[LLVMdev] How to best add a dependency on libopagent.a/so?
I'm adding OProfile support to the JIT (patch at
http://codereview.appspot.com/89041), and I'm running into trouble
with getting llvm-config to print the right things to let external
programs link.
For some background, oprofile installs an agent library into
<prefix>/lib/oprofile/libopagent.{a,so}. This isn't on the loader's
default search path, even if <prefix>==/usr, so to link with the .so
we also need a -rpath flag to the linker. To avoid that, I'm
tentatively using the .a.
In configure, behind a --with-oprofile argument, I have:

[LLVMdev] oprofile support?
...ing to get oprofile results for jitted code without success. I
built an 3.5.0 llvm with oprofile enabled, and tested it with lli on a
small test case. I built the latest oprofile from the git repository.
Debugging I can see that lli is registering the listener and making the
oprofile calls to the libopagent api to specify the names and address
ranges of jit'd routines, and even the line number information. And the
oprofile agent is writing infomation to /tmp/.oprofile/jitdump. But
although oprofile counts lots of samples but doesnt attribute them to the
jit'd code. When execution finishes opro...
