--- Comment #7 from ian at gcc dot gnu.org <ian at gcc dot gnu.org> --- Author: ian Date: Fri Jan 30 00:36:14 2015 New Revision: 220269 URL: https://gcc.gnu.org/viewcvs?rev=220269&root=gcc&view=rev Log: compiler: Fix -fgo-prefix handling. There was bug in the fix for PR 61880: it only worked fully correctly for code compiled with -fgo-pkgpath. For code that used -fgo-prefix, or that used neither option, the '.' separating the prefix and the package name was converted to an underscore, which did not happen before. This broke SWIG and any other code that expected specific symbol names. Fortunately all code compiled in libgo and all code compiled by the go tool uses -fgo-pkgpath, so this probably did not affect very many people. This is an incomplete fix that does not modify the package file format, for use on both mainline and the GCC 4.9 branch. A follow on patch will fully fix the problem.
