Recent versions of GNU binutils starting from 2.39 support symbol+offset
lookup in addition to the usual numeric address lookup. This change adds
symbol lookup to llvm-symbolize and llvm-addr2line.
Now llvm-symbolize behaves closer to GNU addr2line, - if the value specified
as address in command line or input stream is not a number, it is treated as
a symbol name. For example:
llvm-symbolize --obj=abc.so func_22
llvm-symbolize --obj=abc.so "CODE func_22"
This lookup is now supported only for functions. Specification with
offset is not supported yet.
This is a recommit of 2b27948783, reverted
in 39fec5457c because the test
llvm/test/Support/interrupts.test started failing on Windows. The test was
changed in 18f036d010 and is also updated in
this commit.
