Sorry I've been very busy lately and didn't have a chance to try the
patches before you released them publicly. Although, I have tried the
above link and i get a 403 'Forbidden' error. I was trying to find the
arm-crunch-unwind.patch in an attempt to try to understand/debug/solve
the following problem:
I have compiled a brand new tool-chain using your 4.3.2 patch series but
I am hitting a certain bug (that also existed with the older 4.1.2
patches); an assembler error when trying to compiler certain c++ files.
The assembly generated is:
.LCFI141:
.save {mv8} <-- Error: register expected
cfstrd mvd8, [sp, #-8]!
I don't know if the arm-crunch-unwind.patch was supposed to solve this,
as it's not included in the public patches. I could give you the source
code that is causing this bug too but it's part of a large library and
therefore didn't want to clutter this message with it's details (and
patches which are needed to get it to cross-compile).
Best Regards,
