They are fixed in current CVS, but at 3.1 release time there will not be a released binutils containing these fixes. Frame unwinding is not reliable without these fixes. >How-To-Repeat: Build current CVS 3.1 on a Sparc target with currently released binutils. Most testsuite failures will be due to the eh_frame being wrong. >Fix: Implement configure bits to detect binutils with the problem, and disable using eh_frame optimizations if so. >Release-Note: >Audit-Trail: >Unformatted:
