- Subject: DWARF Information not Used with Wildcards
Hi,
I’ve a problem with commit 5ef0c24456e3279cda2f444e9db0a3292388cdd7.
When the commit is applied, the output of running the command (simplified)
stap -L 'process("/lib64/libcarplay-plugin-core.so").function("*").call' | grep RTPJitterBufferRead
yields
process("/lib64/libcarplay-plugin-core.so").function("RTPJitterBufferRead").call
Seemingly, the DWARF information is ignored.
When I revert the commit and run the same command, I get the following output
process("/lib64/libcarplay-plugin-core.so").function("RTPJitterBufferRead@Sources/AirPlayUtils.c:1261").call $ctx:RTPJitterBufferContext* $inBuffer:void* $inLen:size_t
What’s strange is that
stap -L 'process("/lib64/libcarplay-plugin-core.so").function("RTPJitterBufferRead").call‘
shows the correct output in both cases.
Kind Regards,
Torsten
