So will objdump (or llvm-objdump) with -dS, for that matter (hint: -Mintel or, on older llvm-objdump versions, --x86-asm-syntax=intel), except the line numbers

So will objdump (or llvm-objdump) with -dS, for that matter (hint: -Mintel or, on older llvm-objdump versions, --x86-asm-syntax=intel), except the line numbers in both GCC and Clang’s debug info suck in optimized builds. (Not the fault of the debug info, arguably, it’s just that the optimizer rearranges the code to the extent that the notion of line numbers makes little sense.)

> the optimizer rearranges the code to the extent that the notion of line numbers makes little sense I remember PhD papers addressing that in the 1980s. Nobody has yet figured out how to revert optimizer hamburger back into source meat.
