[Lldb-commits] [PATCH] D63540: Fix lookup of symbols with the same address range but different binding

[Muhammad Omair Javaid via Phabricator via lldb-commits]

omjavaid added a comment.

Some new observations:

With this approach of not setting size of a non-last zero-sized symbol we somehow mange to zero out size of init (_init symbol) and .text (_start symbol).

To build and evaluate a.out   echo -e '#include <unistd.h>\nint main(void){\nsync();return 0;}'|./bin/clang -g -x c -;./bin/lldb -o 'file ./a.out' -o 'b main' -o r -o 'p (void)sync()'

Please see objdump of a.out here https://pastebin.ubuntu.com/p/N5krm5TWFV/
