Re: [klee-dev] measuring the coverage using the test cases testN.TYPE.err

[Andrew Santosa]

Hi BNM,
If I understand correctly, here there are two categories of test suites 
discussed: one contains the test suite generatedby KLEE, and another contains 
test suites that come with the program itself. If you want to measure the 
coveragespecifically achieved by KLEE, then you should only run your program 
with the KLEE-generated test suite.

 Hello,
I've tried to measure the code coverage of a program using Gcov with the test 
cases generated by KLEE . The test suites include some test cases reporting 
some errors, is it necessary to include these test cases when I measure the 
coverage or should be excluded?

Re: [klee-dev] SSE Support?

[Owl Owl]

Yeah I spent a few hours last night trying to compile libc with that flag.
It doesn't seem possible since functions like atof necessarily have to use
SSE for the return value.

With respect to a SSE disabled version of QEMU


The gcc compiler has options of the form -no-sse*
My uninformed guess (i.e. I have not tried it) is the use of those options 
would be the key.

You probably will have to build your own versions of libc and QEMU using those 
options

[klee-dev] SSE Support?

[Owl Owl]

Folks,

Is there symbolic support for SSE regs? The amd64 ABI specifies that SSE
must be present on those architectures, and i have not been successful in
convincing libc to NOT use SSE enabled versions of it's functions.

Looking for information on either KLEE support for this, or how to force an
application in QEMU into using non-SSE libc functions.

Aside: Given how things are evolving, it would appear that SSE will simply
grow more prevalent and harder to avoid...

Best,

Mike
