--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> 2012-02-08 08:37:41 UTC --- Created attachment 26607 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=26607 gcc47-pr52150.patch Untested fix. I took the liberty to also overwrite the last _ with . or $, so that at least when possible these artificial symbols don't clash with user __gcov__foo etc. symbols (yeah, I know, they are reserved for implementation, still the assembly would likely fail if those were used).
