           Summary: armhf: generated asm code produces "branch out of
                    range" error in gas with -Os

Created attachment 32812
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=32812&action=edit
Corresponding assembly (compressed)

This is the assembly I got with the full normal command line. But I can
reproduce with the following command line:

g++ -o CertVerifier.o -c CertVerifier.ii -Os -std=gnu++0x

The problematic line is a cbz call, and i guess the label ends up at more than
130 bytes from the call.

This doesn't happen with gcc 4.9.
