gcc49-pr59308.patch
Patch (only tested on x86_64-linux with
--target_board=unix\{-m32,-m32/-march=i386,-m64\} where some of those tests
previously also failed with -march=i386 variant).
Though, I wonder if it wouldn't be better to just compile or run those tests
just on targets which do support -mbranch-cost=2 option
(mips/avr/s390/i?86/x86_64) and ignore all other targets. The tests are
testing GIMPLE behavior anyway.
