Bug ID: 42754
Summary: llvm-addr2line does not exit when passed a
non-existent file
Product: tools
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: llvm-symbolizer
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
GNU addr2line and FreeBSD addr2line exit immediately when passed an invalid
file with -e:
$ addr2line -fi -e /bad/file
addr2line: /bad/file: No such file or directory
However, llvm-addr2line does not exit and waits for input on stdin.
This causes compiler-rt/test/asan/TestCases/Posix/asan-symbolize-bad-path.cc to
block forever if -DLLVM_INSTALL_BINUTILS_SYMLINKS=ON is enabled.
In that case the addr2line found in the path will be llvm-addr2line and then
the test waits forever.
I wonder if we want to change llvm-addr2line (and possibly also
llvm-symbolizer) to behave in the same way as GNU?
