compiled
cross-compiler for Alpha from m5sim.org.
*1) For MiBench*, it has a simple src code/data structure with a simple
Makefile. For example, qsort, I modifed the Makefile of it as follows:
-------------------------------------------------------------------------------------------------
FILE1 = qsort_small.c
FILE2 = qsort_large.c
all: qsort_small qsort_large
qsort_small: qsort_small.c Makefile
/export/research57/weixun/tools/M5/crosstool/gcc-3.4.3-glibc-2.3.5/alpha-unknown-linux-gnu/bin/alpha-unknown-linux-gnu-gcc
-static qsort_small.c -O3 -o qsort_small -lm
qsort_large: qsort_large.c Makefile
/export/research57/weixun/tools/M5/crosstool/gcc-3.4.3-glibc-2.3.5/alpha-unknown-linux-gnu/bin/alpha-unknown-linux-gnu-gcc
-static qsort_large.c -O3 -o qsort_large -lm
clean:
rm -rf qsort_small qsort_large output*
-------------------------------------------------------------------------------------------------
I used the option "-lm" since the original "-lc" lead to errors like
"undefined references to 'exp'". If "-L
/export/research57/weixun/tools/M5/crosstool/gcc-3.4.3-glibc-2.3.5/alpha-unknown-linux-gnu/lib"
is used, the error still remains.
The compilation is successful. However, if I run it using
configs/example/se.py, I got the errors:
-------------------------------------------------------------------------------------------------

Abort
-------------------------------------------------------------------------------------------------
Other benchmarks in MiBench shows similar errors or just simplely hang
on "info: Increasing stack size by one page.".
I guess the compile options are not correct or the right library is not
linked. Please help...........................
*2) For SPEC CPU 2000*, it is more complicated. I copied the entire CD
to a local directory. The problem is I do not have the su privilege on
the machine I worked on. So the install.sh does not work correctly. Is
there a simpler way for cross-compile SPEC CPU 2000 benchmarks (or at
least some of them) for M5?
Thanks!!!
