2015-07-25dump reasons why graphite failed to detect a scopSebastian Pop2-6/+74
When trying to analyze why Graphite does not handle a loop nest, it is easy to look in the dumps of -fdump-tree-graphite-all to guess what has to be changed to catch the loop.

During the gccgo build define constants from some header files are processed by mksysinfo.sh and added to syscall.go.
