I want the ability to automatically generate a .note.gnu.build-id section in Go binaries. The linker currently supports a flag to get one from the outside: -B, but this is supposed to be a CRC that is calculated by the linker rather than something that can reliably be set from the outside as a linker flag.
This is used by delve and other debuggers to find split debug symbols.
What did you expect to see?
I want a flag like the binutils linker has -Wl,-build-id that adds an automatically generated .note.gnu.build-id section.
What did you see instead?
There is only a flag to set it from the outside, but it is meant to be a CRC calculated by the linker to be used reliably to differentiate different debug symbols.
