GCC 4.9 to 5.0

GCC 4.9 to 5.0

[Victor Rodriguez]

HI everyone

Does anybody knows if there is a best known method/plan/test suite for
moving from one version of gcc to another ?

I am in the middle of that painful task and wonder if yocto community
has a plan every time yocto do this switch

Thanks a lot for all the help

Regards

Victor Rodriguez

Use the dejagnu test suite and other tests built into gcc, glibc, gdb, binutils,
and the prelinker..  (I've found the prelinker test suites sometime find obscure
issues relating to elf section handling.)

If those all pass, then most likely what you've done is in reasonably good shape.

we generate cross testing driver in the build tree for gcc-cross which should help
in running the dejagnu in cross env. Unfortunately it has stopped working after libgcc
was separated out. So it might need some fix. but you should see <cross>-testgcc script
generated in build tree.
