Hi there, i am interested to know how is backtrace (https://www.gnu.org/software/libc/manual/html_node/Backtraces.html) enabled in Swift. From what i understand, flag like
--export-dynamic is need to pass to the linker when building swift/swiftc. However, when I look for those flags in the CMake files within swift source directory and the
build.ninja file in the building directory , i could not find any.
I wonder what makes backtrace work without those flags being passed. Further, where should i pass those flags if i need to?
