Hi Jesse,
In Binutils 2.37 the ADR instruction has changed use alternate instructions.
Can you elaborate on this? What has changed exactly, and why? Looking at the commit you mention below I don't see an immediate problem that would require code changes? Also it speaks of forward references, but this one is not one? And I didn't spot any difference between 2.38 and 2.35, at least not in my isolated test (but I didn't bother to compile a whole stage 1 GCC with newer binutils yet).
Some further references Jesse provided off-list:
