#7 print.c:277:1: error: unrecognizable insn:

[Ludovic Rousseau]

I try to rebuild the current git version of gnu-efi (commit 644898eabc06c8efaa3aa54f84cdd468960a2f6c) and I get:

I have the same problem using gcc 4.7 and gcc 4.8. It is really a GCC internal compiler error or a problem with gnu-efi?

[Nigel Croxon]

it's a new problem introduced in the last commit (644898eabc06c8efaa3aa54f84cdd468960a2f6c)

[Nigel Croxon]

The current git tree compiles, no errors on CentOS 6.5 - gcc version 4.4.7 20120313 (Red Hat 4.4.7-4) (GCC).
But I see the failure on Fedora 20 - gcc version 4.8.2 20131212 (Red Hat 4.8.2-7) (GCC)
