Instead a few things are +special cased for these. The linker also does not support PE's "grouped +sections" features, in which input objects have several named sections +that are sorted, merged, and renamed in the output file. In the past, +more sophisticated support for resources or for PE features like grouped +sections have not been necessary, as Go's own object formats are pretty +vanilla, and GNU binutils also produces pretty vanilla objects where all +sections are already merged. + +However, GNU binutils is lagging with arm support, and here LLVM has +picked up the slack. In particular, LLVM has its own rc/cvtres combo, +which are glued together in mingw LLVM distributions as windres, a +command line compatible tool with binutils' windres, which supports arm +and arm64. But there's a key difference between binutils' windres and +LLVM's windres: the LLVM one uses proper grouped sections. + +So, this commit adds grouped sections support for resource sections to +the linker. We don't attempt to plumb generic support for grouped +sections, just as there isn't generic support already for what resources +require. Instead we augment the resource handling logic to deal with +standard two-section resource objects. + +Change-Id: I059450021405cdf2ef1c195ddbab3960764ad711 +--- + src/cmd/link/internal/ld/lib.go | 2
