dummy.c file with a debuglink section, and again with a build-id
section, and make sure that the symbol resolution code can locate
the debug information correctly (in the binary's directory for

Fix symbol resolution by name (SymbolCache.resolve_name)
The implementation of `ProcSyms::resolve_name` was only valid for
kernel symbols, when there is no module. When a module was provided,
it would segfault due to the module being null. Fixed by making
`bcc_symcache_resolve_name` take an additional module parameter,
which, for kernel symbols, is simply null (`None` from Python).

cc: Resolve symbols from external debuginfo
Adds support for resolving symbols using external debuginfo files,
which can be retrieved from two locations. First, check the build-id
of the desired binary and look in /usr/lib/debug/.build-id according
to the build-id structure. Second, check the debuglink section of
the desired binary and look in /usr/lib/debug or in the binary's
current directory. These are the rules applied by GDB as well, but
GDB lets the user reconfigure the debug directory path from
/usr/lib/debug to something else; we do not support this.
These changes are based on the following description of how GDB
resolves external debuginfo:

cc: Correctly treat PIE files as shared objects for symbols
When resolving symbols, ProcSyms would treat position-independent
executables (PIE files) incorrectly, resulting in symbol resolution
failures. Specifically, PIE files are treated like shared objects
for ASLR, which means all symbol addresses in the file need to be
taken relative to the executable load address at runtime, the same
as with dynamic library shared objects.
The fix is in the `is_so()` method on `ProcSyms::Module`, which
now uses the correct `bcc_elf_is_shared` helper for testing if a
file is a shared object rather than just looking at the extension
".so", which is very brittle -- and wrong.

Sasha Goldshtein [Mon, 20 Feb 2017 15:42:57 +0000 (15:42 +0000)]
trace, argdist: Treat small USDT arguments correctly
trace and argdist currently only work correctly for USDT arguments
whose size is exactly 8 bytes. Smaller types, such as chars, shorts,
ints (signed or unsigned) are not treated correctly. The reason is
that the produced program would invoke the `bpf_usdt_readarg` helper
with the address of a u64 local variable, and then cast that variable
to the user-specified type derived from the format string. However,
the `bpf_usdt_readarg` rewriting then passes `sizeof(u64)` to the
generated `bpf_..._readarg` macro, which then fails to read anything
because the provided size doesn't match the argument size it knows
about.
The fix is fairly easy: instead of declaring a u64 unconditionally
and reading into that variable with `bpf_usdt_readarg`, declare a
variable that has the correct type according to what we know about
the USDT probe.

Fix for test_log_buf to work with python3
In python3, output needs to be converted from ascii to str before the
"error_msg in str" test will succeed. This change should be backwards
compatible with python2.

Use builtin clang::CompilerInvocation object
Recent llvm changed the calling convention of setInvocation, breaking
3.9/4.0 compatibility. This new approach works for both.

Explicitly mark b functions as nounwind
Without marking as nounwind, recent llvm started generating .eh_frame
section, which is invalid for bpf target jit.

Yanked all libbcc.so tests out of test/lua/test_standalone.sh
On 30 April 2016 Vicent Marti modified src/lua/CMakeLists.txt to
statically link libbcc into bcc-lua. This causes one of the tests
in test/lua/test_standalone.sh to fail, and renders all of the tests
related to libbcc.so obsolete.
