This is actually linked to my remark on build-time source instrumentation on https://github.com/golang/go/issues/35204 : I insert hooks into functions and then use a lookup table to find them at run time. Currently, they are created using a function which adds the newly created pointer into a global map, thus done at "Go init time". But if we say that I shouldn't add new dependencies when from a -toolexec tool, I need to create this same lookup table differently. TBH, I just would like to know if getting a symbol address at link time is possible. Because I actually found today a workaround to be able to add new dependencies my -toolexec tool. But I may need to do this later on. The other idea I had in mind was using the gosymtab to find function adresses but it looks like this section is not always present and I am not sure how long it will be supported. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
