The asm at spinlock.h:25 doesn't directly use r1. I think the only way this might happen is 'a' is spilled to the stack at a very large offset from the stack pointer. The load of the offset may need r1. There also has to be some other code that has stolen r1 prior to the asm. The register allocation and inlining in gcc various significantly from one version. So, a different gcc version might work better. At least one version of gcc seemed to want to nest asm's. To debug, preprocessed source and exact gcc command line is needed. Dave -- J.
