--- Comment #3 from Larry Baker <baker at usgs dot gov> 2012-09-18 21:43:32 UTC --- I don't know how to attach gdb to the ld.real called by collect2. So, I added a bunch of debugging output to bfd/elflink.c to find out where the failure occurs. (I'll attach my hacked version.) Here's the link without -elf2flt and with -elf2flt. The object files/libraries are the same, yet the program sections that ld.real sees are quite different. $

Since I don't need Transactional Memory support anyway, I'm happy enough to use my patch which disables it for uClinux and move on.
