This is extension to https://golang.org/cl/113955 that handled duplicated "unresolved relocation" errors. For platforms with trampoline support, additional error is generated per each undefined symbol. This breaks TestUndefinedRelocErrors test on these platforms. Proposed fix: 1. Changes error text to be identical to normal undefined reloc. If relocation is undefined, jump to it will be unresolved as well. 2. Introduces a map that can be used by all sites that handle this kind of errors which makes it easier to report such errors exactly once. Errors on ppc64 before this change (note first 4 lines): main.defined1: unresolved inter-package jump to main.undefined() main.defined1: unresolved inter-package jump to main.undefined() main.defined2: unresolved inter-package jump to main.undefined() main.defined2: unresolved inter-package jump to main.undefined() main.defined1: relocation target main.undefined not defined main.defined2: relocation target main.undefined not defined runtime.main_main·f: function main is undeclared in the main package After this change: main.defined1: relocation target main.undefined not defined main.defined2: relocation target main.undefined not defined runtime.main_main·f: function main is undeclared in the main package Because of (1), errors output is the same on all platforms now.
